Trim Router Hums but doesn’t spin.
A couple of years ago, one of my Porter Cable 7310 trim routers had the on switch fail in the on position, (it was a little disconcerting, but the flat top let me put it down safely until I could pull the plug).
I finally decided it was time to fix it a few weeks back, and ordered a new switch, and brushes.
I installed the new switch, both brushes, and a new cord. The bearings, seem fine, and I lubed them while I had it apart.
Got it back together, and tried it out.
It makes a quarter of a turn, and then just hums. It seems to be just as easy to turn as the other two I own. So, I don’t think it is bound up.
Anybody have any ideas of whats not right?
