How to Check a Start Capacitor

2009-8-17

   1. Remove the start capacitor and use a screwdriver to shorten the two terminals and discharge the electricity from it.
   2. Set your analog meter on 1k ohms.
   3. Touch the two terminals with your ohms meter test leads.
   4. Reverse the way that you were touching the two terminals with your ohms meter test leads.

          * The needle in your meter should swing to 0 ohms and swing back to infinity every time that you reverse the ohms meter test lead on the start capacitor.
          * If it does that, the start capacitor is good.
   5. Set the meter. On a digital meter, set it to at least 1k ohms.
   6. Touch the two terminals with your ohms meter test leads.
   7. Reverse the way that you were touching the two terminals with your ohms meter test leads.
   8. Notice that the meter will display some numbers for a second.


          * Then it will return to OL (open line). It should do this every time that you switch the ohms meter test leads position.
          * If it does this, the start capacitor is good.
