I've got a DeWalt DW623 sander that's stopped working and I'm trying to pin down the problem. I took it apart and sprayed it out and when I have the top cover unscrewed and I plug it in, it turns on fine. Screw the top housing down and it no longer turns on. It's always been a little twitchy, you'd push the switch and it would take a few seconds for it to come on, or you'd have to toggle it back and forth a couple times.
I looked at the wiring and nothing seems to be loose but that's as far as I've gone so far, I haven't actually tested the wiring. Does DeWalt have a place to order replacement parts or should I just hit Radio Shack for a replacement switch?
Any ideas welcome, thanks.
