Take the screwdriver and touch both the fan and the c common tabs on the top of the capacitor to discharge the fan side of the capacitor.
Air handler fan capacitor.
A capacitor is a piece of electrical equipment that stores energy.
Make a note which wire is connected to which terminal ex.
440 volt 80 7 5 mfd round double run capacitor.
If the reading doesn t match the rating replace the capacitor.

It is connected to the condensing unit power supply 220v and collects energy until it is needed.
Brown to fan red to c purple to c yellow to herm each brand of system may vary.
Additionally air conditioners and heat pumps are different in certain ways.
While the heat pump condenser will run in the summer and the winter.
Wiring an air conditioner condenser run capacitor compared to a heat pump condenser run capacitor.
How to test your air conditioner capacitor.
Using a stick you can push the fan while the air conditioner is running.
The air conditioner condenser will usually only run in the summer.
The air conditioner fan is located in the condenser unit the portion outside your home.

The blower motor in your furnace or air handler also uses a capacitor.
It s not storing the energy needed to start the fan motor but has enough to keep the fan running.
Ac fan motor maintenance.
If your fan isn t running a simple test can tell if the capacitor is having troubles.
Item 1205190 model 127080.
The condenser fan motors in both.
When the air conditioner needs to come on the capacitor sends a high voltage jolt upwards of 400 to 600 volts to the compressor fan motor and blower motor.
Typically it is a low mfd rated run capacitor and not a dual capacitor.
If the fan starts moving your capacitor is most likely damaged.
