CPLC 7060V cut-in

[Darrell]

Similar to another problem that I saw posted on your forum, I have a Porter Cable CPLC7060V TYPE 1 (I believe) and when there is pressure in the tank, when the air pressure hits the cut-in set point. The motor attempts to restart but kicks out the 220 breaker. When I drain the air from the tank down to nothing, and reset everything, the compressor starts up and produces air and reaches the cut-out set point and shuts down properly. But as I use air, when it reaches the cut-in set point, the same thing happens again. I did replace, as you instructed someone else, the check valve (A19175) but nothing changed. Same thing still happens. Do you have any other input as to what could be causing this and an idea on how to go about checking/verifying whatever that suggestion may be? Any input you may have will be helpful!

Darrell, what you have sounds like a bad starter capacitor on the motor. This is under the little box attached to the motor. The starter capacitor gives the motor a surge of power to get it started. If it isn't sold as a part get the numbers off it and check with a motor shop about replacement. Hope this helps.
