Possible Causes

Dirty condenser coil, failed condenser fan motor, high ambient temperature, refrigerant overcharge or restriction, discharge temperature sensor fault

How to Fix / Troubleshooting

Safety: Disconnect power. Components near the compressor and discharge line can be very hot.

  • Clean condenser: Thoroughly clean the condenser coil with a brush and vacuum. Ensure nothing blocks airflow around the unit.
  • Check condenser fan: Verify the fan blade spins freely and the motor runs when the compressor is on. Replace the condenser fan motor if it does not run.
  • Verify installation: Ensure the unit has adequate clearance per Scotsman’s installation manual and is not installed in a confined, unventilated space.
  • Inspect discharge sensor: If equipped with a discharge line thermistor, check that it is properly attached and not damaged. Test resistance and replace if out of spec.
  • Refrigeration issues: If the code persists after cleaning and fan repair, a refrigeration problem (overcharge, restriction, non-condensables) may exist and must be addressed by a certified technician.
