Possible Causes
Door switch shorting to chassis, damaged wiring in the door area, lamp circuit short when the door opens, pinched harness near the hinge
How to Fix / Troubleshooting
Safety first: Do not continue resetting a tripping RCD. Disconnect the oven and verify its insulation.
- Observe trigger: Confirm that the trip occurs exactly when the door moves. This points to door-related circuits.
- Inspect door switch: Access the switch and check for a cracked housing or exposed terminals touching metal. Replace if damaged.
- Check lamp wiring: Since the lamp often turns on with the door, inspect the lamp holder and its wiring for shorts to the cavity.
- Inspect hinge area: Look for pinched or cut wires near the hinges where movement occurs. Repair with high-temperature insulated wire.
Warning: Earth faults in moving parts can be intermittent and dangerous; thorough inspection is essential.
