How to Fix / Troubleshooting
Safety first: Turn off power at the breaker for at least 5 minutes before attempting any reset.
- Hard reset: After 5–10 minutes with power off, restore power and check if the error clears. Try basic functions (Bake, Fan Bake) without using timers or special modes.
- Check for moisture/cleaning damage: If the error appeared after heavy cleaning or liquid spill, inspect the control panel area for moisture. Allow the unit to dry for 24 hours with power off.
- Inspect wiring: Remove the control panel (if accessible) and check all harness connectors to the control board and display module. Reseat each connector firmly.
- If F5 persists: The electronic oven control board is likely defective. Replacement requires transferring wires one by one from the old board to the new Fisher & Paykel control, matching connector labels.
- Technician recommended: Because this involves live-voltage circuits and programming, consider a qualified Fisher & Paykel technician for control replacement.
