Frigidaire F10: Oven Runaway Temperature

Safety first: F10 + oven heating = turn off the circuit breaker. Not just the oven switch.

Diagnostic order:

RTD sensor — Should read 1,080Ω at room temp. Part 316217002 ($18–35)

Wiring harness — Corroded connectors near oven cavity cause false F10s. Clean and reseat first.

Control board relay — Stuck closed = continuous heating. Look for char marks near relay on board. ($175–275 + labor)
