REPLACED UPPER HEATING ELEMENT AND THE TEMPERATURE SENSOR. OVEN AND BROILER STILL NOT HEATING UP.

Replace the heating mechanism or control board

Hello Billy;

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

First, your broiler is not connected to your oven thermocouple (Temperature sensor). When you turn on your broiler full load amps go into the broiler element with no adjustment.

There are only three components that control your oven operation:

1.) Heater Element - Inspect your heating element for cracks, sparking or corrosion on the two contacts on the back wall.

2.) Thermocouple - This is a temperature sensor inside your oven. It is about the diameter of a coat hanger wire. Either it comes straight out of the back upper wall or is mounted on the back wall.
It is disconnected and removed from the upper back of the oven.
You should get a meter reading of 1000-1100 Ohms if the component is good.

3.) Oven Control - The control communicates with the thermocouple and increases or decreases the amps to the oven heating element. If the thermocouple is good then the oven control needs to be replaced.

If in unsure, replace them both.

Recently, I replace a digital oven control for a friend. Sears wanted $256.00 for the control. I purchased a remanufactured oven control over the internet for $30.00.

Get the oven model number off your oven. It is on a metal tag on the face of the oven after you open the door.

Go into the following website. Put in your oven model number (on the left). You will get diagrams and parts part numbers. Record these numbers for the above components. Put the part number in your computer search engine and search best price.

CAUTION: If you replace a electrical control board GROUND YOURSELF by touching something that is bare metal. Static electricity will knock out a control board.

Test the temperature sensor in the oven to make sure it ohm's out between 1060-1100 ohms. Here is the sensor to order in case it is bad.

Are you having any issues at all with the display at all? Did this start out of the blue or did you have a power outage or anything else?

The top element should come on when Broiler is selected. If both ovens have a broiler mode, then look for something failed in the circuit for the broiler heating elements (it's unlikely both broiler elements would fail together.). If there is only 1 oven with a broiler, look for a failed broiler element.

It won't bake or broilIf neither the bake nor the broiler heating elements heat, but the range burners still work, the clock may be set for a timed or self-cleaning cycle. Check to be sure the clock buttons and knobs are set properly. If your clock has a knob that says "push for man(ual)", push the knob in and try the baking and broiling elements again. If it still does not operate properly, you probably have a defect in the thermostat, selector switch, or common wiring.

If the oven does not have a separate bake/broil/etc. selector switch, the problem may be with the thermostat. But it's not easy to check the selector switch or thermostat for proper operation. If you suspect a problem in this area, call a qualified appliance repair technician.

• When the food you're baking is done on top but not on the bottom--or when baking just takes far too long to finish--the bake element may be burned out.


You may get fooled into thinking it's working, because the oven is hot inside. But many electric ovens use the broil element, too, during the preheat and bake cycles. So the food may be getting heated only by the broil element, which causes poor baking results.

If the bake element is burned out, replacing it should solve the problem. Otherwise, you need to further troubleshoot the oven's electrical system to locate the defective wire or component.


• When the temperature is consistent but too high or too low, it could be one of several different things. First check to see if the thermostat sensing bulb has come loose from its holder. It could be lying on the floor of the oven or resting on the heating element. This would cause the oven to not heat correctly.


If the thermostat bulb is not dislodged, it's likely that the thermostat or sensor is either mis-calibrated or defective.

Electronic ovens with a digital display use a sensor to monitor oven temperature. To solve temperature problems for these models, you may need to replace the sensor. On some digital-display models, you can calibrate the temperature using the key pad. See your operator's manual for details.

Ovens without a digital display often use a mechanical system for controlling temperature. On many of these units, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat.

If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem.

It won't broil Usually, when an oven won't broil, it's because the broiler element is burned out. The broiler element in an electric oven is the black, pencil-thick tube at the top of the oven. When the broiler is on, 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.

The broiler element on the top of the oven comes on during the preheat cycle to speed things up and then only the lower element keeps the temperature steady. One of those elements is bad, probably the broiler. Try using the broiler and see if it works. If not, you need to disconnect the elements from the oven and check them with an ohm meter. If gthe elements check out ok, then it must be the temperature sensor/thermostat.

If all your connections are solid then your controller is defective. Did you get any faults before changing the element? Does the broil (one at the top of the oven) work?

It's either the switch that supplys power to the broiler element or it's the element itself (probably the element itself). I'd go after that first as it's not that expensive.

It's not a thermostat because if it was, the bake element wouldn't work either. The broiler element is not supposed to come on except when in the broil mode or cleaning mode.

Shaffy, When baking only the bake element should heat. When broiling only the broil element (upper) should heat. Your oven is a Kitchenaid, you have a 5 year warranty on any electronic element or control board. You may have a temperature sensor that is not working right. The oven just might need to be calibrated, the instructions would be in your owners manual. Your bake element might be failing, it would have to be ohmed out. You also need to verify that the bake element is getting 240V. when turned on. Catriver...post back
