Possible Causes

Failed lower oven temperature sensor, Open or shorted lower sensor wiring, Loose connector at lower oven control

Safety first: Turn off power at the breaker.

Identify lower sensor: On double wall ovens, locate the lower cavity sensor on the back wall of the lower oven.
Test sensor: Remove the sensor, disconnect it, and measure resistance at room temperature (~1080 Ω). Replace if out of spec.
Check harness: Inspect the wiring from the lower sensor to the control board for damage or loose connections. Repair as needed.
