porter cable pancake style comp. I have power all the way to the on/off switch, but it wont come on. what could it be?
____________________
Carl, if the power supply hasn’t changed, and you have power to the switch, dump all the air from the tank, and then check to see if power is flowing from the switch to the motor. Is it?
With the tank empty, when you power up the compressor, any sound made… anything happen?
C2005 WILL NOT BUILD PRESSURE
I HAVE A C2005 TYPE 2 PORTER CABLE COMPRESSOR. TURN IT ON , IT WILL GO TO 20PSI AND THATS ALL AND IT KEEPS RUNNING, WHAT COULD BE THE PROBLEM. THANKS EMERY

Hi Emery. There are a number of things that could be the problem. You can see a page linked from the TROUBLESHOOTING page… “compressor will not build pressure”.
In order of frequency, it’s likely that you’ve got a valve (intake or high pressure) failing, a gasket that lets go at 20 PSI and allows air to circulate rather than go into the tank, a gummed up tank check valve… how’s that to start.
Is the compressor sucking in air in the intake?
porter cable cfp23400s – will not shut off

builds up presser but will not shut off .? put new presser switch on still the same.

Don, builds up pressure past the normal cut out pressure level, keeps running, and then the PRV lets go?
If that’s the case, it is the pressure switch that is the issue. It is the pressure switch that shuts off power to the motor when the pressure in the tank reaches the cut out pressure level. If the pressure in your tank passes the normal cut out level and the compressor keeps running, then it is the switch.
However, if the compressor keeps running but the pressure in the tank never reaches the cut out level, then you need to read the pages linked from TROUBLESHOOTING / compressor will not build pressure.
I have a porter cable c2005 compressor that starts and runs but almost immediately shuts off. I can start it a minute or so later and the same thing will happen.
Have you checked the brushes?
Sounds like some sort of overload.
There isn’t a thermal breaker listed in the parts, but if there is one, it could be bad. If the brushes are OK see if you can find a breaker in or near the motor. It will have two wires on it, if it’s there.
