SOURCE: convection upper oven not heating.

I Have worked on quite a few of these in the last few weeks, i have found that about 50% of these problems are caused by the control board and the other 50% caused by the thermal fuse, you can check the fuse by removing the unit from the wall and checking for continuity at the thermal fuse. If the fuse is in fact ok then it is the board that is not sending the correct amount of power to the elements. So the Power Control Board is what will need to be replaced, you can purchase both of these parts at, http://www.reliableparts.com/ by using your model number.

Please rate my solution if it was helpful to you.

If you need more in depth information or pictures on how to remove and take this machine apart, feel free to ask.

Thanks, Repairman45

Where do I locate the fuses that controls the oven heating.


Hello Pat;

My name is Peter. I am a retired field service appliance technician.

When you go into self cleaning both of your burner element peak at there max temperature, well above 500 degrees F.

1.) Oven Element - Over time the elements will fail. Turn the upper element on. Inspect for sparking where there may be a crack in the element. Turn the upper element off, inspect for any cracks.

If there are no cracks then you lower element is fine.

2.) Each of your ovens have a independent thermocouple. Both may have failed due to the extreme heat. Oven thermocouples will fail on older units.

3.) Lets go to the source. You have what is called a infinite switch in your oven. This switch controls your oven temperature. If this switch fails then your oven will not work.

Ok, lets assume you or a friend are good with tools. With a multi-meter set to the lowest Ohms, In the back of your oven there is a sheet metal cover. Remover the cover, disconnect the two contacts on each thermocouple, and Ohm them out. (Power Off at your breaker box first) You should get a reading of '0' Ohms, anything else the thermal couples are bad.

But, I tend to believe, You have a bad infinity switch. You can also Ohm this out as above with a reading of '0' Ohms.

This component is about $35.00 USD.

If I were still working for Sears Home Services I would charge you $350.00- $450.00 for this service call. Send me your model number and let me see what you have. goodwinpeg@aol.com.

Whirlpool gbd307 why will The upper oven not work but the lower oven works


Have you checked the heating element supply voltage with a VOM? And have you checked for a popped/burned fuse to the bake element?

Jtp45 lower oven hot heating on any cycle


Possibly a tripped thermal fuse. Should be located behind the panel in between the upper and lower ovens. Might have a red reset button on it you can push down. If it clicks and then works again, look for possible cooling fan problems.

Hotpoint oven won't heat above 250 degrees broiler works fine as well as the stove top


either its the oven sensor rod located at the top of the ovens cavity,or your bake element could be getting a hot spot which is when it gets a discolored spot in the element and can no longer pass sufficient current to heat the oven past 250 degrees

Electric Oven doen't heat


cdkd, there should be a TC0, on the back of the oven. Thermal cut out. You want to check to see if it is open. You will have to pull the oven out enough that you can remove the back panel cover and check it. The lower and upper oven should have one. It's a very cheap part to replace. If this TCO fails, no heat. Check this first before buying a new board. Catriver..post back.
