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
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
, 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:

. The part number for that control is 316557108. Be sure that you
unplug the range
before accessing internal components.

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:
