Control board or electronic control failure

How to Identify: No display or response at all after confirming external power; internal electronics are unresponsive.

Part: Control board / main PCB

Thermal cut-out / internal safety device triggered or failed

How to Identify: Oven remains completely dead after overheating event or power surge; may occur after usage shortly before failure.

Part: Thermal cut-out / safety thermostat
