I have a circular saw that quit working for no obvious reason.
I cut a board and sat the saw down to get another board.
When I tried to cut the next board, the saw wouldn't work. Pull the trigger and nothing happens.
Is a circular saw DIY repairable? If so, where would I start looking?
EDIT
Sorry, here is what I've tried.
- Verified outlet has power.
- Removed blade and blew out all debris (doesn't work with blade out either).
- Jiggled the cable. 🙂

If the switch feels funny and/or nothing happens when it is turned on, then it could well be a busted switch -- which is pretty common. You can sometimes get replacement switches at a reasonable price.
If the motor arcs excessively (a little visible arcing is normal), the brushes may need replacing. Do not run the tool if you suspect brushes, you can permanently damage the motor.
If the motor hums or smokes, it's typically one of these problems:
