Air Conditioner Not Cooling? Air Conditioner TroubleshootingAn air conditioner dual shaft fan motor is the component that spins both the condenser fan blade in the rear of the unit and the fan blade that forces the cooled air out the front vent. If the fan motor is burned out, the unit will not be able to blow enough air. You can use a multimeter to determine if power is reaching the fan motor. If power is reaching the motor, but it doesn't run, the component will need to be replaced.
An air conditioner fan motor is the component that spins the fan blade or blower wheel to circulate the air. If one of the fan motors is burned out, the unit will not be able to blow enough air. You can use a multimeter to determine if power is reaching the fan motor. If power is reaching the motor, but it doesn't run, the component will need to be replaced.
Both the indoor and outdoor coils need to be clear for the air conditioner to work efficently. A clogged or restricted coil will reduce air flow causing the unit to run longer. If the coils are clogged or restricted they will need to be cleaned.
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.
If the air filter becomes clogged with dirt, it restricts air flow over the evaporator coils. If the air flow is reduced, the evaporator coils get too cold, which then causes the humidity in the room to condense on the coils and freeze. As frost accumulates on the coils, the frost restricts the air flow even more. Eventually, the entire evaporator coil assembly will frost over, causing the air flow to be completely restricted. If the air filter is dirty, replace it.
