I finally found a decent used drill press at a decent price yesterday. Tested it one time yesterday with a 1-3/8” forstner bit and it worked fine. I went into the shop this morning and now its spinning in reverse. It takes at least 3 cycles of Off/On to get it to spin correctly. I have never seen this before. I sent the guy an email and have yet to get a response. Not a happy camper this morning :(

Here’s a video of what it’s doing.

Sorry, the motor is going bad.

Sounds like the start capacitor switch has dust or dirt or gunk on it.

It is meant to close the contacts when the motor stops to let it start again in the right direction.

Clean it and you’ll probably be OK.

Yup dirty inside. You still have a good drill press even if you have to get another motor.

Blew the motor out pretty good. One wire was partially burnt on the capacitor so I soldered it back. Still doing the same thing. I can spin it in the right direction by hand then hit the switch and it runs fine. New capacitor?

Check the start capacitor Switch.

Just opened up the motor. Wire nuts and electrical tape. Looks like it was doctored up to sell.

What model DP, model of motor, etc.
Get the manual for it online.
If it runs at all, in either direction a little wiring and clean up is not that difficult.

sounds like something is not connected properly. do you have the motor wire diagram (usually printed on the motor/motor cover)? I would check to make sure everything is connected according to where it should.

Yeah. I think I need a little more research. Everything seems to check out fine. Excuse my ignorance….by capacitor switch do you mean the main on off switch? I understand household wiring but simply don’t have experience with electric motors. If so the main switch checks out fine.

The main power from the cord goes into the motor and branches to both the start and the run capacitor.
The run capacitor is energized first to give the motor a burst of energy to start.
There is a switch _after that capacitor that opens, (it is centrifugal) and it opens after the motor starts so the energy goes to the run capacitor.

Hmmm, I don’t like this one, hang on a second while I edit.

Use this one:

First off, LumberJocks is awesome. Great community here.

Model # 11-990 (type 1)
Not sure where the capacitor switch is located. Thanks for your patience with me. Here is a short video of what I have so far. Do I need to open up the motor housing?

Yup, I couldn’t find a diagram either, but….
The switch you show is the on/off switch.
The switch you want is inside the motor case.
Follow the Black wires up through the start capacitor and whatever color comes out of the start capacitor.
At the end of one of those wires you’ll find the switch which you seek.
It is “centrifugal” meaning it uses the spin of the motor to open and close.

Other than that, I can’t help much as I don’t get into the motors themselves very much

Jay, it looks like the motor’s name plate has a motor model number try researching that. If it is the start capacitor switch then you would have to remove the end plates on the motor to get to it. It has been a while since I worked on motors, but I think you only have to take one of the covers off, which one is unknown. Be very careful that you get everything back inside the motor correctly. I would pull the motor off the drill press and work on it at the bench.

Other alturnatives include living with it as you know how to make it spin correctly; replace the motor.
