Your carrier air conditioning unit may fail to operate properly if its filter is dirty.

Carrier air conditioner fan motor not working. If the thermostat. If your air conditioner fan is not spinning the problem could be a faulty belt. Some thermostats may also control a heater and as a result will have three terminals. Your system s air filter traps dust dirt and other airborne pollutants to keep indoor air and internal cooling system components cleaner.

Another common and easily remedied situation that sometimes results in a central air conditioner fan not working is a dirty clogged air filter. If the compressor is running but the fan motor is not running the fan motor or the fan motor capacitor are likely at fault. Air filter is blocked. 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 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. Put the motor and fan back into the ac unit. 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 both the compressor and the fan motor won t run use a multimeter to test the temperature control thermostat for continuity. Additional issues with the outdoor condensing unit might include a faulty compressor a failing condenser fan motor or a faulty run capacitor.

As was the case with evaporator coil issues a condensing unit might have an excessively dirty coil or refrigerant leakage. Check for loose disconnected wires. If both the compressor and the fan motor won t run use a multimeter to test the temperature control thermostat for continuity. Most of these air conditioner problems require a professional.

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