If the thermostat. Check for a frozen fan motor motor won t turn manually when power is off. Tighten the allen screws up securing the motor inside the squirrel cage. If the thermostat does not have continuity replace it.

Put the motor and fan back into the ac unit. If the compressor is running but the fan motor is not running the fan motor or the fan motor capacitor are likely at fault. Some thermostats may also control a heater and as a result will have three terminals. If your air conditioner fan is not spinning the problem could be a faulty belt.

Examine the filter to see. This is one of the most common and easy ways to know if your air conditioner blower motor is broken or not. Most of these air conditioner problems require a professional.

Put the fan onto the new motor shaft keeping the flat spot on the motor shaft in line with the allen set screw on the squirrel cage. If the condenser unit fan won t start at all check for power to the unit and to the fan motor and that all of the controls are calling for cooling or heat pump operation. Buildup on the filters blocks airflow and causes the air conditioner to shut down. Does not have continuity replace it.

Your system s air filter traps dust dirt and other airborne pollutants to keep indoor air and internal cooling system components cleaner.
