Possible Causes
Blown internal fuse on power board, Faulty power supply module on main control board, Loose mains terminal block connection, Shorted component causing fuse to blow
How to Fix / Troubleshooting
Safety: This involves live mains circuits. If you are not trained, contact a professional. Always disconnect power before opening the appliance.
Basic checks:
- Verify that the wall outlet or circuit breaker is supplying power.
- Pull the oven out and remove the top or rear cover to access the mains terminal block. Check for loose screws or burned terminals and tighten/replace as needed.
- Locate the internal fuse on the power input or main control board. Test it with a multimeter. If blown, investigate for shorts (burned components, pinched wires) before replacing.
- If the fuse blows again immediately, there is likely a shorted component on the main control board or in the wiring, which should be diagnosed by a technician.
