Luxaire Air conditioner coils freezing
If your Luxaire air conditioner coils are freezing, the problem usually starts with restricted airflow. A dirty or damaged air filter is the most likely cause because it limits air moving across the evaporator coil, letting moisture freeze and build into a larger ice blockage. If the AC coils are frozen in just one area, a sealed system refrigerant leak may be the issue, which requires a licensed technician. A dirty evaporator coil can also reduce airflow enough to cause evaporator coil freezing, especially if the blower wheel is clogged. If airflow parts are clean, check the dual shaft fan motor or fan motor. These motors spin the fan blade and blower wheel, and if a motor has power but will not run, air will not circulate properly and the coils can freeze while the compressor and condenser overheat. RepairClinic.com can help you match the right Luxaire air filter, fan motor, dual shaft fan motor, blower wheel, or related part.

01 - Dirty or Damaged Air Filter
If the air filter becomes clogged with dirt, it restricts airflow over the evaporator coils. If the airflow 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 airflow even more. Eventually, the entire evaporator coil assembly will frost over, causing the airflow 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.

02 - Sealed System Leak
If the air conditioner coils are freezing in only one area, there may be a sealed system (or refrigerant) leak. This is normally a very expensive repair. Repairs to the sealed system must only be performed by a licensed technician.

03 - Dirty Evaporator Coil
Proper air flow is critical for the air conditioner to work properly. The evaporator needs sufficient air flow to keep the condensing water from freezing. If the evaporator coil, air filter or blower wheel gets clogged, air flow will be reduced and ice can start forming on the evaporator coils, eventually freezing them up. It is recommended to replace the air filter routinely. Refer to owner's manual for air filter replacement frequency recommendations and for evaporator coil cleaning instructions.

04 - Luxaire Air Conditioner Dual Shaft Fan Motor
An air conditioner dual shaft fan motor is the component that spins the fan blade and blower wheel to both draw air into the unit and force it through the front vent and out the rear condenser coil. If the fan motor is burned out, the air won't be circulated which can cause the coils to freeze and the condenser and compressor to overheat. 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.

05 - Luxaire 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.
Common
06 - Luxaire Air Conditioner Fan Motor
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 air won't be circulated properly which can cause the coils to freeze. 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.
