Carrier air conditioner fan motor not working.

This is one of the most common and easy ways to know if your air conditioner blower motor is broken or not. If both the compressor and the fan motor won t run use a multimeter to test the temperature control thermostat for continuity. Tighten the allen screws up securing the motor inside the squirrel cage. Your carrier air conditioning unit may fail to operate properly if its filter is dirty.

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. As was the case with evaporator coil issues a condensing unit might have an excessively dirty coil or refrigerant leakage. If both the compressor and the fan motor won t run use a multimeter to test the temperature control thermostat for continuity. If the compressor is running but the fan motor is not running the fan motor or the fan motor capacitor are likely at fault.

Most of these air conditioner problems require a professional. Examine the filter to see. 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. Replace and tighten the screws holding the fan motor in place.

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.

Buildup on the filters blocks airflow and causes the air conditioner to shut down.
