  If your Mitsubishi Electric Air Conditioner does not cool or heat enough, make sure that you have properly set the temperature. Check the inlet temperature on the liquid crystal display and adjust the settings as needed. Also, ensure that the filter is clean, and there are no obstructions blocking the air inlet or outlet of the indoor and outdoor units. Finally, close any open windows and doors.

  If your Mitsubishi Electric Air Conditioner doesn't run, first ensure that there isn't a power failure. If there was a power failure, press the [ON/OFF] button. Then, check if the power supply is turned on and that the fuse is intact. Also, check the earth leakage breaker and put it in if it's gone.

  If your Mitsubishi Electric Air Conditioner runs briefly and then stops, check for any obstructions at the air inlet and outlet of both the indoor and outdoor units and remove them. Also, clean the filter if it is filled with dust and dirt, and then rerun the system.

Why is no cool or warm air coming out of my Mitsubishi Electric CITY MULTI PEFY-P12NMAU-E3 Air Conditioner?

  If cool or warm air does not come out of your Mitsubishi Electric Air Conditioner, it might be due to the restart-preventing circuit, which takes about 3 minutes to complete its cycle. Please wait for a while. Also, if the indoor unit operation was restarted during the heating and defrosting operation, wait for a while, as heating operation starts after defrosting is completed.
