How to fix the sound of exhaust and rotation of the motor after Mitsubishi Electric CITY MULTI PEFY-M20VMA-A1 Air Conditioner stops?
If you still hear the exhaust and motor running after your Mitsubishi Electric Air Conditioner stops: * **Drain-up mechanism:** 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 the sound of exhaust and rotation of the motor can be heard intermittently after stop of running Mitsubishi Electric Air Conditioner?
If you intermittently hear the exhaust and motor running after your Mitsubishi Electric Air Conditioner stops, it is because when other indoor units are engaged in cooling operation, drained water is brought in, and 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 warm air comes out intermittently when the thermostat is OFF or during fan operation of Mitsubishi Electric Air Conditioner?

It should stop soon. If the room temperature rises uncomfortably high in a small room, stop operation.
