Possible Causes
Low refrigerant charge due to leak, Blocked or dirty condenser coil, Failed compressor, Faulty pressure or temperature sensor indicating cooling failure
How to Fix / Troubleshooting
Safety: Unplug the unit. Refrigerant system repairs must be done by a licensed technician.
Steps to address EC:
- Basic cleaning: Clean the air filter and both evaporator and condenser coils to ensure proper airflow.
- Check fan operation: Confirm that the fan runs at full speed when the unit is on. A failed fan can cause EC by preventing proper heat exchange.
- Listen for compressor: When the unit calls for cooling, listen for the compressor starting. A silent compressor with EC suggests a compressor or control issue.
- Inspect for oil stains: Look around refrigerant tubing and joints for oily residue, which can indicate a refrigerant leak.
- Professional service: If EC persists after cleaning and verifying fan operation, contact a certified HVAC/appliance technician. They can check refrigerant pressures, locate leaks, and test the compressor.
Warning: Do not attempt to cut or open refrigerant lines yourself.
