Error Code
The E0 error code on your Actron Air conditioning unit indicates a communication failure between the indoor and outdoor units. This prevents the system from functioning properly.
If the wiring between the indoor and outdoor units is loose or damaged, it can cause a communication breakdown.
The Printed Circuit Board (PCB) in either the indoor or outdoor unit may be malfunctioning.
Voltage fluctuations or power surges can interfere with the communication between units.
Turn off the air conditioner for 5–10 minutes, then turn it back on to reset the communication.
Check the wiring between the indoor and outdoor units for any loose or damaged connections.
If communication issues persist, the PCB may need to be inspected and replaced by a technician.
