Frigidaire Oven: self-activating oven element

Professional Repair Guide

What is this symptom?

Experiencing a Frigidaire oven where the heating element activates unexpectedly, even when the oven is turned off? This self-activating oven element can pose safety risks. The issue may stem from a faulty control board, damaged wiring, or a malfunctioning temperature sensor. It's crucial to address this problem promptly to ensure safe operation.

Urgency: High

Important Tips for Frigidaire Models

  • Some models may have a programmable timer or delay-start feature that can be mistaken for spontaneous activation; verify and disable scheduled settings first.

Possible Causes

Faulty electronic control board or stuck relay

How to Identify: Oven element activates randomly without input, erratic display behavior, or relay clicking sound before activation.

Part: Oven control board / relay

Shorted or damaged wiring harness or connections

How to Identify: Visual inspection shows melted insulation, pinched or loose wires; random activation correlates with physical wiring issues.

Part: Internal wiring harness

Faulty temperature sensor or thermostat misreading

How to Identify: Sensor reads incorrect temps leading control board to erroneously power heating element; may also display unusual temperature behavior.

Part: Temperature sensor / thermostat

Accidental or malfunctioning timer/delayed start feature

How to Identify: Check if scheduled timer/delay start settings are active; if timer malfunctions, oven initiates heating cycle at set times.

Part: User interface / timer
