Porter Cable C2005 won't stop building pressure

by James
(San Diego, CA)

I have a 5 yr old Porter Cable 6 gal pancake compressor (C2005). Recently is started continuing to build pressure until the safety valve blew and released air.


I swapped out the safety valve for a new one, but the same problem continued. I looked on your website and noticed that it's likely a faulty pressure switch. So I just ordered a new one and installed it (piece of cake).

I tested it out again, and the same problem continues. It builds pressure continuously and won't shut off. It usually blows the safety valve around 150 psi.

Do you have any other thoughts on what it might be? Could it be that I received a faulty replacement pressure switch? I look forward to your response.

Problem Solved
by: James

Thanks Doug!

I just remembered that I initially thought the problem was a bad PRV, so I replaced it with a 150 PSI PRV. Fortunately I held onto the original factory one and just noticed it was a 167 PSI PRV. I put the factory one back in and the compressor cuts out on it's own (at 155 PSI). So the replacement pressure switch I bought actually solved the problem. I appreciate everyone's help.

PRV
by: Doug in s.d.ca

This compressor is supposed to be 150 psi, so if the valve is letting go at 150, it's under-rated - should be around 160 - 170 marked on it...

Maybe hold the valve closed and see if it cuts off at 160 or so. DO NOT use a plug or other means if it shuts off at somewhat more than 150, get a proper prv.

Multimeter to test power
by: Bill

You need to check your multi-meter manual James. It's pretty straightforward, yet I don't know your make or model, and as such, better to use the instructions that came with it, or you download from the net.

Multimeter test?
by: James

Bill,
I have a multimeter, so I could give that a try if you wouldn't mind providing me a little direction on how to go about it. I'm handy, but admittedly haven't used this multimeter much. Thank you.

C2005 won't stop building pressure
by: Bill

James. Can you use a multi-meter to check if there is power on the motor side of the pressure switch when the pressure in the tank bypasses the normal cut out pressure?

If there is, then the pressure switch is not toggling off and either it's the wrong switch (incorrect pressure range) or it's failed.

Please advise.

This is a question,and then a complaint - Porter Cable C2005

by David
(Vallejo,Ca.,U.S.)

I'll start w/the question.is there a website that could show me the wiring layout for this mod.?

And now the complaints.

1)The design of the motor casing,it's an outright pain in the hoo-hoo. Not service friendly at all, and it probably wouldn't hurt to paste a diagram of the motor and electrical layout inside casing as well.

2)Would it kill the company to leave a little extra length on the wires and hoses?

Porter Cable c2005 - what air hose, connector, and coupler to buy


I have a Porter Cable c2005 air compressor. I need to buy a hose, but I don't know what diameter hose or other items I need.
_______________
All of this is covered amply on the pages to do with couplers and connectors, hoses and tube.

The air hose can be as big as you want. Since I don't know what air tools you plan on using, it's hard to help you decide what size of hose. I would suggest for many applications a 3/8" air hose would suffice.

I have added a couple of links below to help. Recognize that if you buy a coupler connector kit that isn't the same as the one on your compressor, you will need to replace the discharge coupler so that the new connectors fit.

Air Hose



Couplers & Connectors




You will want to have a number of connectors to thread into your air tools, as then, when you want to use an air tool, you won't have to keep changing connectors from one tool to another.
