Question: Csb121 Need Repair Help

Circular saw looks good, motor doesn't work. worked perfect one day, next day nothing. Switched outlets, no good. Brushes clean. Continuity from plug to brushes. Continuity through switch on white wire. Continuity through black wire when switch is closed. Any ideas why motor doesn't work?

Question: DOES NOT RUN

WILSON

I bought my CSB 121 circular saw about 2 years ago and used it about 2 times when i tried to use it today it would not run .Is there a replacement warranty on this saw?

Question: Blade Won

paul

I got the saw 2 years ago but never used it. I went to use for first time and the motor works but the blade doesn't spin. I took it apart and I see that the small gear that is attached to the motor and it does not touch (mate into) the gear that the blade attaches to.
