What to do if Mitsubishi Air Conditioner remote displays an error code?
- JJames WilsonAug 14, 2025
If your Mitsubishi Air Conditioner remote controller displays an error code, it indicates that the self-diagnostic function is running to preserve the unit. Do not attempt to make repairs yourself. Turn the main switch off and contact the dealer from whom you bought the air conditioner, providing the unit name and the information displayed on the remote controller.
