Possible Causes
Refrigerant leak in evaporator or condenser, Restricted capillary tube, Failed compressor, Non-condensable gases in system from prior improper service
How to Fix / Troubleshooting
Critical safety: Sealed system work involves refrigerant and requires EPA-certified technicians and specialized tools. Do not attempt to open the sealed system yourself.
- 1. Verify compressor operation: Listen and feel for the compressor running. If it is silent or only clicks, test the start relay and overload as described in compressor fault procedures.
- 2. Check temperature of lines: With the compressor running, carefully feel the suction and discharge lines. If both are at or near room temperature after 10–15 minutes, the system may be low on refrigerant or the compressor is not pumping.
- 3. Inspect for oil stains: Look around joints, the evaporator, and condenser for oily residue, which can indicate a refrigerant leak.
- 4. Clean condenser and ensure airflow: Confirm that the condenser fan runs and coils are clean. Poor airflow can mimic sealed system issues.
- 5. Call a professional: If the compressor runs but there is no cooling, contact a licensed refrigeration technician to perform a leak check, pressure test, and repair/charge the system as needed.
