How to restart McQuay MWM009J after power failure?
If your McQuay Air Conditioner doesn't automatically turn back on after a power outage, the auto-restart function may not be working. Try manually turning the unit on using the wireless or wired controller.
Why is my McQuay MWM009J not blowing warm air?
If your McQuay Air Conditioner isn't emitting warm air during the heating cycle, it might be in defrost mode. The heating operation should resume automatically once the defrost cycle is complete.
What to do if McQuay MWM009J compressor doesn't start?
If the compressor in your McQuay Air Conditioner doesn't start immediately after turning the unit on, it might be due to a built-in protection against frequent starting. Wait 3 to 4 minutes; the compressor should start on its own.
Why does my McQuay Air Conditioner compressor run continuously?
If the compressor in your McQuay Air Conditioner is running constantly, it could be due to a dirty air filter. Try cleaning it. Alternatively, if you are cooling, the temperature setting might be too low; set it higher. If you are heating, the temperature setting might be too high; try setting a lower temperature.
Why is there condensation on my McQuay MWM009J Air Conditioner?
Condensation on the front grille of your McQuay Air Conditioner's indoor unit is likely due to air humidity after prolonged use. Try increasing the temperature setting and running the unit at a high fan speed.
