Apparently the motor itself is reversed. It I'd blowing out the top hole.

I cannot find any " reverse" switch cm and I doubt it has one. It apparently got switched into reverse somehow and I need to reset it.

It is a Craftsman 9 gallon (red) .

Any advice?

  • how old is it? Maybe the hose goes on the other hole on the side??? Mar 22, 2014 at 21:07

I'm just tunnel-visioned. I was sure I had plugged it into the correct socket, but no.

Stupid User Trick



Make sure the ball is not stuck inside the housing. It SCHOULD be lose when machine is off completely. always try a different outlet to eliminate that. Then inspect the cord a new plug possibly installed backwards or a cut and repair or even a slice out of the cord. Could cause a motor reversal.

  • the cord on AC would not reverse the motor. Mar 22, 2014 at 21:06

    Only thing that changes the rotation on a universal motor is the commutator brush position. Often not changeable and must be disassembled if it is.. Mar 22, 2014 at 22:16
  • It's a good excuse to check those things.
