I have taken out the motor and it does not turn freely , how do you strip down the j-end

It is not ideal having a power strip due to the amps it draws, but the fact it hums, leads my to believe that the start/run capacitor on the motor might be failing.

no! You have to remove the pump end to find the shift, You may look between the pump and motor and find the shift splice and set screws that need to be tighted up.

Turn off the power and remove the end cap at the center back end of the motor. The end of the motor shaft is then exposed and you can use a 9/16" open end wrench to verify that the motor shaft is turning freely.
If it offers resistance the pump needs to be opened and checked to find out why. If it does move freely, take it to a pool store or motor shop to test it. Rarely, a motor gets out of the factory DOA.

Does it make any noise at all? If not, check the motor for a protective device. A thermal reset would be a red button on the end of the motor. It may be as simple as that.

If it hums loudly, and turns over by hand- no power applied- with difficulty the motor bearings or compressor bearings may be needing attention.

If it hums loudly and barely turns, but turns by hand freely, the motor has a start/run capacitor- it likely failed. Replacing the capacitor is a simple task- just make sure to replace it with one of similar ratings.

You got to strip the machine down. Switch off, bring saw blade down to below table level, turn over machine remove 4 Phillips screws undo and remove guard remove motor, strip down motor replace parts and generally wipe clean, ensure brushes allow armature to turn freely. Refit in reverse order. bingo.

Turn off the power at the breaker, then reach in to the impeller and see if it will turn freely. If it does you probably only need to replace the capacitor. If it will not turn freely you'll have to remove the motor end by unscrewing the large ring that holds the motor to the wet end. Remove the small screws that hold the diffuser cover and inspect the impeller and impeller ring, sometimes known as an impeller weir or floating eye seal.
Even if you have to replace the motor this pump is worth saving if there is no damage to other components. Note: Replacement motors are easy to find, I favor Magnatek / A. O. Smith motors but any brand such as Emerson or other will do. Jacuzzi parts though are getting increasingly hard to come about.

I had the same problem, it was just humming, then after a few second the on board circuit breaker would cut out. After a little while I could hit the reset button and it would just hum again.

It turns out that the base of the disposal was jammed. There are 2 blades on the top that should spin freely, but the base plate that the blades are attached to also spins. In fact, that's what the motor drives. The two blades on top are not powered, they just flip back and forth as the base spins. So get a broom handle or a strong wooden spoon, stick it down in there, and try to pry the base plate free so it spins. That should do it.

yes the pipe is the same size all the way through, if it is just humming and there is nothing blocking it, the motor could be going bad and doesn't have the power to turn the pump,, did you check to see if the shaft could be bent> like as if a rock may have gotten stuck but broke loose before you took it apart

Could be something jamming the fan blade but if the motor shaft turns freely then your motor is bad.

Your motor is probably stuck.
Remove power from the D/W.
Remove the lower access panel. The motor will be in front of you.
Turn the blades in the end of the motor counterclockwise until the motor turns freely. You will need a flat screwdriver to reach in and turn the blades.
When it frees, repower and try it again.
