Possible Causes
Failed relay on PCB controlling lamp or accessory, Shorted lamp holder, Damaged wiring to accessory (e.g. meat probe socket), PCB track damage
How to Fix / Troubleshooting
Safety first: Isolate the oven from mains power before accessing internal wiring or the lamp holder.
Step-by-step checks:
- 1. Check oven lamp: Remove the glass cover and lamp. Inspect for a blown filament. Replace with a high-temperature Zanussi-compatible oven bulb.
- 2. Inspect lamp holder: Look for signs of arcing or burning around the lamp holder. Replace if damaged.
- 3. Check wiring: Trace the wiring from the lamp or accessory back to the PCB. Repair any burnt or broken wires.
- 4. Inspect PCB relay: On the control board, locate the relay controlling the lamp/accessory. If it is burnt or cracked, the board will need replacement.
Warning: Use only oven-rated bulbs; standard bulbs cannot withstand the temperature.
