So I just got done replacing the dinosaur era blade on my old 1 HP compact table saw (Black and Decker, 8 inch) with a new freud. Pulled it to give it a test, and it wouldn’t come on. It had the issue of not coming on a couple times a while back, but hitting the little reset button seemed to cure it. Any ideas on what might be wrong with it? There is quite a bit of dust and dirt around the motor, and I did have it upside down for a while replacing the blade. Thanks!

Sawdust may have gotten inside the switch. I dealt with that problem once. Took the switch apart, cleaned out the dust, reassembled the switch. Try vacuuming (with the brush attachment) the entire inside of the machine, especially the motor.

Try turning the blade a quarter turn and trying again.. I’ve had direct drive machines that occasionally stop in just the right spot to keep them from spinning up.. rare, but it happens. If not, grab your meter and trace the voltages to see where the juice stops.. as mentioned above, could be something as simple as a stuck/clogged switch from dislodging sawdust when you turned it over. Also, I’m curious as to why you felt the need to turn the machine over to change the blade.. can’t you access it from the top?

Cheers,

Some of the small direct drive saws have a switch in them that detects whether the table is level. Maybe this got hung up or something from turning it over. Open the cover over the switch and clean it wall. Maybe the inside of the switch too. The contacts may have something in them. Same for the circuit breaker. Those can sometimes by opened and cleaned.

I turned it over simply because it was easier to switch out rather than taking a million screws out. I’ll try to clean it out like you guys said. I took the switch handle off and looked inside but didn’t see anything awry. I’ll post a couple pics here in a minute.

I really hope the motor isn’t fried, but I see no reason why it would be.

I took everything apart and cleaned it. Still nothing. Should I check everything with voltage meter while it is plugged in? Turned on?

Chances are that you dislodged some saw dust that is blocking the contacts on the motor or the switch. The contacts on the motor can be cleaned out with compressed air more than likely you will not have to take the motor apart.Even a well sealed motor has openings that allow dust to get in . Good luck.

Did you check the outlet for power to reduce the possible location of the problem?
Sometimes that is easy to forget to do.

If you have power to the outlet check continuity from the plug end to the switch on all wires. If you have continuity there and if you know how to do it safely, plug it in and check the power on the saw side of the switch. Make sure there is nothing near the blade if you still have it installed. If you have power there I will leave the rest up to the gang here to tell you how to trouble shoot the motor.

Well this certainly isn’t a well sealed motor as you can see from the pictures. I will try blowing it out with air, and if that don’t work, I might just look for a new saw. I went on ereplacementparts.com and all but a couple parts for this thing are unavailable/obsolete. I hate to give up on it but I don’t really know if it can handle the stuff I’m wanting to eventually do anyway.

Check the switch.

I pulled the switch out of the main case and visually it looks fine and flips back and forth. Should I put the points of the voltage meter on the wires going into the switch housing and check it?
