Display shows 'PF', and the clock resets after a power interruption.

Safety first: If you suspect wiring issues, turn off power at the breaker before inspection.

• Clear code: Press CLEAR/OFF or RESET to clear 'PF' and reprogram the clock.
• Check supply: Verify the range or wall oven is on a dedicated 240V circuit and that both breakers are fully on.
• Inspect cord and terminal block: For freestanding ranges, unplug the unit and inspect the power cord and terminal block for loose screws or burned connections. Tighten or replace damaged parts.
