How to Fix / Troubleshooting
Safety first: Turn off power before inspecting the door switch wiring.
- 1. Compare to manual: Check the user manual to confirm how the oven should behave when the door is opened. Many ovens keep the fan and light on.
- 2. Inspect switch wiring: Remove the door switch and verify that wires are connected to the correct terminals (COM, NO, NC) according to the wiring diagram.
- 3. Correct switch type: Ensure the installed switch matches the original Fisher & Paykel part number and contact configuration.
- 4. Replace faulty switch: If contacts are intermittent, replace the switch.
Incorrect door interlock behaviour can affect cooking performance and safety; correct any miswiring immediately.
