Many large electrical motors found on shop tools or in the AC and heating systems of your home use a start capacitor to assist the motor on startup. Table saws, jointers, band saws, dust collectors and other tools all typically have start capacitors. Your central air conditioning condenser pump uses a start capacitor. In this video I'll use my dust collector as an example of how to troubleshoot motor starting issues and how to test start capacitors safely using a meter.


In this case my start capacitor tested good, but at the end of the video I'll show what proved to be the real issue why my dust collector motor would sometimes snap a breaker when switched on in colder ambient temperatures. Problem solved!
