porter cable cplc7060

[mbradshaw]

Hi,I have a porter cable mod.cplc7060v-1.The problem is the motor won't start if there is any air in the tank,it tries but then it kicks the reset.I think it might be one or both of the capcitors on the motor.Is this where I should start.
thanks

Hey mbradshaw,
Most likely it is the check valve...part # A19715 that is the problem..[it lets air in to the tank and not back out]..so what is happening when the motor tries to restart.. there is back up pressure in the head of the pump from the air leaking back out of the tank it and creates too much of a load on the motor.. an easy check is to loosen the nut on the small bleeder tube after the air comp has filled up and shut off..if it leaks any air..its the check valve..however, the motor might have some issues also from the hard starts..and you may also have a stuck head valve causing another load or heat problem..

hope this helps..
