Why cool or warm air does not come out of my Mitsubishi Electric Air Conditioner?
- H
  Heather CrawfordAug 19, 2025
  If your Mitsubishi Electric Air Conditioner is not emitting cool or warm air, it could be because: * The restart-preventing circuit is 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 heating and defrosting. Allow the unit to complete the defrosting operation before heating begins.

  Philip HawkinsAug 23, 2025
  If you hear exhaust sounds and motor rotation after your Mitsubishi Electric Air Conditioner stops, it's likely 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 my Mitsubishi Electric Air Conditioner makes intermittent noise after being turned off?
- R
  Rachel MarshallAug 27, 2025
  The intermittent noise from your Mitsubishi Electric Air Conditioner after it's turned off is likely due to drained water being processed when other indoor units are engaged in cooling operation. 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 from my Mitsubishi Electric TRANE TPEFYP018MA144A during fan operation?
- C
  Cheryl WalterAug 31, 2025
  The intermittent warm air from your Mitsubishi Electric Air Conditioner, even when the thermostat is off or during fan operation, happens 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.
