How to Fix / Troubleshooting
Critical safety warning: Refrigerant system repairs require specialized tools and must be performed by a licensed refrigeration technician. Do not attempt to cut or open sealed lines.
- Visual inspection: With power off, look for oily residue on refrigerant lines, evaporator, or condenser, which can indicate a leak.
- Check frost pattern: Remove the interior panel and observe the evaporator after running for 10–15 minutes. A very small frost patch or no frost at all suggests low charge.
- Professional service: If a leak or low charge is suspected, contact a qualified technician to locate the leak, repair it, evacuate, and recharge the system.
- Do not operate long-term: Running a low-charge system can damage the compressor.
