Evaporator Fan Installation Kit For KSS, KSC, and other Whirlpool/KitchenAid/Kenmore/JennAir/Maytag Refrigerators

Another helpful tip from the members of a PCB repair shop!

bizcard_gen_small

There has been a lot of confusion surrounding the installation process of a new evaporator fan motor for these KitchenAid (and other Whirlpool Corp.) refrigerators.  Whirlpool provides one replacement kit that is applicable to three different style of refrigerators.  Depending on which style refrigerator you have, you may or may not have to use one of the two jumper harnesses included in the kit to connect the fan motor to the main control board.

Skip to the end of this post to read the installation instructions published by Whirlpool Corp…

BUT, we can sum it up for you in a much clearer fashion:

1) CUT POWER TO THE REFRIGERATOR.

2) Remove the original fan motor. Disconnect the fan motor from the jumper wiring harness that goes to the main control board, but leave this jumper harness in place.  Whirlpool suggests using a flat head screwdriver to unlock the plug, as it is fragile and can break.

3) Install the new fan motor where the old one used to be.

4) Depending on which style of refrigerator you have, you may or may not need to connect the motor to the control board via one of the two jumper wiring harnesses included in the kit:

REFRIGERATOR TYPEJUMPER TO BE USED
Built-in with bottom Freezer

Plain Jumper Harness for Built-in Refrigerators with Bottom Freezer



Add this harness between the original one and the new fan motor.
Counter Depth

Jumper Harness with Defrost Bi-metal for Counter Depth Refigerators



Remove the original bi-metal jumper harness and replace it with this new one.
Built-in Side by SideNONE. Simply, use the original jumper harness that was already in the refrigerator.

The installation kit should have include a black dot sticker.  After the fan motor replacement is complete, apply this sticker to the right of the main power ON/OFF switch behind the upper grille in the machine compartment.

Restore power to your fridge and everything should be good to go.  Remember, get your refrigerator control board problems solved by PCB repair companies!

 

Original Installation Instructions Per Whirlpool Corp.:

This evaporator motor service kit is supplied with one evaporator
motor that can be used for a KitchenAid built-in bottom freezer,
KitchenAid built-in side-by-side, or Counter Depth refrigerator.
This evaporator motor service kit is also supplied with a new
jumper harness for the KitchenAid built-in bottom freezer
(Figure 1) and a new defrost bi-metal harness for the Counter
Depth refrigerators (Figure 2).

Plain Jumper Harness for Built-in Refrigerators with Bottom Freezer

Figure 1: Plain Jumper Harness for Built-in Refrigerators with Bottom Freezer

NOTE: Must remove existing harness on Counter Depth ONLY
and replace with harness in the kit

If the evaporator motor is being replaced on one of these units,
the jumper harness connected to the motor must be removed
along with the old evaporator motor.

1. Unplug the refrigerator or disconnect power.

2. Use a small flat screwdriver to unlock the plug, slight
pressure is needed to release the lock. Use care, the lock
is easily broken. The two harnesses contained in the kit
are required when the new motor is being replaced.
Replacement of the harnesses to the individual product is
needed for a proper repair and for proper operation.

Figure 2: Defrost Bi-Metal Jumper Harness for Counter Depth Refigerators

3. If the product is a Counter Depth refrigerator, the old
defrost bi-metal harness connected to the evaporator fan
jumper harness must be removed. This harness contains a
9-pin connector and the defrost bi-metal. For the Counter
Depth refrigerator ONLY, replace the old defrost bi-metal
harness with the new defrost bi-metal harness contained
in the kit (Figure 2).

If the product is a KitchenAid built-in bottom freezer,
connect the jumper harness (approximately 265-mm)
contained in the kit (Figure 1) to the new evaporator fan
motor.

If the product is a KitchenAid built-in side-by-side, no
jumper harness is needed.

4. Secure all connections.

5. Replace all parts and panels.

6. Plug in refrigerator or reconnect power.

7. Perform the service diagnostic mode by pressing and
holding the Water Filter Reset key first then the Power key
and hold both for 3 seconds. Verify that in step 3 of the
service diagnostic mode, the evaporator motor receives a
green LED indicator on the display for the Counter Depth
product or “01” on the display for the KitchenAid built-in
bottom freezer and for the KitchenAid built-in side-by-side
products.

NOTE: If the call service indicator is still flashing, press
the Over Temperature Reset key.

8. After replacement is completed, the black dot that is
included in this kit needs to be placed to the right of the
main power switch behind the upper grille in the machine
compartment. (See Figure 3.)

Whirlpool Double Oven (Gold, GBD, RBD series) not heating? Could be an open thermal fuse.

Hello!

Today’s article will help you figure out why the bake/broil elements in your oven(s) aren’t heating up, even though the control panel seems to be operating perfectly.  In fact, you may even have recently received a refurbished/repaired control unit from www.FixYourBoard.com, but the oven still won’t heat up.  Fear no longer – this blog will get you on the right track in no time.

This guide is for troubleshooting Whirlpool double ovens – please refer to the list of relevant part and model numbers at the bottom of this blog to ensure you are in the right place.

First off, does your control panel seem to be functional? If the display isn’t illuminated, and there are no beeps when you press buttons, but you’re positive you’ve properly hooked up the control board and have the breaker on, then you may have an issue with the power supply to the control board.  Please refer to this guide for troubleshooting the power supply.

So everything seems to be properly connected.   You set the oven to bake, the display shows that the heat is on (the door needs to be closed), but the oven elements aren’t heating up at all, and the control is not throwing any error codes.  This is almost certainly being cause by an open “oven shutdown thermal fuse”.  There is one of these fuses for both the lower oven and the upper oven, each.  Hopefully, you’re only having this problem in one of the two, but it wouldn’t be too surprising if both thermal fuses went out, and it’s not hard to replace them.   Now, if the elements do heat up, even if it’s just a little bit, then the problem is either with the oven (temperature) sensor or the oven control board – please refer to this blog for troubleshooting that issue.

 

CUT THE BREAKER!!! These next steps involve measuring circuit elements that run at HIGH VOLTAGE WHICH CAN KILL YOU when the breaker is on.

You’ll want to have a DMM or DVM (Digital Multi/Voltage Meter) that can measure electrical resistance.  There is a large variety of inexpensive meters available.  Below are two different kinds of meters – both are set to check for electrical resistance of up to 200 ohms (Ω).  Set your meter to the 200 Ω scale, and make sure the probes are connected to the common (black) and voltage (red) ports.

Typical Digital Multi-Meter (DMM) set to the 200 Ω scale.

Typical Digital Multi-Meter (DMM) set to the 200 Ω scale.

First, let’s make sure the actual heating elements are not the problem.  You need to have the control board exposed, but still hooked up to the oven, and THE BREAKER SHOULD BE OFF. Near the element relays are the wiring tabs where the heating elements connect to the control board.  The upper oven elements are fed by the set of tabs labeled P18.  There should be two black wires on the two center tabs, and a red wire and an orange wire which connect to the outside tabs.  Stick your probes into the sockets where the orange and red wires connect to the board – you should be in the ballpark of 50 Ω.  The lower oven is fed by the other set of tabs, labeled P26.  Here, we want to stick the probes into the sockets occupied by the red (outside) and orange (center) wires – should also be around 50 Ω.   If these measurements check out, skip the rest of this paragraph.  If either one of these measurements are significantly far from 50 Ω (e.g. <35 Ω or >65 Ω) , or especially if the meter over-ranges (usually meters display a “1” on the far right of the screen when they over-range), then you need to individually inspect the element(s) in question.  Oven models are unique so I can’t give specific information on how to extract the heating elements from the oven cavity – you may want to have a technician do this with you – but it’s usually just a matter of removing some mounting screws, and you may have to get behind the oven to disconnect the wiring.  The heating elements are essentially long metal rods bent into a radiator-like shape (they’re basically radiators, after all).  The resistance from end-to-end of a broil (top) element should be about 20 Ω, and it should be about 30 Ω for a bake (bottom) element.  If any of these elements fail to meet approximate spec, they should probably be replaced – contact a technician.  If the elements are fine, but the measurements on the control board were bad, then it’s a wiring/connection issue.

So the elements aren’t the problem, but the thermal fuses could still definitely be bad – let’s see.  For these ovens, there are two different styles of control boards, which we’ll refer to as 2319 and 2697.  The easy way to tell which one you have is by looking at the right side of the back of the board: if it has two DLB (Double Line Break; photos below) relays, then it is a 2319, otherwise it’s a 2967.  Go to the appropriate paragraph.

Whirlpool Double Oven Control Board 8302967 – no DLB relays.

Whirlpool Double Oven Control Board 8302319 – has DLB relays.

Often, Whirlpool Control Board 8302319 is in a Plastic Case.

Troubleshooting 2319

Your board has the DLB relays.   Let’s check the upper oven thermal fuse first.  The upper oven DLB relay should have two solid red wires connected to it, and we need to figure out which one to use for the fuse test.  First, with your meter set to the 200 Ω scale, hold a probe to each of the contacts for the red wires – it should over-range, meaning that it is an open circuit (if your meter registers any resistance within the 200 Ω scale, then the relay is stuck and you need to send the board to www.FixYourBoard.com to be repaired).  Now, look at the other (lower oven) DLB relay.  This one should have one solid red wire, and one red wire with a white stripe.  The solid red wire on the lower oven DLB relay should be in closed circuit to one of the solid red wires on the upper oven DLB relay, and it should be open circuit to the other solid red wire.  Use your meter to find out which one – the meter should register a value (somewhere around 20-30 Ω) for the closed circuit, and it should over-range for the open circuit.  We want to use the solid red wire on the upper oven DLB that is open circuit to the solid red wire on the lower oven DLB.  Hold one of the probes to the contact for that solid red wire, and stick the other probe into either the orange or red wire socket connected to the P18 tabs.  This should be a closed circuit.  If it is an open circuit, the upper oven thermal fuse is open and needs to be replaced – take a note of that for now.

Now let’s look at the lower oven thermal fuse.  Hold one of your probes to the contact for the red wire with a white stripe that connects to the lower oven DLB relay.  Stick the other probe into the orange wire socket connected to the P26 tabs.  This should be a closed circuit.  If it is an open circuit, the upper oven thermal fuse is open and needs to be replaced.  Skip the 2967 troubleshooting paragraph to see about replacing these fuses.

Troubleshooting 2967

Your board does not have the DLB relays.  With your meter set to the 200 Ω scale, stick one of the probes into the socket for either the red or the orange wire that connects to the P18 tabs on the board.  Stick the other probe into the socket for the orange wire that connects to the P26 tabs.  In normal conditions, this should be a closed circuit – the meter should read a value around 40-60 Ω.  If the meter over-ranges, then either one or both of the thermal fuses are open.

Bad Thermal Fuse

The meter has told us one or both of the thermal fuses are bad.  These are mounted on the rear panel(s) of the oven(s), so you’re going to have to pull the double oven out from the kitchen wall to access them.  Open up the rear panel(s) of the oven(s) (some hardware will probably required), and you should find the thermal fuses mounted on the panel.  A red wire and an orange wire should be connected to one side of the fuse, while just one red wire is connected to the other side of the fuse.  This will be true of both the upper and lower thermal fuses, with one exception: if your oven is not self-cleaning, the lower thermal fuse will only have one orange wire on one side and one red wire on the other.  Disconnect the wiring and unmount the suspect fuse(s).  Use your meter to verify that the fuse(s) is/are open – holding one probe to each of the contacts should result in over-ranging in the 200 Ω scale if the fuse is open.  Contact a local appliance parts supplier or a site like www.RepairClinic.com to find the necessary replacement according to the part number and/or color markings on the fuse…

Dead GE double oven? Transformer or Controller? Troubleshooting Guide

This guide will help you identify what problems you may have in the power supply to the electronics in your GE double oven.  Some symptoms you may be experiencing include, but are not limited to:
  • Blank display or no beeping
  • F1 error code
  • Oven seems dead

Generally, these are signs of a failed controller, but sometimes blank display or dead oven are simply the result of a failed transformer.  I say “simply” because it is much less expensive and much easier to replace/fix the transformer than it is the controller.  The objective of this post is to help you figure out which is the faulty part so you can send the right one to www.FixYourBoard.com to be repaired.

You’ll need an AC voltmeter as well as a basic tool set handy (pretty much just the right sized screwdriver).

The first thing to do is cut the breaker to your oven before you start taking it apart – we don’t want anybody getting killed by high voltage.

Next, you’ll need to expose your controller.  Refer to this post for help if you don’t know how to access the control unit.  There is no need to disconnect anything – that could actually make your measurements useless.  Once it’s exposed, make sure you can comfortably touch the various wiring harnesses with the voltmeter probes.  If it’s going to be a struggle, you may want to demount the unit from the panel to get some more slack.

Now, turn the breaker back on.  You’ll need to be very careful from here on.  Even though the controller is mostly a low voltage device, there are still points of high voltage on the relay board, and you can still cause electrical damage if you probe the wrong places.  Wall power goes into a transformer somewhere off the control module, and the transformer steps the wall power down to low voltage and routes that to the control board.  The low voltage comes into the board at the white wiring connector labeled J1.  It’s near the black connector receiving the clear, thin ribbon cable from the keypad (see photo).

The transformer sends two separate low voltages to the control board, 21.5 VAC and 4.6 VAC.  These voltages are approximate: as long is you’re in the ballpark, you should be good.  Also, it’s important to note that there are many variations of this control module.  Yours may look a bit different from the one depicted below, but you should still be getting the same supply from the transformer.  The photo shows a unit with all the wiring detached – yours should have a wiring harness occupying the J1 connector, but you should be able to stick the voltmeter probes along the wires into the sockets of the harness to take measurements.  If not, cut the breaker, disconnect the harness from J1 connector, turn the breaker back on, and probe the bottom side of the harness.  You should measure voltages according the photo.  Note that the empty slot is referred to as pins 3.

GE double oven electronic control board

Probes on pins 1 and 2 is one measurement. Probes on pins 4 and 5 is a separate measurement. The empty slot is referred to as Pin 3.

If you measure the proper voltages, then you know the transformer is not the issue.  Make sure the wiring harness is well connected, clean, and making good contact.  If you’re still having problems as described at the beginning, then the controller is the problem, and you should send it to FixYourBoard.com for repair.

If you aren’t reading these voltages, then you either have a bad transformer, or bad wiring.  Cut the breaker, and follow the wires back to the transformer.  These four wires come out of the secondary side of the transformer.  There should be another two wires going into the other side of the transformer, the primary side.  With the breaker on, you should measure 120VAC going into the primary.  I shouldn’t need to tell you how DANGEROUS 120VAC is.  If you measure 120VAC at the primary, check to see if you get 21.5 and 4.6 right at the secondary.  If not for either one, then the transformer is definitely bad and you should contact FixYourBoard.com for repair.  If you have these voltages right at the transformer, but not at the board, then the wiring has broken down somewhere between and needs to be fixed.  If you’re not getting 120VAC into the transformer primary, then you have a serious electrical wiring problem in your wall which should be addressed by a professional (e.g. electrician).

Whirlpool oven is dead – no display, no beeping. Does the control board need to be repaired?

Young Padawan, here, with another guide from FixYourBoard.com.  We’ve been witnessing some confusion people are having in diagnosing their power supplies for Whirlpool ovens, and whether or not they should send the board in to FixYourBoard.com for repair.  Hopefully this will help clear that up!

To make a good diagnosis, you’ll need to have a voltmeter that can measure AC voltages up to over 120 V.  And please exercise caution when making these measurements – you could shock yourself with high voltage which can kill you! If you’ve cut the breaker to your oven, you’ll need to throw it back on.

Before we begin, there are three quick-checks that ensure you have power getting to your board properly:

1) If the control board makes any kind of beep, then you know your power supply is good.

2) If the display is in anyway illuminated, then your power supply is good.

3) For the third quick-check, stick your voltmeter probes into slots 2 and 3 of the wiring harness that attaches to connector P16 (there should be two blue wires coming into these same slots; see second photo below).  Make sure your probes are making contact with metal – either uninsulated portion of the wire or connector pins inside the harness.  You should measure 24 V AC here.  If not, go on with the rest of the guide.

If your board passes any of the quick-checks but you are still experiencing any of the common problems or some kind of malfunction, then you should send it in to FixYourBoard.com for repair.

Without further ado, the full troubleshooting guide.  Power to the oven control board goes through three stages…

STAGE ONE – power into the board?

120 V AC wall power comes into the board through the P24 wiring connector at pins 1 and 3.  Pin 1 is denoted by the small triangular arrow printed on the actual circuit board.  The space for pin 2 is empty, so when I refer to “pin 3”, it’s actually the second physical pin to occur in this connector.  That can certainly be confusing!  L1 (black wire) comes into pin 3, and Neutral (white wire) comes into pin 1 (see photo below).  The incoming power wires attach to this connector by a wiring harness with a corresponding number of slots.

With a voltmeter, you should measure about 120 V AC by sticking one probe in slot 1 and the other probe in slot 3 (make sure the probes are making contact with the metal wire or pin, not just the insulation around the wire).   If so, scroll down to Stage Two.  If you don’t measure any voltage across these slots, you could have an open thermal fuse (see photo above), which is in series with the incoming black L1 wire.  Keep one probe in slot 1 (Neutral) and move the other to the side of the thermal fuse that is coming from the wall (not the side that goes into the board).  You should measure 120 V AC here.  If you do, then you need to replace the thermal fuse.  If you don’t, then you have an electrical wiring issue in your wall and should contact a professional electrician.

STAGE TWO – power to the transformer?

The circuitry in the control board reroutes power to an off-board transformer.  The power is sent to-and-fro the transformer at connector P16 (see photo below).  First, let’s make sure that 120 V is going to the transformer.  L1 comes out at pin 5 and Neutral comes out at pin 7 (both should be red wires).  Hold your probes in these slots and you should measure 120 V AC across them.  If not, then you definitely have a board problem and should send it in to FixYourBoard.com for repair.

If 120 V AC is coming out of the board, then let’s make sure it’s getting to the transformer.  The wires from the transformer (both wires should be blue) connect at pins 2 and 3 on the P16 connector.  *CUT THE BREAKER TO YOUR OVEN* Some model ovens have the transformer more easily located for removal than others, but we need to be safe before going fishing through all these wires for it.  You should be able to find it by following the blue and red wires coming from the P16 connector.  You may need to pull your oven out from the wall.  Once you have a hold of it, place the transformer somewhere where you can probe it while still being connected to the board, but it’s not being shorted to any other metal or wires.

Being positive that the transformer and wiring is all electrically safe (not shorting to anything), throw the breaker back on.  Hold your voltmeter probes to the two small tabs where the red L1 and neutral wires attach (see photo below) – you should measure about 120 V AC.  It’d be unlikely, but if you don’t measure 120 V AC here and you were getting it out of the board at P16 pins 5 and 7, then the wires or their connections are somehow damaged and need to be replaced or re-soldered.  That kind of damage should be visually apparent.

STAGE 3 – stepped-down power back to the board?

The transformer’s job is to reduce (step-down) the high voltage a lower amount that”s easier and safer for the electronics.  Hold your probes to the two larger tabs on the transformer where the blue wires attach (see photo above).  You should measure 24 V AC here.  If not, then you have a bad transformer.  These are still available and relatively inexpensive.  You can do a Google search of your model number or use a website like RepairClinic.com to find the transformer you need.

If you do measure 24 V AC at the tabs, then ensure it’s getting to the board.  Power from the transformer travels through the blue wires back into the board at connector P16 pins 2 and 3.  Stick your probes in the corresponding slots (where the blue wires come in) on the wiring harness that connects to P16 – you should measure 24 V AC. If you do measure 24 V AC coming out at the transformer, but not back into the board at the P16 connector pins 2 and 3, then it’s again some kind of wiring/connection problem that should be visually apparent.

Reminders:

– In making any measurements with your probes, you need to be sure that you are touching conductive material, like exposed portions of the wires or pins.

– Throughout the course of troubleshooting, you’ve had to throw the breaker a couple times.  It needs to be ON (supplying electricity to the oven) when you check voltages on the board/transformer.

– All measured voltages will be approximate to the nominal values listed throughout the guide.

DANGER HIGH VOLTAGE! Enough said.

That concludes the power supply troubleshooting guide.  I hope you found it helpful!

Whirlpool Gold Oven, GBD and RBD series Electronic Control Board (ECB) Wiring Connector Removal

So you need to send your Whirlpool ECB (specific model and part numbers listed at bottom of this post) to FixYourBoard.com for a quality repair, but you can’t get the blasted thing out the oven because it’s held in by a bunch of wiring connectors.  You don’t want to further damage the board in the removal process, and we don’t want you to either.  Here’s a straight-forward, visually enhanced guide to help take the stress out of your kitchen.

Make sure you have a flat-head screwdriver handy – it makes everything a lot easier.

Click here for instructions on how to access your control module if you need help.

Once you’ve exposed the control module, the first step is to safely detach the ribbon cable.  This is the most fragile part in the whole unit, and if damaged, you’ll have to replace your keypad, which can be costly.  It is essential that you do not crease the ribbon cable – this will break the wires.  Regardless of your model oven, the ribbon cable attaches to the board at the black connector labelled P22.  It is held firmly in place through a slide-in locking mechanism.  To release this mechanism, simultaneously press in the two clips on each end of the connector and then pull up (away from the board).   It might be a little sticky, but shouldn’t require much force.  Now, gently pull the ribbon cable out of the connector, and then out the the housing through the large rectangular gap (if it was coming through the gap).  Again, it is important that some curvature is retained in the ribbon cable – do not fold it too much when pulling it out.

P22 – Ribbon Connector

The second step is to get the actual board out of the black plastic housing module (wires still attached).  Unscrew the housing from the panel first – this will give you some more room to manoeuvre.  Next, let’s slide out the small daughter card on the exterior side.  It’s only held in by one clip on the top edge.  Pull that back so you can slide the card up and out of the housing (wires still attached).

Daughter Card

Now, looking down into the housing, you can see that the board is held in by 6 clips, 3 running the length of each side.  We only need to unclip one side to pull the board out.  I find it easier to focus on the side opposite the P22 ribbon connector.  Notice the semicircular gaps in the housing near the clips.  Let’s start at the corner in between the white connectors P24 and P16.  With one hand, position your flat-head pointing down onto the top of the board, inside the housing, and push the lip of the clip out.  Simultaneously, with your other hand, place your thumb on the bottom side of board where the semicircular gap is and push the board up past the lip.  Repeat this procedure for the middle clip on this side, and then the third clip on the end opposite where we started.  Note that there are no gaps immediately near the middle clip, but you can still use the first gap just as effectively.  Your flat-head will be especially useful for the third clip if your board has the two DLB relays with the sockets on top (as pictured below).

Unclip this side of the board

Start with this clip

Second clip

Third Clip

Once this half of the board has been unclipped, you can free the board from the housing with a little bit of wiggling, sliding the other half out from underneath the clip lips.  With the board free from the housing, removing the wires form the connectors is easy.

If your board has the socketed DLB relays, the attached wires can simply be pulled free.

DLB relay with wires attached

The heating elements’ wiring attaches to the board through the large black female connectors.  These can be pried free with your flat-head inserted between the board  and the connector.  The white connectors can also be pried apart, inserting your flat-head between the male connector mounted on the board, and the female connector attached to the wiring.

Black Connectors to Heating Elements

Separating the white connectors

Now your control board should be completely free from any attachments.  Package it with care (no need to send the daughter card or housing), send it to FixYourBoard.com, and you’ll get it back working just like new in a few days.

I hope you found this guide helpful!
