Why is my air conditioner fan not spinning?
It takes much more energy to get the outdoor fan going than it does to keep it running. It needs that extra boost from a start capacitor. So, if the capacitor attached to your fan motor is bad, the fan won’t start spinning. Here’s an easy way to test if the fan’s capacitor is bad.
Why is my condenser fan motor getting hot?
The most common problem associated with the condenser fan motor getting hot and then stopping is likely the fan capacitor. For a condenser the capacitor is typically a dual capacitor. The dual capacitor is a run capacitor that serves both the compressor and the condenser fan motor.
What to do if your condenser unit fan stops running?
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); check for loose, disconnected wires; Check for a frozen fan motor (motor won’t turn manually when power is off).
What should I do if my fan won’t start?
Capacitor: Check for a bad start/run capacitor if the fan circuit uses one. If the motor hums and does not start techs often try swapping in a new start capacitor. If spinning the fan manually will get it running, the problem is usually a bad starter capacitor.
What does it mean when your AC Fan is not spinning?
If you hear buzzing coming from your AC but the fan isn’t spinning, this can indicate a bad capacitor. The capacitor is a small object that is cylindrical in shape. It stores a large amount of energy. In this way, it’s a bit like a battery.
Why does my condenser fan not start when power is off?
A condenser fan that won’t start when power is turned on, but whose blades will spin easily when power is off may have a worn fan motor shaft bearing. You may detect this by noticing that you can wobble the fan motor shaft (when power is OFF) or you may notice that you can pull the shaft in and out of the motor (loose end-play).
What to do when your condenser unit stops running?
at COMPRESSORE FAILURE DIAGNOSIS. 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); check for loose, disconnected wires; Check for a frozen fan motor (motor won’t turn manually when power is off).
What should I do if my AC Fan is not turning?
Use a stick to turn the fan in the direction of the downward-slant of the blades. If the AC starts working after you assist the fan in turning, that means you may have a capacitor issue. Regardless of the route you take, let’s say your capacitor is shot.
