Shop vac doesn't work. Does my shop vac have a thermo fuse?

possible a start/run capacitor failure
take it to a vac shop for diagnosis and repair

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.

Thermo fuse in the field winding, opens when motor overheats.

That Model of Shop vac often has on/off switch failure.

There is a hidden thermo fuse in the tape on one of the field windings. If it overheats that fuse will blow and the motor won't run until replaced.

Are you sure that the filter is pushed all the way to the bottom of the container? Just take it out and put it back and make sure the filter retainer is gently turned all the way.

There is a thermo fuse in the field winding under the tape. When it overheated the fuse went bad.

I just picked up a similar model someone was throwing away. turns out there is a thermal fuse inside the motor housing that blew. I just need to find the values of the fuse and repalce with appropriate size. motor runs when fuse is bypassed.

I had the same problem with the same model. Turned out to be the thermal fuse on the motor housing, between the switch and the windings. Took it apart and replaced the melted solder with 14 guage copper wire. Works fine! No thermal protection but I don't use it for long at a time anyway. Check the switch for continuity, if good then check the thermal fuse for continuity. If good, it's the motor.

Some models have a fuse that blows but it is not replacable.
