Possible Causes
Refrigerant leak in evaporator or condenser, Blocked capillary tube or expansion device, Severely undercharged system, Internal compressor failure
How to Fix / Troubleshooting
Safety: Do not attempt to open the sealed refrigeration system yourself. Refrigerant handling requires certification.
- Check coil temperatures: With the unit running, carefully feel near (not directly on) the evaporator and condenser coils. If both are near room temperature, refrigerant flow may be lost.
- Inspect for oil stains: Look for oily residue on tubing joints, coils, or around the compressor, which can indicate a leak.
- Confirm airflow: Ensure fans are running and filters/coils are clean to rule out airflow issues.
- Professional service: If a refrigerant problem is suspected, contact an EPA-certified technician. They can locate leaks, repair them, evacuate, and recharge the system to Black+Decker specifications.
