Safety: Disconnect power before accessing elements or sensors.

Check lower bake element: Inspect the lower oven floor element for visible damage. Test for continuity; replace if open.
Test lower oven sensor: Measure resistance of the lower oven temperature sensor at room temperature. Replace if out of spec.
Inspect harness: Check wiring from the control board to the lower oven components for damage or loose connectors.
