I have an american standard air tub and cannot get the air jets to shut off.  They turn off, but come back on automatically a short time later.  How do I shut the power off?

Not normal for that to happen but the jet faces on the two back jets may be turned off or down.
Try turning the face of the jet clockwise and see if you get more water flow out of each jet.

This sounds like the air switch in the motor is not working properly. You will need to remove the pump from under the tub to access the air switch located in a housing on the motor.

Replacement Air Switch will cost you about $20

The problem you are experiencing is common to many jetted bathtubs.It is a result of dried bathing water in the tub. There are a couple of solutions to resolve this ongoing problem.

1. Use your tub more frequently as the water will not have time to fester in the pipes.
2. Use a cleaning solution made for cleaning the pipes on jetted bathtubs once every three months.

check to make sure the jet faces are turned on. some model tubs have adjustable jets that you can turn the face of the jet off.

sounds like maybe the jet faces are turned off. see if they turn one way or the other and they may open and spew water out for you.

The water in the tub needs to be higher than the jets!

Check to see if there are any screen type filter to the tub as debris may be clogging it. Also air lock can occur but it should not be causing problems as 90% clear them selves.....

sounds like the circuit board in your system is faulty

Most of these jets turn to close. Check if you turn the nozzle. Hope it helps

sounds like the motor might be on a dead spot. try turning the shaft of the motor 1/2 turn or so and see if it will kick in. If not you may have a bad motor of some debris in the motor preventing it from starting.
