790.79383400 kenmore dual fuel oven won't heat up


The oven is probably heating to 100 degrees because of the convection heating element. Based on your description, you could have a voltage supply problem or a failed electronic oven control board (part 316418752 -- also called clock timer).

I recommend that you check the house circuit breakers or house fuses for the range first. You could have lost the L2 power supply to the range (traced in red on the wiring diagram in the first image). If the house circuit breakers or fuses for the range are okay, I recommend that you check the voltage at the range outlet. The diagram in the second image shows the voltage that you should measure at that outlet. NOTE: You should only check that live outlet voltage if you are completely confident in your technical ability to safely measure it .

If the outlet voltage is okay, then you will probably need to replace that electronic oven control board to fix this problem. You could have a wiring failure with the L2 IN wire traced in red. If not, then the relay for the L2 OUT circuit (traced in orange) has probably failed on that control board.

You can order the new control board (part 316418752) from the Sears PartsDirect website.

Be sure that you unplug the range before accessing internal components and replacing that board.

I hope that this information helps. 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: Sears Home Services .
