What to do if operation lamp is blinking near the receiver on Mitsubishi Electric indoor unit?
- EEvan YoungSep 23, 2025
If the operation lamp near the receiver for the IR wireless remote controller on the indoor unit is blinking, it indicates that the self-diagnosis function has been activated to protect the air conditioner. Do not attempt to repair this equipment yourself. Turn off the power switch immediately and consult your dealer. Be sure to provide the dealer with the model name.
