If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Lower oven sensor failure, loose lower sensor connector, damaged lower oven sensor harness, control board lower sensor circuit fault.

Safety first: Turn off power at the breaker.

Locate lower sensor: In double-oven models, find the sensor in the lower cavity rear wall. Remove screws and pull the sensor forward.
Measure resistance: Disconnect and test (~1080 Ω at room temperature). Replace if open or out of spec.
Check harness: Inspect wiring from the lower sensor to the control board for cuts, burns, or loose connectors. Repair or replace as needed.
Control board: If the sensor and wiring are good, replace the main control board.
