  There are several reasons why your Mitsubishi Electric Air Conditioner might not be cooling or heating sufficiently: * The temperature might be set improperly. Check the set temperature and outlet temperature on the display and adjust accordingly. * The filter may be clogged with dust and dirt. Clean the filter. * Obstacles might be blocking the air inlet and outlet of the indoor and outdoor units. Remove any obstructions. * Windows and doors might be open. Ensure they are closed.

  If warm air comes out intermittently from your Mitsubishi Electric Air Conditioner when the thermostat is off or during fan operation, it could be that when other indoor units are engaged in heating operation, the control valves are opened and closed from time to time to maintain the stability of the system. It should stop soon. If the room temperature rises uncomfortably high in a small room, stop operation.

  If cool or warm air isn't coming out of your Mitsubishi Electric Air Conditioner, it could be due to: * The restart-preventing circuit being in operation. Wait for a few minutes. * Restarting indoor unit operation during heating and defrosting. Wait for a while.

Why can I still hear the exhaust and motor after stopping my Mitsubishi Electric CITY MULTI PEFY-P36NMHU-E-OA Air Conditioner?

  Crystal LeonardAug 29, 2025
  If you hear the exhaust and motor running after you've stopped your Mitsubishi Electric Air Conditioner, it might be because: when other indoor units are engaged in cooling operation, the machine stops after running a drain-up mechanism for 3 minutes when air-cooling operation is stopped. Wait for 3 minutes.

  If you intermittently hear the exhaust and motor after stopping your Mitsubishi Electric Air Conditioner, it's possible that when other indoor units are engaged in cooling operation, drained water is being brought in. This should stop soon. If the noise occurs more than 2-3 times in an hour, ask for repair service.
