Possible Causes
Micro leak in evaporator or condenser, Capillary tube restriction, Internally damaged compressor valves, Factory undercharge (rare on older units)
How to Fix / Troubleshooting
Safety first: Do not attempt to cut or open any sealed refrigeration lines. Refrigerant handling requires certification.
- Check condenser and fan: Ensure condenser coils are clean and the condenser fan (if equipped) is running properly.
- Inspect frost pattern: Remove the inner rear panel and observe the evaporator after 15–20 minutes of run time. A normal system shows even frost across most of the coil. Frost only at the inlet or no frost suggests a sealed system issue.
- Listen to compressor: A very hot compressor that runs continuously with poor cooling often indicates internal wear or low refrigerant.
- Professional service: Sealed system repairs (leak detection, evacuation, recharge, compressor replacement) must be performed by an EPA-certified refrigeration technician. Weigh the cost of repair versus replacement, especially on older Haier freezers.
