  If your McQuay Air Conditioner is running but not cooling effectively, several factors could be the cause. First, make sure the thermostat isn't set too high; try resetting it. Ensure all doors and windows are completely closed. If these steps don't help, there might be an obstruction blocking the unit's inlet or outlet; remove any objects you find. For issues such as a dirty condenser coil or insufficient refrigerant, it is best to contact your local dealer.

  If neither the fan nor the compressor is working on your McQuay Air Conditioner, there are a few things you can check. First, there may be a power failure; the unit should resume operation when the power supply is restored. Also, the starter may have tripped; try resetting it. Finally, inspect the fuse in the power switch or operating unit and replace it if it's blown.

  If the fan on your McQuay Air Conditioner isn't working, start by checking the power supply. If the power supply is fine, the issue might be a faulty fan capacitor or fan motor, in which case you should contact your local dealer. Another potential cause is a faulty switch, which would need to be changed.

  If the fan on your McQuay Air Conditioner is working, but the compressor isn't, there are a few potential reasons. First, the thermostat setting might be too high; try resetting it. It's also possible that the dual pressure control has tripped; in this case, reset the pressure control. For compressor or compressor contractor issues, contact your local dealer.
