Possible Causes
Loss of refrigerant due to leak, Failed compressor, Blocked capillary tube or filter-drier, Faulty compressor start relay or overload
How to Fix / Troubleshooting
Safety first: Unplug the unit before touching the compressor or electrical parts.
- 1. Check compressor operation: Plug in and start a cycle. Listen for the compressor humming. If it never starts, inspect the start relay and overload protector.
- 2. Feel condenser and compressor: After a few minutes, the compressor and condenser should become warm. If both stay cold, the compressor may not be running.
- 3. Inspect for leaks: Look for oily spots on copper tubing or around joints, indicating refrigerant loss.
- 4. Evaluate evaporator: If the compressor runs but the evaporator never gets cold, the system may be low on refrigerant or blocked internally.
- 5. Seek professional service: Refrigeration repairs (leak detection, recharging, compressor replacement) must be done by a certified technician.
Warning: Do not attempt to pierce or solder refrigerant lines yourself; this is hazardous and may be illegal without certification.
