Part: Main gas supply or pressure regulator shut‑off valve

Faulty temperature sensor

How to Identify: Oven turns on but fails to maintain or reach temperature; inaccurate temperature readings.

Part: Temperature sensor

Control board or electronic failure

How to Identify: No response from buttons, error codes, or intermittent operation; other components appear intact.

Part: Oven control board

Loose or damaged wiring

How to Identify: Visible burnt or broken wires upon inspection; intermittent oven operation.
