How to Fix / Troubleshooting
Safety: Unplug the unit before removing rear panels. Sealed system repairs must be done by a licensed refrigeration technician.
- Listen for compressor: With the unit plugged in and calling for cooling, listen at the back. A silent compressor suggests it is not starting; a brief hum then click suggests start failure.
- Check condenser fan: Confirm the rear fan runs. If the fan is off and the compressor is off, suspect control or power issues rather than sealed system.
- Inspect start device: Remove the compressor terminal cover and check the start relay and overload for damage. Replace with a Grundig compressor start relay and overload if faulty.
- Monitor temperature: After replacing the start device, allow several hours. If the compressor runs but there is still no cooling and the condenser stays cool, a refrigerant leak or internal blockage is likely.
- Call a technician for sealed system work: If the compressor runs continuously with no cooling, do not attempt to open the sealed system yourself.
