Ice maker runs but produces no ice; evaporator does not get cold.
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. This requires specialized tools and certification.
Basic checks:
- Verify fan operation: Ensure the condenser fan motor is running and blowing air across the condenser coil.
- Check condenser cleanliness: Clean dust and lint from the condenser fins to improve heat rejection.
- Feel evaporator: After 10–15 minutes of operation, carefully touch the metal evaporator fingers. They should be very cold and may frost lightly. If they remain at room temperature, there is a cooling problem.
- Listen to compressor: Confirm the compressor is running steadily (a low humming sound) and not clicking on and off.
- Observe for oil stains: Oil spots around tubing joints can indicate a refrigerant leak.
Next steps: If the compressor runs but there is no cooling, the unit likely has a sealed system issue (leak, restriction, or weak compressor). This is not user‑serviceable.
When to call a professional: Contact a refrigeration technician or Silonn service center for sealed system diagnosis and repair. In many countertop ice makers, sealed system repairs may not be economical compared to replacement.
