How to Check a Start Capacitor

If the motor on your washer makes a humming noise, but it won't start, check the start capacitor. If the start capacitor is open, the motor will not start.

Steps

1

Remove the start capacitor and use a screwdriver to shorten the two terminals and discharge the electricity from it.(Touching the screwdriver across the two terminals shorts/discharges the capacitors stored energy). See picture.

Analog Meter

1. 1
   
   Set your analog meter on 1k ohms.
2. 2
   
   Touch the two terminals with your ohms meter test leads. See picture.
3. 3
   
   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. See picture.
   • 
     If it does that, the start capacitor is good.
