Kenmore oven temperature is getting way too hot...

Hello and thank you for helping. I have a Kenmore oven model # 79090939600 bought in 2007. The temperature has been so hot that it has rendered the oven unusable. I bought an oven thermometer to see the variation between the oven setting and the actual temp. When I set it to 350F it reached 400F. When I allowed it to cool I set it to 250F and it reached 500F! Assuming this is a manageable repair I'd like to be able to handle it myself. If there are any part numbers you could throw my way that would be most appreciated as well. Thanks again for your time!

With the oven off, check the bake and broil elements for any visible damage. An element that is broken and shorted to the metal cabinet can heat constantly and cause this problem. If you see no visible damage to the element, I recommend that you

unplug the range

and check the oven temperature sensor probe using a volt/ohm meter. If you don't have a meter, you can buy one at your local Sears or hardware store for around $20. The investment will probably be worth it. You can access the oven temperature sensor probe as shown in this video:

Oven Sensor Replacement

. Here is a link for video that shows how to test that sensor using a volt/ohm meter:

Oven Sensor Testing

. The sensor should measure around 1100 ohms of resistance at room temperature. If that sensor is bad, it will need to be replaced. The part number for the sensor is 316490001. You can order that part from the

Sears PartsDirect

website. If that sensor is okay, I recommend that you check the resistance of the bake and broil elements while you have that back panel off of the range. The wiring diagram in the image below shows the wire colors on those elements. With the range still

unplugged

, pull the wires off of the element and measure the resistance. Here is a link for a video that shows how to check the resistance of a heating element in the oven:

Bake Broil Heating Element Part Testing

. The element should measure between 10 and 50 ohms. You can also check for continuity between each element terminal and the bare metal cabinet beside the element. That test should result in a reading of Ol (open load or infinite resistance). If you get a resistance reading from the test from an element lead to the metal cabinet ground, then the element will need to be replaced.

If the sensor and the elements are okay, then you will probably need to replace that clock control board in the console of the range. Here is a link for a video that shows that repair:

Range Clock Control Replacement

. The part number for that control is 316557108. Be sure that you

unplug the range

before accessing internal components.

These tips should help you diagnose and repair this oven failure. If you need more assistance, reply with additional details.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
