Changing out the Air Switch
Air Switch Repair
If your pump is NOT turning on/off.
The air switch is what the air hose connects to on the back of the motor or in the box on top of the motor.
One end of the air hose is connected to the air button on the lip of the tub and the other end connects to the air switch.
This is a latching air switch and when you push the air button it latches and sends the power to the motor.
When the air button is pushed again it opens the latch in the air switch and stops power going to the motor shutting it off.
