It is likely that the safety thermostat on the back of the lower oven is tripped. This component is circled in the portion of the wiring diagram shown in the first image below. It is Key 119 on the parts image below the wiring diagram. The location of this safety thermostat is also shown in the second image. If you want to fix this problem yourself, you can try resetting this component. There is a red button on that back that is the reset switch.

Unplug the range

and remove the lower back panel to access that thermal switch. Reset the switch and see if the lower oven will heat properly. If you cannot reset that switch, it may need to be replaced. It is part number 318004902. You can order a new safety thermostat from the

Sears PartsDirect


Unplug the range

and remove the lower back panel to access and replace this component.

If the lower oven heats properly after resetting or replacing that thermal safety switch, be sure and monitor the oven to make sure that one of the elements is not heating constantly. This would indicate that you have a problem with a stuck replay on the oven control relay board.

If the lower oven still does not heat after replacing the safety thermostat then you could have a wiring failure or a bad control board that is preventing the lower oven from heating.

If you need more help, let us know.

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:
