Top Oven Stops Working

Your wiring diagram and parts schematics are here in the link below. Normally the bottom element does glow read hot after a couple of minutes. Broil elements last a lot longer because they aren't used as much. There is only one Control Board. If I was guessing, I would say the temperature sensor is at fault. Elements either work, or they don't, but you can easily test continuity with a meter. Many parts are discontinued.

Fan would need replaced, they can't be fixed

Is it continues to heat up then its working fine...if it continues to heat pass 400 then your have a thermostat problem and the oven is out of control. I do believe that the display is not an actual reading of the oven temperature, instead it is a reading of where the operator has set the temperature to . I have yet to see an oven with a actual reading temperature display.

time for a new element

Usually a safety thermostat, but it can also be wiring, a control board, or a dlb relay. Call Kitchen Aid warrantee service on this, as some of the electonics have a longer warrantee on them. Good Luck, Appliance Specialists.

Usually, when an oven won't heat, it's because the bake element is burned out. The bake element is the black, pencil- thick tube at the bottom of the oven. When the oven heats, the element glows red. This element has an expected life-span of several years. It may last for only one; it may last for many more. When the element burns out, you need to replace it.

I suspect a heating element in the oven has burned out. Some ovens have 2 heating elements, one on the bottom for baking and one on the top for broiling. If this is the case, you can try setting the oven on broil and see if the top element gets hot. Usually the bottom element fails first because food gets dripped on it. In most cases you can unplug the old heating element by just pulling on it and plug the new one just as easily. You can check the resistance of the heating element with an ohm meter. If it's burned out the resistance will be very high, probably greater than a mega ohm. In some cases you will need to take the back off the oven to replace the heating element. Just make sure the oven is unplugged and cool when you start working on it.

Check your main panel. If you ran it for a long time with the door open, the elements never reached their shutoff temperature. Quite possibly, you burned them out.

Dear customer,
i recommend u to try the following routine to sort out this problem

Check timer and clock settings

Reseat the element

Test the element

Test the element connectors

Test the oven temperature control

Test the oven selector control

Recalibrate the temperature control

hope u find this useful. thank you.

Sir, I think the top oelement is for broiling ONLY. It should not turn on when baking. The clicking may be the oven heating up.
How far apart were the oven temp instrument and the digital?
Don't expect them to match...they are inaccurate.

1. Heat water until it boils. Place digital therm in boiling water until it comes up to 212deg. If it is not at 212 in boiling water, record the error.(this gives a rough calibration to the digital)
2 Turn on oven, set to 350 deg, place digital therm on rack. Wait until oven reaches 350 (on stove) and read the digital. Note the difference between the two
