UPDATE: fixed. see below.
First post, and of course I lead off with an issue.
Hello everyone. I've got a CT22E where the variable speed does not work. I'm fairly certain this is out of warranty (I would guess it was purchased around 2008), and I have no paperwork for it.
That being said, I opened the unit up and did some investigating. The only other thread about this issue, that I was easily able to find, had a post mentioning a broken post form the knob to the rheostat. That is not the case here. I also de-soldered the rheostat and tested it, without issue. It shows roughly 0 ohms (with the accuracy of my meter) at the "max" speed setting, and roughly 261K at the "min" speed setting (the device has 250K stamped on it, so I'm guessing within the spec for this part).
That being said, the vac runs just fine otherwise. However, no speed control obviously hampers my sanding ability.
I just picked up a couple of used sanders (RO 125, DX93E), on Craigslist. I know the variable speed used to work, but I haven't had the sanders and haven't used the lower speed. So I'm not sure what died or changed.
Any thoughts? Any ideas on cost to fix? Nothing is physically noticeable on the main board, but I haven't tested any of that yet. I'll search around for a number to call and ask, but I just wanted to see if there were any ideas out there.
Thanks, I'm excited to get up and running with these sanders.
