Sensor wiring shorted to hot conductor, melted harness near oven cavity, failed control board sensor circuit

Warning: High temperatures can damage wiring. Ensure the oven is cool and power is off before inspection.

Inspect harness near cavity: Remove rear panel and inspect the sensor harness where it passes near the oven liner. Look for melted insulation or contact with metal edges.
