McQuay Air conditioner not cooling 
If the air filter is clogged, air cannot flow properly through the air conditioner. This greatly reduces the cooling capacity of the air conditioner. In addition, if the air filter is clogged, the evaporator coils will frost over. To remove debris from the air filter, try cleaning the filter. If it is not possible to clean the air filter, replace it. 

McQuay Air conditioner fan not working 
The dual shaft fan motor (or circulation fan motor) might be defective. The circulation fan motor has two fan blades: one on either side of the motor. On one side, the fan blade draws in outside air over the condensing coil to dissipate the heat. On the other side, the fan blade directs the air over the evaporator coil. The dual shaft fan motor has bearings that can loosen or bind over time. To determine if the motor bearings are defective, wiggle the motor shaft. If the motor shaft is loose, or if it won’t turn at all, replace the fan motor. 

McQuay Air conditioner compressor won't run 
The temperature control board provides voltage to the fan motor and compressor. If the control board is defective, it may stop providing voltage to the compressor. Control boards are often misdiagnosed. Before replacing the temperature control board, make sure you check more commonly defective parts—particularly the compressor overload, capacitor and the compressor itself. If you are certain that all of the other components are working properly, replace the temperature control board. 

McQuay Air conditioner won't turn off 
The condenser coils dissipate the heat as the refrigerant passes through the coils. If the condenser coils are dirty, they won’t be able to dissipate the heat as effectively. As debris builds up on the coils, the air conditioner will become less efficient, causing the air conditioner to work harder to cool down. If the coils are significantly dirty, the air conditioner will not be able to maintain the proper temperature, and the compressor will run continuously in an attempt to cool the room. Check the condenser coils to determine if they are dirty. If the condenser coils are dirty, clean them. 

McQuay Air conditioner is loud or noisy 
When the compressor is wearing out, it generates more noise than usual. When this happens, it is not necessary to replace the compressor—compressors often last for years after they become noisy. However, if you would prefer to have a new compressor, have a licensed professional replace it. 

McQuay Air conditioner remote control not working 
First, try replacing the batteries in the remote control. If installing fresh batteries doesn’t solve the problem and you can still operate the air conditioner manually, the remote control might be defective. If you think the remote control is defective, replace it.
