That motor solution is correct. I called the company American Standard and fortunetly, mine was still under warranty. They sent out a plumber within 3 days to replace the motor and now I'm back in Kansas Dorothy.

Re: american standard air tub motor hums
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.

In my case I took the motor out and used a screw driver to turn the impeller in the front of the pump and the fins inthe back. Put it back together and it worked. I then used 2 tablesoons of dishwashing detergent and 1/2 cup bleach and ran it for 20 minutes to clean and degrease the impellers
The bearings (or bushings) of the pump or pump motor have siezed, these can be replaced on some models but for the most part you will need to replace the pump and/or pump motor. and as where to get parts, i would suggest the outlet from wich you purchased the unit or another appliance outlet. Or if you feel up to the challenge, im sure you could find replacement parts on the internet: google, ebay, etc.
Check the air vacuum switch and line as you may have a air vacuum leak. The button that controls the on and off to the jets is an air vacuum switch....It may have a slow air leak in the line or connections that is activating the on and off control
When a motor hums, it usually is the result of what is called "locked rotor." This can occur when the motor's brushes remain on one pair of the commutator contacts. The magnetic field does not shift to the next set of windings and the rotor is locked in place by the unchanging magnetic field.
If you have access to the motor, turn on the power briefly and place your hand gently on the side of the motor. Probably you will feel the vibration of the hum you are hearing, together with some heat. In locked-rotor condition, the motor draws high amperage and heats up quickly. Turn off the power.
If this is the condition, the motor is shot and needs to be replaced. You should copy down the information from the name plate (model and serial number, manufacturer, horsepower, amperage, etc.) and contact the manufacturer or a local appliance parts store about a replacement.
As you said that you recently bought the house, you may have a home-owners warranty which may cover the appliance.
