Hi Inyopools,

I want to know what is the function of the capacitor positioning over the motor body pump?because inside the motor is already installed capacitor also.

And what is the difference with the photo pump i had before?

Thanks.

Hello Philip - You original motor was considered a capacitor start motor. This is a very common standard efficiency motor. It uses the start capacitor, in the back, to provide extra torque when the motor turns on. The start capacitor is taken out of circuit once the motor reaches 2/3 to 3/4 of full speed.

The new motor is a capacitor start/capacitor run motor. This is an increased efficiency version that has a run capacitor on top and a start capacitor in the back. The run capacitor remains in circuit at all times.
