Serious Question....Kenmore Vacuum

[fantomfan57]

Note: posted here in case some knowledgeable folks do not look at the Contemporary Posts, but know the answer.

I recently came across a Kenmore Progressive Canister vacuum that the motor would not come on. I had one before this that the motor made terrible noises and then stopped working. That one I gutted and dumped the motor. At the time I noticed the circuit board.

This new one, I decided to try my hand at bypassing the circuit board. After one connection that the motor ran but the PN would not, I switched wires and got the motor to run and switch from motor only to motor and PN.

Is there any DANGER to using this vacuum without the circuit board? If not, why are the boards part of the unit?

I don't think it will hurt anything. I don't know why they put those damn things in there. They all burn out. I'd say if it works use it. I honesty don't know 100% for sure.

Am wondering because....

I don't want to find out later it can cause a fire.

I think someone got it....

protection from an overheating motor. I am thinking about an inline fuse. Say, an automotive fuse case & fuse. Or recycle a part from a Power Nozzle.

I owned both an Intuituin & Progressive
here are some schematics from them

Okay....

after speaking to a friend of mine, who knows, I got confirmation about the fuse and why it will work. He is very good at explaining things (in a way I can understand). Teaches theory, as in why, instead of just telling me what to do.

When I got home, I sliced open the shrink casing on the inline fuse I clipped from the vacuum and found it had blown. I will never know if the "board" had anything to do with the failure.

So I will be off to my local Auto supply to find an inline fuse holder and a 15amp fuse. The blown fuse was a 15amp, the vacuum motor is rated 12amps.
