It would be a good idea since the points inside the switch are welded together and produce heat.

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

Amazon is your best bet. Type in 120 volt rocker switch

From what I have heard, the switch on these units can sometimes be defective. Also, looking closely at the the AC cord may help determine if there is damage to it that should be repaired.

Yes, you need to remove head unit from canister and pull head unit apart, switches are usually common and are just push in. available from electronics suppliers

I got a replacement switch at a local electronic supply store: Philmore Miniature Rocker Switch part number 30-043. Shop vac changed the switch recently to two push buttons from the old rocker style. This update works a lot better.

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.

If by stopped working you mean that it no longer has any suction, then check the hose for a clog and also clean all the filters.

If you mean that it literally stopped running, then the most common cause is a faulty switch. If the machine is still under warranty, contact Shop Vac for a replacement motor, Switches for shop vacs are not available, only replacement motors. If the machine is not under warranty you can either replace the motor or the whole machine.
