Possible Causes
Slow refrigerant leak in evaporator or condenser, Partially blocked capillary tube, Weak compressor
How to Fix / Troubleshooting
Safety: Do not attempt to open the sealed system yourself. Unplug before removing covers.
Steps:
- Observe coil frost pattern: With the cover removed and unit running, check the evaporator. Frost only on a small section or none at all suggests low charge or restriction.
- Listen to compressor: A noisy or very hot compressor may be failing.
- Confirm airflow: Ensure fan and filters are clean to rule out airflow issues.
- Professional repair: If airflow is good but performance is poor and frost pattern is abnormal, contact a refrigeration technician to leak‑test, repair, evacuate, and recharge the system.
