If the compressor runs, builds pressure and then continues to run past the normal shutoff point then the problem is the pressure switch. The pressure switch is part #N003307.
If the compressor runs but doesn't build pressure or builds to a pressure lower than the pressure switch cutoff point and won't build anymore then the piston and cylinder are worn out. The piston & cylinder are sold as a kit which is part #KK-4964.
I hope this helps with your repair!

Air Pressure bleed off Question by Jim Vogel
When compressor reaches set pressure and turns off - - air
bleeds off within the unit and will go to O # if let set long enough. Sometimes it will stop if I turn the unit on and then off
within a couple of seconds running. Whats causing?
I think the problem is the tank check valve. If the valve doesn't seal off air will bleed back to the cylinder. There is a small vent hole in the cylinder head to bleed off the air escaping from the check valve. A new check valve should solve the problem. The check valve is part #D27022 and it is available from http://www.ereplacementparts.com.
I hope this helps with your repair!

manual psi adjustment Question by boof
The plastic part inside the heavy spring that controls the psi to the tools is broken and I do not see any replacement listed for it. What should I do?
That is part of the manifold assembly. Porter Cable does not provide any individual parts for the manifold. It will need to be replaced as one unit. The manifold is part #N003001 and it is available from http://www.ereplacementparts.com.
Good luck with your repair!

no air on tool side Question by Randy Davis
What is up with the tool/regulated air side on the compressor?? I've used it maybe 4-5 times and it no longer supplies air to the tool side only to the tank side. Is it a defect??? Not to mention the product carries a hefty price tag compared to comparable products. This really stinks the product was recommended by my father in law. Is there a solution???
Assuming that the regulator is properly set then I would guess that the problem is with the regulator on the manifold. Porter Cable does not offer the regulator parts separate from the manifold assembly. You will need to order the manifold. The manifold is part # N003001 and is available from http://www.ereplacementparts.com.
Good luck with your repair!

screwhead Question by James Hoff
I have a Porter Cable compressor that quit running. I want to take the covers off so I can check out the problem. The screws look like Torx heads with a pin in the center. Is there a special tool to remove them and where can I find such a tool?
That style of fastener is called a "Security Torx". You should be able to find a driver from a specialty tool supplier. I know that Snap-On sells them and I would assume that Matco or Mac would also. You could also try a Sears store, they might have them.
I hope this helps with your repair!

manifold problem Review by Lonny Moore
I rate this product with a 0. I had big expectations and was excited about my new/used comp. I wasn't told there was a problem with it leaking until I got it home. After I learned the problem, I decided to repair the comp. When I saw the price of the manifold part I about flipped out. Not only was I deceived by one guy, now Porter Cable wants to stick it to me as well. No reason why Porter Cable can't sell us repair parts to repair this manifold. Porter Cable is ripping us off. I just need the plastic parts under the handle. Why can't Porter Cable do that for us? I did notice others are having the same problem. Why can't Porter Cable help us out? This was my first Porter Cable product and it looks brand new but unless Porter Cable can help with the solution this may me my last purchase. I believe this comp. has never been used, it was still in the box. Come on Porter Cable, you can do better than this, you just got to want too. SURE AM DISAPPOINTED SO FAR ------MAKE IT GOOD OK
The compresser will run up to 80 PSI and will not shut off.! but if i shut it off it is still holding 80 PSI and dosen't seem to be leaking air.? supposed to hit 150 PSI ?
I have the same problem but 90 PSI talked with compressor repair company local and they say it's the sleeve and ring and estimated parts price $100.00 not including labor. It's just a bad design mechanically.
motor just shut off Question by rob
I was running an air gun and the motor just shut off. Where should i begin to find the problem?
Fairly new C2002. Pressures up tank to 150, shuts off, but no (zero) pressure to outlets for tools. Took apart pressure adjustment on manifold and appears that the part that pushes on the air control (disk with a small head on it that the spring sits on) is broken. Do you see this small piece? Don't want to buy a new manifold for a 2 cent part. Works fine otherwise just no air to the tool outlets.
The same thing happened to mine, I have yet to find a replacement part. I haven't even used it yet.

same here
Used it once and now am stuck. I certainly wouldn't purchase a new manifold just to have it do it again. Gotta be a place to get this somewhere.
Response #3 Posted By Jeff
I have this same problem. I let someone borrow the compressor and they must have removed the pressure adjustment knob and lost part of the mechanism. All I have is the knob, the spring and a small nipple that goes inside - - not sure what is missing but know that something is. Anyone found a solution yet?
Response #4 Posted By Gordon Nordmark
Same problem. I purchased the C2002 with accessories last year. Never used it. Took it out of the box last month, went thru its "break-in" steps. Tank pressured up fine but no air came thru various nozzles. Turned regulator knob and it came off the threaded male housing. Only parts inside were a spring, short black molded ferrule and an O ring. I didn't see any other parts to enable release of air to the outlets. Replacement manifolds run $69 to $120 plus shipping and additional labor. Seems very unfair.
Response #5 Posted By Randy
I have the same problem and it looks like the manifold needs to be replaced unless there is a fix on it but the replacement is as much as the compressor itself is new well a few bucks cheaper absolutely ridiculous I think
Response #6 Posted By boof
The same problem. The manual adjustment valve requires that a small plastic part that is held down with a heavy spring inside seems to be broken. All that is required is that plastic part. Why can't we just get those internal parts required? This unit is less than one year old and has only gone thru the original box of nails that it came with. (Disappointed)
air escaping Repair by mark philip
air escaping out of the vent next to the piston assembly
I have about 5 pancake porter cable compressors with the same problem...they will no longer pump up and hold air. What is it?
Response #2 Posted By Mark
Hi Mark,
The problem is the Check Valve. The check valve is not sealing off completely so air is leaking back to the cylinder. There is a vent to allow the air to escape out of the cylinder. A new Check Valve should solve the problem. The Check Valve is part #D27022 and is available from http://www.ereplacementparts.com.
I hope this helps with your repair!

no air preesure Question by mark a philip
The motor works, but there's no air pressure. What should I look for?
If there is zero pressure check the drain valve and make sure it is closed. Check all of the tubing and hoses for leaks. If there is still no pressure or low pressure then it is most likely that the cylinder and piston are worn out and will need to be replaced. The Connecting Rod Kit, part #KK-4964, will replace the cylinder and piston.
Good luck with your repair!

Motor wont Question by Nelson
I have a C2002 Type 2. Pressure builds to just under 100 lbs. Will not go higher and motor keeps running. Do I need to buy the Connecting Rod Kit # KK4964 because the piston leaks?
The inability of the compressor to build pressure is caused by wear to both the piston and the cylinder. To make the repair you will need the Connecting Rod Kit, part #KK-4964. the kit includes the piston, connecting rod, and cylinder wall.
I hope this helps with your repair!

compressor kepts running Question by frank
Porter Cable compressor runs stops for 10 sec and starts up again
My Porter Cable compressor leaks air from the the head area, and there appears to be a small hole in top of the head. What's the hole for, and how do I fix the problem? It's not even a year old, and it's used minimally.
Bobby I have basically the same and was given some advice to look at the check valve going into the tank...Mine appears to be stuck so I'm going to replace it. That small hole is apparently for relieving the pressure off the compressor cylinder after it stops running... The check valve is supposed to prevent all of the air in the tank from also escaping into that hole. My first thought when I saw the small hole was it must be a casting imperfection.... Geeesh
Response #2 Posted By Pete
There is a small orange O ring type thing that is on the aluminum tube going into the head. It has a slot that the ring slides into on the tube and the top locks into the head and valve plate. Its a fairly easy fix. You will need a Torx screwdriver to open up the motor housing. Its a #25 size Torx screw. Take the head off the piston (4 hex screws) and you will see the O ring. The O ring was leaking for some time on mine because it kept on turning on even when not being used. Today it blew out and it wouldn't build any pressure. The O-ring costs $1.76. Cheap fix. Look at that first before you spend a fortune on other parts. Good Luck
Parts cross referance Question by Bones
Why is the ring replacement kit not listed on the C2002 type 3 parts list, but it is on other models compatible with it ? Dumb question, but the ring replacement kit for a C2005 type 0, is less than half the price of the connecting rod kit shown for the C2002 type 3 .
Mine has done this in extremely cold weather in Wisconsin. I believe something is freezing up because as soon as I take it inside to warm up it worked fine good Luck

Recently purchased a Porter Cable C2002 compressor. It's only 2 months old with minimal use.
I was using it earlier today. I adjusted the pressure to max as I have a stubborn bolt to remove.
When I was waiting for it to catch up with full pressure I noticed the compressor got noticably louder and it would no longer build any more pressure. So i drained all the air and started it again, It will only build pressure to 50 PSI and no higher. I shut it off and all is quiet. It's not leaking anywhere. After 2 hours of being off and not used it still has 50 psi in it.
Any Ideas what to look for?
I will call Porter Cable customer service as it is less than 2 months old. Hopefully they will help. I bought this figuring it was a good quality brand....
