My chipper hums when i turn it on but the blades dont spin. I took it apart and cleaned it, the blade is freely spinning by hand. put it back together and it still just hums. what next?

With the mower turned OFF check the blades to see if they aren't bent and if it spins freely. There should be resistance when you hand turn the blades. A bent blade can jam and lock up the drive system. If the blade spins freely and has no resistance check the drive belts from the blade pulley to the gears that run the blades. Hopefully you have just had a drive belt come loose or break, a reasonably cheap and easy fix. If the belts are OK you will need a mower mechanic to look at the gearing for the blades.

if you can spin blade freely by hand change capacitor.

I think that you may have put the blade on backwards. try taking the fan apart and reversing the blade around and reassembling the fan.

I have one of these and LOVE it. Usually what you describe is caused by debris keeping the rotor from turning. Check it again (take off the top part) and be sure the thing spins freely. They're very reliable, in my experience, but you can't let the blade get jammed.

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.

This will take some work, and some elbow grease, but what happened is the motor bushings most likely seized. Try turning the blades with your hand. If they are stiff, the bushings are seized. What you will have to do is take the fan apart. First by removing the blades, then by taking the motor off of the frame. Then depending on the type of bolts/ screws that hold the motor together, remove them. Then split the motor apart by taking a flat blade screwdriver and sliping it between the two pieces of the motor and turning it so they slip apart. then once the motor is apart, shine up and clean the motor's shaft so it is clcan and shiny. then do the same for the bushing/ beringholes in the motor's casing. then drip some oil in the berings, and on the motor shaft, and put the motor back together. then put it back on the frame, and plug the fan in. turn it on. the shaft should just spin without any help. if this does spin, put the blades back on, and put the guard back on. Then you sucessfully rebuilt the motor and the fan!

If the blade and impeller spin freely by hand after removing the obstruction but does not pump out the waste after assembling the unit back together, then could be a bad capacitor, since the capacitor spins the blade and impeller. If the capacitor goes bad then it will just make a humming noise and not pump the waste out.

Wd-40 is not a very good lubricant. It only lasts fror a few days and then dries up again. In order to get your fan working again, take some 3-in one oil and put a drop at the bearing side of each bearing top and bottom with the shaft upright. Spuin and tap the motor briskly with a small tack hammer or screw driver handle. This will impact and allow the oil to get into the bearings Keep tapping and turning until you feel it lighten up a spin freely. Turn it over and do the same thing again. I garuntee that all will be fine after this.

The pump impeller should spin freely and cannot have any broken or missing blades. If the impeller has any broken/missing blades or if it won't spin freely, the pump is defective. Hope this helped and best wishes.

Throw away the fan and buy a new one.
