Error Codes (undefined): Troubleshooting, Fixes & Prevention Tips explained below.

What Does the EC Code Mean?❓

The EC code indicates that the air conditioner has sensed a refrigerant leak. This error triggers the system to shut down cooling to protect the compressor and other parts from damage caused by low refrigerant levels. The system requires leak repair and refrigerant recharge before resuming normal operation.
