Electric Double Wall/Built-in Whirlpool Oven Dead? Could be open thermal fuse

Electronic Control Board for Whirpool Double Electric Oven

Electronic Control Board for Whirpool Double Electric Oven

 

Does your oven display look like this?  Is the oven completely dead, whether or not you’ve already had the control board rebuilt by a PCB repair company?  This is probably just the result of an open fuse in-line with the black “hot” wire to the control board transformer.

 

Check for continuity through thermal fuse in-line with black wire, then 120VAC across black and white wires

Check for continuity through thermal fuse in-line with black wire, then 120VAC across black and white wires

Use an ohmmeter to check for continuity through the fuse.  If open, it needs to be replaced.   If the fuse is OK, but the board is totally dead, check that there is 120VAC across the “hot” wire with fuse and white neutral wire in the caddy-corner wiring harness.  If you’re getting 120VAC there but the board is still completely dead, consult a PCB repair company to get the board repaired.

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…
