What to do if my McQuay MWM Air Conditioner is not cooling enough?
If your McQuay Air Conditioner isn't cooling sufficiently, it might be due to a dirty indoor or outdoor coil. Try cleaning the coil. Also check for any obstructions at the air inlet or outlet of the indoor or outdoor unit and remove them. It could also be caused by a refrigerant short charge or leakage, in which case you should add refrigerant and repair the leakage.
How to fix a McQuay MWM that won't turn on (no cooling/heating)?
If your McQuay Air Conditioner fails to start, it could be due to a faulty contactor, contacts or motor. Try changing the contactor or the contacts. You might also need to repair or change the motor.
Why McQuay Air Conditioner shows high side low side?
If your McQuay Air Conditioner is showing a high side low side issue, it could be due to: * An undercharge of refrigerant. * Refrigerant leakage. * A clogged or dirty air filter in the indoor unit. * A locked indoor fan (during cooling). * A defective defrost control causing outdoor coil freeze-up (during heating). * A locked outdoor fan (during heating).
