Hvac Condenser Fan Motor Troubleshooting

There are usually two bearings on the front of the motor and two bearings on the rear.

Hvac condenser fan motor troubleshooting.

A c or heat pump fan condenser unit diagnosis repair. 1 wire to condenser motor and 2 wires to fan motor. The ac contactor the start run capacitor s and the condenser fan motor. If the condenser fan motor is receiving the correct voltage but the motor still won t run inspect the capacitor to ensure that it is not at fault.

And while that explanation makes sense an air conditioner has so many parts that it can be confusing to figure out which specific component is causing the ac to fail. If you are near the condenser unit and it feels hotter than usual it indicates that the fan motor may be overheating. All motors including alternating current ac fan motors have bearings fitted between the armature and the motor housing. Amana a c unit condenser fan bad changed out and changed the recommended capacitor for it however it went from a 3 port to a 2 port capacitor.

To determine if the condenser motor is working use a multimeter to test the incoming voltage to the motor. Now the start cap is hot and leaking. Keep your cool and check out. The condensing unit also houses the compressor but only a pro can replace that.

The air conditioner fan is located in the condenser unit the portion of the ac that is parked outside your home. In most cases the ideal temperature is around 150 degrees fahrenheit. The condensing unit houses the three parts replaceable by a diyer. 2 yellow wires together on old and a red wire on another port.

The bearings allow the armature to rotate freely without causing friction. Not sure how to wire it up. Especially during the summer the condenser fan is hard at work pulling heat out of the engine cooling system and air conditioning system but if something isn t working right you could be left with abnormal noises engine surging or misfiring overheating engine and transmission or inefficient air conditioning.
