Possible Causes

Recent power outage, Loose power cord connection, Tripped breaker or weak circuit, Faulty terminal block at rear of range

How to Fix / Troubleshooting

Safety First: Turn off the breaker before inspecting the power connections at the rear of the range.

  • Confirm household power: Check your home's breaker panel for a tripped breaker. Reset if necessary and ensure the oven is on a dedicated 240V circuit.
  • Inspect power cord and outlet: Pull the range forward carefully and verify that the power cord is fully seated in the outlet and not damaged.
  • Check terminal block: Remove the rear cover to access the terminal block where the cord connects. Look for burnt wires, loose screws, or melted plastic. Tighten connections and replace any damaged parts.
  • Clear PF code: Press Cancel or Clear to remove the PF message, then reset the clock and test a bake cycle.
  • Monitor for recurrence: If PF appears frequently without actual outages, have an electrician check the circuit and consider replacing the electronic oven control board if all wiring is sound.
