Bryant Air conditioner not cooling

If your Bryant air conditioner is not cooling, start with the simple airflow checks before assuming the sealed system has failed. A clogged air filter is the most common cause because it restricts airflow, cuts cooling capacity, and can make the evaporator coil frost over. If the filter is clean, the next likely issue is the user control and display board, which may keep the unit from setting or reading the correct cooling temperature. Dirty condenser coils can also cause an AC not cooling problem by trapping heat and making the compressor run continuously without lowering the room temperature. If the Bryant air conditioner is blowing warm air or not getting cold, a failed dual run capacitor may prevent the compressor or fan motor from running. The compressor itself can fail, but check the overload protector and capacitor first, since compressor replacement usually requires a licensed technician. A bad thermistor can also misread air temperature and interfere with cooling. Enter your model number on RepairClinic.com to find the exact Bryant replacement part that fits your air conditioner.

01 - Bryant 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.

02 - Bryant Air Conditioner User Control and Display Board

The user control and display board allows the user to operate the unit by selecting fan speeds and cooling temperatures. If the board is defective, it may not allow the unit to be set to a proper cooling temperature. If the temperature sensor or thermistor tests appropriately with a multimeter, it's possible the user control and display board is malfunctioning and will need to be replaced.

03 - Condenser Coils are Dirty

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. Refer to owner's manual for cleaning instructions.

04 - Bryant Air Conditioner Dual Run Capacitor

A dual run capacitor will power both the compressor and the fan motor. If the capacitor burns out, the compressor or fan motor will not run. To determine whether the capacitor is burned out, use a multimeter to test it for continuity. If the capacitor does not have continuity, replace it.
Highly Likely

05 - Bryant Air Conditioner Compressor

The compressor 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 - Bryant Air Conditioner Thermistor

The thermistor is a sensor connected to the control board that detects the temperature of the air. The resistance value of the thermistor changes in conjunction with the air temperature. If the air temperature rises, the resistance value will decrease. To determine if the thermistor is at fault, use a multimeter to test it for continuity. If the thermistor does not have continuity, or if the resistance of the thermistor does not change with a change in temperature, replace the thermistor. (To find specific temperature and resistance values, try checking your user’s manual.)
