Coleman Air conditioner compressor won't run
If your Coleman air conditioner compressor won’t run, the fan may still operate while the unit never starts cooling because the compressor is not getting power or cannot start safely. The most likely cause is a failed temperature control thermostat, which can have burned electrical contacts that allow the fan motor to run but keep the compressor off. Next, check the temperature control board, since it sends voltage to both the fan motor and compressor and can stop powering the compressor if defective. A bad thermostat can also prevent the compressor from starting when the room temperature rises. The compressor overload is another common failure point, and you can test it for continuity with a multimeter. The compressor itself may be bad, but check the overload protector and capacitor first, since compressor replacement should be handled by a licensed technician. A failed thermistor can also keep the Coleman AC compressor from turning on. Enter your Coleman air conditioner model number on RepairClinic.com to find the exact replacement thermostat, control board, overload, thermistor, or other part that fits your unit.
01 - Coleman Air Conditioner Temperature Control Thermostat
The temperature control thermostat has electrical contacts inside that burn out over time. It is possible for the thermostat to still turn on the fan motor but not the compressor motor.

Highly Likely
02 - Coleman Air Conditioner Temperature Control Board
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.
Highly Likely
03 - Coleman Air Conditioner Thermostat
The thermostat monitors the temperature of the air. When the air temperature rises above a set point, the thermostat activates a switch to provide power to the fan and compressor. If the thermostat is defective, it may prevent the compressor from running. If you determine that the compressor is at fault, replace it.
Highly Likely
04 - Coleman Air Conditioner Overload
The overload protects the compressor from burning out if it draws too much current. Over time, the overload can burn out. To determine if the overload is burned out, use a multimeter to test the overload for continuity. If the overload does not have continuity, replace it.
Highly Likely
05 - Coleman Air Conditioner Compressor
The compressor itself might be defective. However, this is not usually the case. Before replacing the compressor, be sure to check more commonly defective components—particularly the overload protector and the compressor capacitor. If the compressor is defective, it should only be replaced by a licensed technician.
Highly Likely
06 - Coleman Air Conditioner Thermistor
The thermistor is a sensor connected to the control board that detects the temperature of the outside air. If the thermistor does not have continuity, it can prevent the compressor from running. To determine if the thermistor is at fault, use a multimeter to test it for continuity. If the thermistor does not have continuity, replace it.
