  If your Mitsubishi Electric Air Conditioner is blowing air but not cooling or heating sufficiently, consider these possibilities: * The temperature might be improperly adjusted. Check the set temperature and inlet temperature on the liquid crystal display, and adjust the button accordingly. * The filter could be filled with dust and dirt. Clean the filter. * There might be obstacles at the air inlet and outlet of the indoor and outdoor units. Remove any obstructions. * Windows and doors might be open. Ensure they are closed.

What to do if cool or warm air does not come out of my Mitsubishi Electric CITY MULTI PEFY-P18NMAU-E5 Air Conditioner?

  If cool or warm air isn't coming out of your Mitsubishi Electric Air Conditioner, it could be due to: * The restart-preventing circuit may be in operation for 3 minutes. Wait for a while, as this circuit protects the compressor and may delay its start. * The indoor unit operation was restarted during the heating and defrosting operation. Allow the unit to complete the defrosting operation before heating starts.

Why can I still hear the exhaust and motor in my Mitsubishi Electric CITY MULTI PEFY-P18NMAU-E5 Air Conditioner after it stops running?

  Karen HenryAug 23, 2025
  If you hear the exhaust and motor of your Mitsubishi Electric Air Conditioner after it stops, 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.

Why does my Mitsubishi Electric CITY MULTI PEFY-P18NMAU-E5 make intermittent exhaust and motor rotation sounds after stopping?
- J
  John SantiagoAug 28, 2025
  The intermittent exhaust and motor sounds in your Mitsubishi Electric Air Conditioner after it stops running are likely due to drained water being brought in when other indoor units are engaged in cooling operation. If the drain water is collected, the drain-up mechanism initiates a draining operation. It should stop soon. If the noise occurs more than 2-3 times in an hour, ask for repair service.

Why does warm air come out intermittently from my Mitsubishi Electric CITY MULTI PEFY-P18NMAU-E5 Air Conditioner when the thermostat is OFF or during fan operation?
- D
  Diana GomezAug 31, 2025
  If warm air comes out intermittently from your Mitsubishi Electric Air Conditioner when the thermostat is OFF or during fan operation, it is because 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.
