How to Fix / Troubleshooting
Safety first: Refrigerant handling must be done by a licensed technician. Do not attempt to recharge or open the system yourself.
- Step 1 – Visual inspection:
- Look for oily spots on coils and tubing, which indicate refrigerant leaks.
- Step 2 – Stop using the unit:
- Running with low refrigerant can overheat the compressor.
- Step 3 – Call a professional:
- Have a technician perform leak detection, repair the leak, evacuate, and recharge with the correct refrigerant type and amount.
- The Evaporator Coil or Condenser Coil may need replacement if leaking.
After proper repair and recharge, EC should clear automatically.
