Air Switch Repair It sounds like you have a bad air switch located in your motor. The air switch is what the air hose connects to on the back of the motor or on the box on top of the motor. The other end of the air hose is connected to the air button on the lip of the tub. This is a latching air switch and when you push the air button it latches and sends the power to the motor.
