Top 20 Porter Cable C2002 150 Psi 6 Gal Compressor Questions & Answers

Yes use pipe thread seal. The center is turned to open and close no need to remove plug. If is frozen replace.

they have this common problem ck out here.. https://www.youtube.com/watch?v=s5eWvRzEmuQ hope this helps.

Have you turned the knob on compressor regulator clockwise.?

indicates a failing start/run capacitor for the motor as most small compressor do not have an un-loader for the start and the motor is strong enough to start with a reduced load when the controller switches the power back on

the reed valves/ poppet valves have failed in the cylinder head /s allowing the air to continually pass from in and out with each stroke

Did you check for proper oil level in the compressor? When unit is running use ammeter to confirm power draw to make sure that it is within specs.

Could be the belt is off or the pistons are not reciprocating

There is a valve on the unit that is connected to the motor, this valve is adjustable. Look for the cover housing where the cord goes into a box that is mounted on the tank.. Some models have a lever that turns the unit on and off there. Take the cover off and see if any parts are loose. If not then there should be a screw that you can adjust.

unhook the electrical connections and mark them for re-assembly and then disconnect the lines and remove the pressure switch

There is a cheap connector where a pipe entering tank - Oring usually failure in first 3month. Advise to replace for better fitting.

Depending on the pressure in the tank when the safety valve releases,the problem is likely your pressure switch. If the pressure is at or above 160 psi when it blows, then the problem is the switch.If the pressure is lower, then it is likely a faulty safety valve. There are about 8 versions of this machine. check on dewalt service net for the correct part. you may need to check ebay if the part is nla thru dewalt.

Do you meant - your air pressure switch ? Advise - install an digital Controller and all problems with your compressor goes away. Check for Compressor Controller

REPLACE PRESSURE REGULATING VAJVE

What you need is something called a volt-ohm meter. Obtain one and use it to test your switch and wiring.

Pressure switch problem ! Replace all for Digital Controller. Check this site for solution: www.CompressorController.com

Check for internal leaks ... Some time it is simple O0ring replacement. Better to replace a fitting completely with more advance options. Or even better toinstall Digital Controller. Check this site: www.CompressorController.com

your piston compressor is weak.can also be due to the filter inlet not good.

then it is damaged and will need to be replaced. but is it one where you push it in to lock and pull it out to unlock and adjust ???

1. The regulated pressure is at the output of the pressure regulator i/e the air pressure being delivered to the air tool or spray gun.
2. This can be set from just a few PSI up to about 180 PSI (on my Porter Cable unit).

I found this it might be helpful>.Your check of pulling the line off to the tank and seeing how much pressure is being generated is a good one. You have now pretty much isolated the compressor lack of pressure as being upstream of that point.I would pull the intake filter too, and do the same check. Is it pulling air in strongly, or is it huffing air back out too? If huffing, that's a sign that the intake valve is pooched.If it is pulling air in, and air is not being pumped out, yup, it could be a sign of cylinder piston ring wear, but then, you would be getting a lot of air out of the oil fill cap which is vented. If that isn't happening, and you are getting strong suction at the intake, my money would be on an internal pump gasket blown which is allowing air to flow around inside the pump from high pressure to low, but not down into the tank.When you open up the pump, you might as well have a new valve plate and gasket kit, as both are, in time, wear items inside the pump.
