motor wont run

[rick]

The motor had a chattering noise when first starting then it stopped running so I changed brushes. It still will not run. There is power through the switch, I have not checked the soft start circuit board. It doesn't make a noise when turned on.

Hi Rick,

The chattering noise could be caused by a damaged commutator. Remove the brushes and slowly rotate the blade while looking at the commutator. Any damaged or missing pads on the commutator could create the noise you heard and cause teh motor to no longer operate.

I hope this helps!
