Toilets, Sinks, Showers, Tubs and Disposals - Jetted tub motor hummmmms

Just pushed the button on our jetted tub and all it did was hummmmmm. I don't have an access panel to the tub....will have to cut out some dry wall it appears. Sound like the motor is burned out or maybe something else to look for?

Chances are the motor is bad. It's a long shot but reset the breaker. You might get lucky.

Reset the breaker and still humming so looks like I will replace it. Any tricks to replacing this pump motor? Anything I am at risk to screw up? Any helpful direction is much appreciated.

The hardest part is reaching it. Take your time, don't rush & make sure the electrical & plumbing connections are secured. Test it for awhile before you patch the wall.

Got access to motor through closet. Decided to play around with motor before removing and replacing. There was a screwdriver slot on the end of the motor shaft so I decided to use an offset screwdriver to try to see if shaft was frozen. It turned, but with difficulty. I worked it back and forth for a few minutes and then it began to free up. After about 5 minutes of this I could turn the whole thing freely. So I hit the button on the tub and EUREKA, IT RAN perfectly. I filled the tub and did it again and it worked great. I let it run for 20 minutes and did the same thing 3 days in a row. I am closing and the wall (building access panel this time) and calling this a win!. Anything else I should do to the motor before moving on?

Look closely with a flashlight for a small hole that might be used for lubrication.

Thanks. I will do that tonight before I close the wall. Any specific type of lubricant?

If it takes anything, it would probably be a few drops of light weight oil. Do you know who makes the motor?

It is a GE motor. Didn't know if a little 3-in1 would do the trick or something might be needed.

The holes pulpo mentioned will normally be at the front and back right above the shaft, sometimes covered with caps or soft metal plugs.

I kinda doubt you are going to find any..though if its real old maybe it will have some. More likely it had sealed bearings that just dried out over time.

I opened the back wall of a closet once to reach the pipes on a tub. Instead of closeing the wall with sheet rock, I bought a piece of sheet metal about 2' x 2' & used zip screws to secure it, giving me easy access.

That's a good idea. I was gonna just cut simple frame out of some left over trim and put the drywall I cut out in the frame, but haven't figured out best way to keep this in place so I hada hole in my wall while I was "waiting for inspiration."

As you know, inspiration & I guess some perspiration can always be found here.
