Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Safety first: Do not attempt to open the sealed refrigeration system yourself. Refrigerant handling must be done by a certified technician.
Basic checks you can do:
- Check condenser cleanliness: Unplug the unit and remove the lower front or rear grille. Use a soft brush and vacuum to clean the condenser coil. Poor airflow can mimic low charge symptoms.
- Verify condenser fan operation: Plug the unit back in and observe the condenser fan motor. It should run whenever the compressor runs. If the fan is not spinning, the system will overheat and not cool properly.
- Inspect evaporator plate: After 15–20 minutes of operation, open the ice-making compartment and check the evaporator plate. There should be an even frost pattern. If only a small section frosts or no frost appears, the system may be undercharged or restricted.
- Listen for compressor noise: A very quiet or unusually noisy compressor can indicate internal failure.
Next steps: If cleaning the condenser and confirming fan operation does not restore ice production, the issue is likely within the sealed system (refrigerant, capillary, filter-drier, or compressor). Contact an authorized De Dietrich service center for sealed system diagnostics and repair.
