Milwaukee Magnetic Drill 4203 Low voltage light flashing. It will flash plugged directly into the wall socket. New control board 5 years ago. Barely used. I drilled 4 holes last week & low voltage light can on after last hole & hasn't worked since.

Re: Low voltage light flashing
I haven't worked on one of them in years but I looked at a breakdown and the parts are as I remember. Go to Milwaukeetool.com and under parts/service type in your model number and view the wiring diagram for an operational check procedure. I would first look at the cord and is the base sitting on 1/2 or greater plate steel. If rusted or painted you will loose some of the holding force. Also I don't know what motor you have but some of the larger units require a lot of amps to operate and it is possible that even though you plugged it in direct to wall the circuit wasn't sufficient to operate both units. Last resort call the tech dept. at Milwaukee and see if they have any ideas. That panel is a component part as you know and there were no replacement parts for it. Hope this helps if not let me know and I will do some more checking

This is a light weight cordless screw driver, so it all depends on what material you are trying to drill. It will probably drill small holes in wood and possibly in softer metals. It is made for light duty work, so again, it depends on what the material is, so if you are reffering to wall board such plaster board or sheet rock, it will drill smaller diameter holes.
Magnetic drills have a safety system built into them so the motor will not run unless the magnet is on and the tool is sitting on between at least 1/8-inch and 1/4-inch steel. If your drill is sitting on enough steel you may have a problem with the sensor system inside the drill. Those problems are usually electronic parts related and, most of the time, they are R&R (Remove & Replace) method is used until you fix the problem.
they don't sell just the switch, you would need to replace the control panel. You can go to milwaukeetool.com and find a service center/parts supplier on their site. If you have trouble finding one give me your general area with zip code and I will see what I can do to help.
I am assuming that you have this tool on some steel. If so and the unit will not turn on I would think that the panel is bad. You can find the breakdown and wiring instructions for this tool by going to milwaukeetool.com and typing in your separate model number but you will need the serial number also.
go to"milwaukeetool.com and type in your model number, you will also need the serial number to locate the information you requested. You might need to separate the tools and use the base and motor separately but it is there.
the magnet is actually dc behind the control panel should be a rectifier possibly soldered to a circuit board it will look like a small black square with four prongs if not that mabe a fuse or an open in the circuit.
If I'm not mistaken, these drills use an electromagnet. Start by measuring the current when the magnet is switched on, but not the drill. If you don't have a current meter, just plug the drill plus an incandescent light into a long lightweight extension cord. You should see the light dim a little when you switch on the magnet. If the light doesn't dim, you just aren't getting power to the electromagnet, and it's probably a broken wire or a bad switch. If the tool has it's own fuse, I would think it would be for the drill only, not the electromagnet.
could be a couple things, what thickness material are you trying to drill?? Also if the for/rev buttons are jammed this could cause this, check for low voltage, usually when the buzzer does sound the magnet is not energized and it could be a faulty panel that would need replaced. this tool has a limited 5 year warranty. Let me know what you find and I will try and help more
hi first try the magnet on a clean flat piece of m/s sheet/plate 2 inches bigger than the magnetic base ,it should be very hard to remove make shure the magnetic base is clean and the beam you are drilling is paint and rust free if possible clean up the beam with a sanding disc try it make shure the cutter is sharp and use coolant a dull /blunt tool will need more force a good tool almost cuts with no effort on the handle if you are drilling upside down or on the side of the beam NOmagi drill will do this without extra support silk090
