If your Frigidaire air conditioner is not blowing enough air, or the window air conditioner airflow is weak, start with the parts that actually move air through the unit. The most likely problem is a condenser fan motor that is receiving voltage but not running, often due to a failed motor or a bad capacitor. Next, check the dual shaft fan motor, which turns both the rear condenser fan blade and the front fan blade that pushes cooled air into the room. A failed fan motor can also leave you with AC weak airflow even though the unit powers on. If the motors are working, clogged condenser coils or evaporator coils can restrict airflow and make the air conditioner run longer than normal. A dirty air filter is another common cause because it blocks air through the evaporator coil and can lead to frost buildup that reduces airflow even more.

01 - Frigidaire Air Conditioner Condenser Fan Motor
To determine if the condenser fan motor is working, use a multimeter to test the incoming voltage to the motor. If the condenser fan motor is receiving the correct voltage, but the motor still won’t run, you should inspect the capacitor, if applicable, for any bulging or leaking. You can also use a multimeter to determine if the capacitor can hold and release its charge. If the capacitor appears to be in good condition, replace the condenser fan motor.

02 - Frigidaire Air Conditioner Dual Shaft Fan Motor
An 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 efficiently. A clogged or restricted coil will reduce air flow causing the unit to run longer.

05 - Frigidaire Air Conditioner Air Filter
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. Most air filters used in stand-alone air conditioners can be cleaned with soap and water. Only filters that are extremely clogged with debris or damaged will need to be replaced.
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. Most air filters used in stand-alone air conditioners can be cleaned with soap and water. Only filters that are extremely clogged with debris or damaged will need to be replaced.
