American standard air tub motor hums

Trey, motor or pump is seized, have tech. take a look and repair.

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

a Humming motor is an indicator that the motor needs replaced.

there may be something caught in the impeller in the jet motor. remove it and clean it out.

i am assuming this is a jacuzzi make sure the air ports are not clogged it has to **** air to be able to make bubbles

look on the back of the motor there should be a shaft that you can try to turn to spin free because something inside the pump is blocking it. rate me if this is helpful.

is this a new install? if so you may need to adjust the air intake. Or if you have kids they may have messed with the settings. If the air is closed all the way off....no bubbles.

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.
