Error codes are a code used to identify where something may need to be repaired or isn’t functioning as it should in your air conditioning system. Each code has a different meaning and when defined the codes can indicate the source of the problem, allowing technicians to approach it directly.
Below are the error codes for Actron Air units with their matching explanation.
Restarting the system will delete the air conditioner’s on board memory. It’s not always successful but it is worth a try before spending money on a service call.
Re-start your system by separating your air conditioning system from its power supply. Unplug it from a power point, turn off the isolator next to the outdoor unit or shut down your house’s power from the electrical board. Then leave it for 15 – 30 minutes.
Having a professional look into your error is safe and will ensure you don’t inadvertently cause further damage to your AC unit.
0: Cooling Mode
1: Heating Mode
2: Heating compressor run time >20mins
3: Heating Defrost
4: LOW speed flashes every 30s: Over Heat or Anti-Freeze Protection mode (Reduced Capacity Mode)
5: Heating mode – indoor coil pre-heat
E6: Fault discharge temperature
E7: Fault outdoor coil sensor (open or closed circuit)
