Shop vac wiring diagram motor - Shop Vac 201-13 Wet/Dry Vacuum

If the motor housing is all plastic and there is no metal the user could contact and potentially receive an electric shock from should a fault occur, the ground conductor if fitted, would be connected to the frame of the motor.

Take it to your local vac shop for repair. Switches are not that expensive.

Motors have a thermal safety fuse in the field winding. If it overheats, it will blow and either can be replaced or the whole field winding will have to be replaced. It is wired and is not considered to be a user servicable item.

what is the problem ?
God bless you
if if suction, test the hose blockage 2) belt drive is worn 3) power brush dirty, clean or replace, 4) test the motor for repair, clean, and lube.

see the diagram

I would go through the manufacturer for the diagram.

Yes replacing the link would work, but that would not fix the cause. You have either pulled the wiring to the point of pulling apart the connection or there is a short. Which would be in the way of a grounding effect causing the link to heat and melt. A safty issue to be sure. Check all contact with housing and motor to make sure there is not an underlying problem to start with. Unpluged of course

I just went through the same problem with a Shop Vac. The switch is easy to replace but not easy to find. After removing the switch, I found a match made by Sigma Switches. They directed me to contact a local RV dealer and look in either their Coast Supply or Stag/Parkway Supply catalogs for the appropriate switch (an H2-28 in my case for a QPL45 Shop Vac). After ordering the switch and $5 later, it snaps in like the original with no problems. Certainly beats $70 for a whole new motor assembly.

well if you can find the motor ( find a place that deals with the manufacturer directly so you get the right part ) and it isnt to expensive, most shop vacs are pretty easy, if you look under the top you should see about four screws, remove those and the top should come of giving you access to the motor, take note about the wires and what they hook up to. i doubt the motor is fastend down other than that.

IT SOUND LIKE THE MOTOR WENT BAD OR IN SIDE THE PANLE A WIRE CAME LOSE

If you remove the motor, you will see that the wires that go from the switch to the brushes. On one side there is one wire connected directly to the brush. On the other side the wire goes to a plastic plug with a second wire going to the brush. This is probably where the problem is. This is a fusible link and it has most likely melted creating an open in the circuit. I put a piece of solder where the link was and the motor ran BUT the brushed arced like a sparkler. Upon further examination the brushes were crumbling apart. I have been unable to find replacement brushes.
This machine has a five year warranty. I called Shop Vac Customer Service 1-888-822-4644 and they sent me a new motor.
I had a Shop Vac QL50EIC which had exactly the same problem but the warranty was expired so that I had to buy another motor for about $50.
