I hope someone can help me. I was given a Sears Radial Arm Saw that
does not work. The model number is 113.197750. When I turn it on, the
motor hums but does not turn. I turn the motor when it is on and it
turns freely but will not spin on its own.
I have done some searching on Google and tried some of their solutions
without success. I took the motor apart and cleaned out all the
sawdust. In addition, I banged on the arbor as someone mentioned but
it did not fix anything. All the copper wiring on the motor that I can
see looks new. There are no dark or burned spots on the copper.
I tried a multimeter on the incoming power and it is getting 120 volts.
The strange thing is that the leads to the capacitor do not register
any power when the motor is on. I checked it a few times and the best
it showed was 1 volt but it quickly went to zero. On one try when I
left the motor on for a few seconds, the motor turned 1/4 revolution
then stopped. I could not get it to turn anymore on its own. Does
that mean it needs a new capacitor? I am not very knowledgable with a
multimeter but think I checked it correctly.
I would love to get the saw working as it is in great condition and I
learned that a free repair kit is available since the saw has been
recalled. Any help anyone can offer would be appreciated.
