Possible Causes
Refrigerant leak in coils or tubing, Blocked capillary tube or expansion device, Severely dirty condenser causing high pressure, Non-condensable gases in system
How to Fix / Troubleshooting
Safety: The refrigerant circuit is sealed and requires specialized tools and certification to service. Do not attempt to open the system yourself.
Steps:
- 1. Basic checks: Confirm the unit is in COOL mode, set to a low temperature, and that both fans and compressor are running.
- 2. Coil temperatures: Carefully feel (without touching sharp fins) the inlet and outlet of the evaporator and condenser coils. If both are near room temperature, refrigerant flow may be lost.
- 3. Visual inspection: Look for oily residue on coils or tubing, which can indicate a refrigerant leak.
- 4. Professional service: If a leak or sealed system issue is suspected, contact a licensed HVAC technician. On many compact Danby units, sealed system repair may exceed replacement cost.
