Possible Causes
Blown internal fuse on main PCB, Faulty mains power cord, Defective on/off switch or control panel, Tripped household circuit breaker or faulty outlet
How to Fix / Troubleshooting
Safety first: Before opening any panels, unplug the refrigerator and verify the outlet is de-energized.
Steps:
- 1. Check the outlet: Plug in another appliance to confirm the socket has power. Reset any tripped breakers or RCDs.
- 2. Inspect the power cord: Look for cuts, burns, or crushed sections. Replace the cord if damaged.
- 3. Try the power button: Some De Dietrich models have a soft power button on the control panel. Press and hold for several seconds to turn on.
- 4. Access the main PCB: Remove the rear cover and inspect the board for a blown fuse or burnt components. Replace the fuse only with the same type and rating, and only if you can identify and correct the cause.
- 5. If the new fuse blows immediately or the board is visibly damaged: The PCB must be replaced by a technician.
