Possible Causes
How to Fix / Troubleshooting
Safety: Disconnect power before cleaning or accessing the condenser area.
User-level steps:
- 1. Clean the condenser coil: Remove the front grille. Use a soft brush and vacuum to remove dust and lint from the condenser fins. Take care not to bend the fins.
- 2. Check airflow: Ensure nothing is blocking the front or rear of the unit. Verify that installation clearances meet Sub-Zero specifications.
- 3. Verify condenser fan operation: Restore power and observe the condenser fan during operation. If the compressor runs but the fan does not, disconnect power and inspect the fan blades for obstructions. If clear, the fan motor may be defective and require replacement.
Technician-only steps: Diagnosing high head pressure due to refrigerant overcharge, non-condensables, or internal restrictions requires gauges and specialized tools. Contact a Sub-Zero authorized service provider for sealed system work.
