To Next PageTo Next PageWhat to do if my Mitsubishi Electric PEFY-P24NMHU-E does not run?
If your Mitsubishi Electric Air Conditioner isn't running, it could be due to a power failure. After power is restored, press the [ON/OFF] button. Alternatively, ensure the power supply is turned ON, and check if the fuse in the power supply needs replacement or if the earth leakage breaker needs to be reset.
Why is my Mitsubishi Electric PEFY-P24NMHU-E Air Conditioner blowing air but not cooling enough?
If your Mitsubishi Electric Air Conditioner is blowing air but not cooling or heating sufficiently, first check the set temperature and inlet temperature on the display. Adjust the temperature as needed. Also, make sure to clean the filter if it's filled with dust and dirt. Remove any obstacles blocking the air inlet and outlet of the indoor and outdoor units, and ensure windows and doors are closed.
What to do if my Mitsubishi Electric PEFY-P24NMHU-E runs briefly, but soon stops?
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; remove any that you find. Also, clean the filter if it's dirty or dusty before restarting the unit.
Why does warm air come out intermittently from my Mitsubishi Electric Air Conditioner when the thermostat is OFF?
If warm air comes out intermittently from your Mitsubishi Electric Air Conditioner when the thermostat is OFF or during fan operation, it's because the control valves are opening and closing to maintain system stability when other indoor units are engaged in heating. This should stop soon. If the room temperature rises uncomfortably high, stop operation.
Why is there no cool or warm air coming from my Mitsubishi Electric Air Conditioner?
If no cool or warm air is coming out of your Mitsubishi Electric Air Conditioner, it might be because the restart-preventing circuit is in operation, which can last up to 3 minutes to protect the compressor. If you started the indoor unit during heating and defrosting, wait for the heating operation to begin after defrosting is complete.
Why can I still hear the motor after my Mitsubishi Electric Air Conditioner stops?
If you can still hear the exhaust and motor running after your Mitsubishi Electric Air Conditioner stops, it's likely because the drain-up mechanism is running for 3 minutes after air-cooling operation is stopped, especially if other indoor units are engaged in cooling operation. Please wait for 3 minutes.
Why does my Mitsubishi Electric Air Conditioner make intermittent noises after it stops?
If you intermittently hear the exhaust and motor running after your Mitsubishi Electric Air Conditioner has stopped, it's likely due to the drain-up mechanism initiating a draining operation when drained water is brought in from other indoor units engaged in cooling. This should stop soon. However, if this occurs more than 2-3 times in an hour, ask for repair service.
