Why cool or warm air does not come out of my Mitsubishi Electric Air Conditioner?
- M
  Martha LloydAug 16, 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.

Why does my Mitsubishi Electric TRANE TPEFYP MA144A make noise after stopping?
- S
  Sandra CookAug 20, 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?
- C
  Cynthia FlemingAug 25, 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 Air Conditioner during fan operation?
- M
  Melissa JacksonAug 28, 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.
