Whirlpool Oven – Common Problems and Causes

This post is a quick overview of common problems with the popular Whirlpool board series: 8303883, 8302967, 8302319, 8301345, 8301917, 8301908,4451856, 4451991, 4452890, 4452898 and 4453664.   Here, at, we are well acquainted with all these problems.  This guide will help you troubleshoot oven control problems at home.  If, indeed, the problem is in the control board, don’t hesitate to send it to us for a quick, quality repair backed with a two year warranty.

Control Board Front View Control Board Back View

    • E6/F2 Error Code ->   Always a problem with control board

This is the most common symptom and can only be due to the control board. Since the techsheet decodes this to “cancel key line drive open”, many people suspect the keypad is bad. The keypad is not causing an E6/F2. Based on years of experience, E6/F2 is never anything other than the control board….. Send it in.

Whirlpool Oven Panel E6 F2 Error CodeWhirlpool Oven Panel E6 F2 Error Code
    • E1/F5 Error Code ->   Can be control board, door lock or keypad

Wait a minute! The techsheet decodes it to “Self-clean latch will not lock” . How could the keypad cause this? Good question. On models with a manual door lock for the lower oven, the keypad has a special short between pins 1 and 11. This tells the control board not to cycle the door lock on the lower oven because there is no motorized door lock to control. If this short is missing, eventually the control board will flash the E1 error code on the right side of the clock display.
If the E1 is on the left of the clock, it is complaining about the upper oven. In this case, the keypad cannot be responsible. Once you determine the door lock is functioning correctly, the problem is with the control board.

Whirlpool Oven Panel F5_E1 Error Code
    • E1/F2 only ->   Always a problem with the keypad

This code means the board did not detect the keypad. Once again, this is based on years of experience. Never have we seen the control board causing this problem.

    • E0/F3 and E2/F3 ->   Almost always a problem with the control board

If the temp sensor measures approximately 1050 ohms when measured at the white connector on the control board, the problem is likely the control board.

    • Blank Display (With Beeps) ->   Problem is the control board

The beeps at power up, mean the board is getting power. If the display stays off after beeping, there is a problem with the control board

    • Blank Display (No Beeps) ->   If input power is ok, problem is control board

If you are getting approximaely 24V from transformer but the display is blank, the control board is the problem.

We hope this helps you quickly troubleshoot common problems with this Whirlpool series. Remember, if you have a symptom that is puzzling or new, contact us at and we can help you figure it out. Thank you for your business!

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 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, and you’ll get it back working just like new in a few days.

I hope you found this guide helpful!

Thermador Oven Control Board 486752 / 14-33-347 – Door Lock Sequence and Errors

Are you having door lock problems with your Thermador control board 486752 or 14-33-347,  487604 or 316080103.   At, we get questions about the door lock operation for this controller.  This post addresses this by describing the sequence of events when the controller is programmed for a clean cycle.    We hope this information will help you  troubleshoot door lock issues with the following model numbers: RDDS30, RDDS30QW, RDDS30V, RDDS30VQB, RDDS30VQB, RDDS30VRS, RDDS30VRS, RDFS30, RDF30, RDF30QB, RDF30QW, RDF30RS, RDF30RS, RDSS30, RED30V, RED30VQB, RED30VQRS, RED30VQW, REF30, REF30QB, REF30QW, REF30RS, RES30, RES30QB, RES30RS, RES30W, RDDS30, RDDS30QW, RDDS30, RDDS30V, RDDS30VQB, RDDS30VRS, RDFS30, RDF30, RDF30QB, RDF30QW, RDF30RS, RDSS30, RED30V, RED30VQB, RED30VQRS, RED30VQW, REF30, REF30QB, REF30QW, REF30RS,  RES30,  RES30QB,  RES30RS,  RES30W.

State 1 -Clean Button Pressed and Time Set  (Door still unlocked)

Note that the blue display show that clean mode has been selected and the total time for the clean mode.  The state of the switches is shown in the diagram.  Pins 7 and 8 are shorted together with switch #1.  This is the un-locked state.


State 1 -Display As Soon as Clean Time is Programmed

State 2 – Automatic Door Locks are Running (One Second after State 1)

After a second in state 1, the following happens:

  1. The clean light comes on.
  2. Controller turns on the door lock motor.
  3. This state only last until motor releases switch 1 and pins 7 and 8 are no longer connected.




State 3 – Lock Motor Still Spinning and Switch #1 is Not Pressed anymore.

Pins 7, 8 and 9 are not connected and the motor is still spinning.

Note that the display shows the “locked” even though switch #2 is not pressed yet and door is not locked.  




State 4 – Lock Motor has Stopped Spinning Because Switch #2 shorted pin 7 to 9.  Oven has turned on the heating elements.

Note that the display now says “ON”.  This means that switch #2 was pressed by the lock motor which shorted pin 7 to 9.  The oven will now reach cleaning temperature.




State 5 – Fault State.  If the controller does not sense the door lock on pins 7 and 9.

In this fault mode, the controller will beep and show door on the screen.


Error State – Control did not receive the locked signal on pins 7 and 9.

Meaning of F1,F2,F3,F4,F5,F6,F7 codes for Garland/Manitowoc Ovens

Garland oven controllers are programmed to give meaningful information if they enter into a fault condition.  This applies to most Garland ovens such as models: UCO-G-5, ECO-G-10, ECO-G-20, ICO-G-10, ICO-G-20, IC0-E-10 , ICO-E-20, ECO-E-10, ECO-E-20,MP-ES, MP-ED, MP-GS, MP-GD, PaceSetter EC-I-36, EC-II-36, EC-I-42, EC-II-42, GC-I-36,GC-II-36,GC-I-42,GC-II-42, Trendsetter ovens TE3, TE4, TTE3, TTE4, TE3/4-x, TTE3/4-X, TE3/4ECH, TTE3/4ECH, TG2A, TG3,TG4,TTG3,TTG4, Sunfire SDG-1 and SGD-2, TE2A, KFC MCO-G-5K and others.

Many times the result of the F code troubleshooting points to the control board /Timer/ERC.  Don’t worry, they can be rebuilt even if the part is no longer available (NLA) or obsolete.  With , you will never have to scrap a commercial oven due to failed electronics.

Some part numbers that throw F-codes are: 1517700, 1517701, 1517702, 1517703,1544800, 1517704,1517705, 1517706, 1517710 ,1544801, 1933801, 1933701,4521705,4521282, 4515873, 1025299, 1025204,1034199, 1244705, 1285601, 1025204, 1244704, 1285700, 1905701, 1025204,1244705, 1905601 among others.

Here is a summary of the fault codes and their meaning:

F1Relay Output is Enabled When Not Cooking. The cook relay is closed with no call for heat.
-Control should be rebuilt.

F2 Over Temperature Alarm. The control is sensing an oven temperature 50 degrees or more above the
maximum temperature of 500F
-Check the probe wiring and the probes resistance  and replace if faulty
-If probe is functional, rebuild control.

F3Open Probe Circuit. The control is sensing an open circuit at the probe input.

-Check the probe wiring and the probes resistance and replace if faulty.

-If probe is functional, rebuild control.

F4Shorted Probe Circuit. The control is sensing a short circuit at the probe.
-Check the probe wiring and the probes resistance and replace if faulty
-If probe is functional, rebuild control.

F5Relay outputs not enabled when cooking. The control is in cook mode and the heat relay is not closing.
-The control should be rebuilt

F6No 60Hz input. The control does not sense the input power.
-Check the power supply for noise
-If the supply is correct, rebuild control.

F7 EEPROM. The control has detected that the calculated EEPROM check sum is incorrect.

-Reset power to control and if problem persists, rebuild control.

Send Dacor ERD, ERSD, CPS Control Boards For Repair

Dacor ovens have control boards that can be refurbished to extend the life of your oven.  The models include but are not limited to ERD30, ERSD30, ERG30, ERD36, ERDS36, ERG36, ERD48, ERDS48, ERD30S06, CPS227, CPD227, CPS230, CPD230, CPS127, CPS130, PGR30S.   Common errors include beeping F0, F1, F2, F3, F4, F5, F6 and E0 errors, blank displays and oven not reaching temperature.  These errors can be fixed  quickly and reliably at  Along with the failed component, all other components prone to failure are also replaced.  This means many more years of worry-free oven operation after a control board rebuild.

Once it is suspected that the oven has a control board problem, it usually makes sense to remove all of the control boards to be inspected and repaired.  This page will show you the location of these boards.  As always, make sure all power to the oven is turned off and take pictures or notes to facilitate the re-installation process.

If you have a single oven there is one “display board” and the other a “relay board”.  If you have a double oven, there is one display board and two relay boards.  By far, the majority of problems are due to the display control board, but if you suspect an issue with the relay board, it can be tested/rebuilt too.

Common part numbers for the display board are: 701002, 701003, 701004, 701005, 701006, 701007, 62180, 62181, 62182 ,62151, 62789, 62790, 62692, 62681, 82381, 82382, 82758.

These look similar to this:

The location of the display board can be seen in the following diagram:

The relays board/s will look similar to:

The relay boards can be found using the following diagram:

Once you have your notes/pictures for reference.  Remove the control boards, wrap it with some cushioning and put it in a box.  Most control boards will be fixed, tested and returned to your door step within a week.

You Don’t Have to Scrap Your Oven Just Because the Low Voltage Transformer is Obsolete

We get calls from owners of expensive ovens in search of a transformer equivalent to replace a failed, no-longer-available low voltage oven transformer. These transformers sometimes fail due to a power surge, a lightning storm induced transient, self clean cycle or an over temperature condition.

The problem is that there are typically multiple output voltage windings on these devices which makes it difficult to cross to an off-the-shelf part. Nobody wants to scrap out an entire oven just because the low voltage transformer has failed and supply of a new replacement has been discontinued by the manufacturer.

In response to this need, we have developed a method to test and, when possible, repair these devices. In most cases we have found that the transformer can be reliably and safely repaired.

If your oven transformer has failed consider sending it to us at FixYourBoard for repair. Don’t scrap your oven without considering this cost effective, environmentally responsible alternative!

Some example part numbers are: 205C2191P002 WB20K5008 WB20K5063 WB20X10005 which are used in a variety of GE ovens similar to these models: JCTP16 JKP17 JKP18 JKP44 JKP45 JKP55 JKP54 JKP56 JTP16 JTP17 JTP18 JTP44 JTP45 JTP55 JTP56 ZEK734 ZEK736 ZEK737 ZEK754 ZEK755 ZEK756 ZEK757 and many others.

How to Remove an Oven Control Board

If you own an oven, chances are at some point you will need to access the electronics behind the control panel.  Doing it yourself can save you some money and is easy to do on most ovens.  Regardless of what you may hear, the control boards on all appliances are repairable.  Many times, control board repair is the only option because they are obsolete or no longer available from the manufacturer.  A good example of a repair service company is

This posting shows the basic steps for removing a control board from a built-in electric Whirlpool model .  A similar process applies to Kitchenaid, GE, Thermador, Dacor, Jennair and many others. This process is just as easy on most other oven brands and once you do it, you will be glad you tackled the job.  All you usually need is a screw driver and a refreshing drink.  This post covers the basic steps that one should follow.

1.  Turn Off Power to Oven

This is the single most important step.  This is for your safety and to protect the electronics of the oven.  Removing power ensures that no wires will be shorted to other metal parts.   This is done with the circuit breaker.  Find the right one and make sure it turns off all lights in the oven and control panel.

2.  Remove Mounting Hardware

Front View Screw Locations

Side view of screws holding control panel

This whirlpool has mounting screws for the support brackets on the sides of the oven door.  These can be removed by opening the door and removing the holding screws.

3.  Take Notes and Pictures

Now, the control panel should be loose and you can pull it out to see what is behind the control panel.  This is great time to take some notes and pictures.  This is quick to do and you will glad you did once it is time to re-install the control board.

Behind Front Touchpad

In most cases as in this one, you will see the control board attached to the front panel.  Again, before you remove the control board from the panel or disconnect any wires, it is recommended that you take some snapshots before going any further.

Once the connections are removed and the control board is free, all you have to do is wrap it with some cushioning and put it in a box.  Most control boards will be fixed, tested and returned to your door step within a week.
