porter cable pancake compressor started smoking and just quit

Its probably 10 years old i was using it and it started smoking and just quit...is it fixable?

______________________
Sure it is. The question really is, will the cost of repair be worthwhile in relation to the cost of a new one?

Your post is scarce on details. I surmise a motor burn out, assuming that it was the motor smoking. If that is what was smoking, what does a new motor cost as compared to a new, comparably sized compressor?

Find the HP rating of your compressor motor, and contact a couple of electric motor supply companies to help determine that.

Cheers,

Bill

compressor runs to 20psi and keepsrunning

HI, BILL ITS EMERY AGAIN, MY C2005 TYPE 2 COMPRESSOR. I REPLACED THE VALVE PLATE & GASKET KIT LUBRICATED THE CHECK VALVE AND IT STILL RUNS TO 20PSI AND KEEPS RUNNING, ANY OTHER SUGGESTIONS, THANKS EMERY

Emery, your compressor reaches the 20 PSI that you refer to, and that pressure level is causing something to happen that prevents the pressure from rising.

Replacing or repairing the valves and gaskets is one fix, as those are common reasons why an air compressor runs but does not build pressure.

Pull the intake filter and make sure it is clean.

With the air tank empty and the compressor off, remove, clean and replace the tank check valve.

Make sure you are not using any extension cord, and the power supply is clean.

You may want to check the capacitor to make sure it's OK.

If all that checks out, then I would look to the piston seals.

Cheers,

Bill

Porter Cable 150 PSI pancake compressor runs and runs

by Scott Enck
(New Ringgold Pa. USA)

Bill

Hope I am not being redundant.

Had trouble finding my way through the questions.

I have a almost brand new Porter Cable 150 PSI pancake air compressor.

It will only make 100 PSI and keep on running till the cows come home, but only make 100 PSI.

I had a leek which I fixed. I also put in a new rebuild kit in the Devilbiss compressor which included new reeds. To no avail.

Should I park the thing behind my backhoe and forget I put it there?

Thanks much.

Scott

Scott, if you read the troubleshooting section and followed the link to the page about why air compressors run and don't build pressure, much of what you need to check is noted there.

If you read the Porter Cable forum page, you would have found many, many references to this type of air compressor problem.

That your Porter Cable air compressor runs and does not build pressure is not unusual. That seems to be a common problem for many brands of lower cost air compressors.

You say you put in a rebuild kit? Did that kit include gaskets as well?

Porter Cable CPF6025VP only pumps to 20psi

Porter Cable CPF6025VP air compressor

Porter Cable CPF6025VP air compressor

It starts and runs, but sounds a lot quieter than it did, and only pumps to 20psi, and shuts off. It also sounds funny. Like a echo, hollow type sound. First thought of course was the pressure switch, that shuts it off was bad, but the running quiet, and sounding funny throws me off. Any ideas are greatly appreciated.
_________________
Mark, there are a number of reasons why an air compressor will not build pressure, and why an air compressor will shut off before the tank pressure reaches the normal cut out.

The sound change suggests to me a valve and/or gasket problem.

But, the compressor should not shut off at 20 PSI, even it that's all the pressure the pump can generate, unless, of course, it's running so long it overheats and goes off on thermal cut out.

If the compressor shuts off at 20 PSI and it's fairly cool, as in only running a few minutes, you need to have a look at the pressure switch innards to see if the pressure switch has tripped off. If it has tripped off at 20 PSI, then I would suspect the switch.

Other reasons why a compressor will not build pressure are covered on pages linked from the troubleshooting section on the sitemap page.

Cheers,

Bill

Replaced the switch.
by: Mark

Well I replaced the whole box on the side of it. Which I assume contains the pressure switch. It still does the same thing. Could the regulator possibly cause this ? At one time it was so tight I had to use channel locks to get it where I could turn it. Possibly that caused the issue ? It's actually my dads. So I'm not sure how it got that tight in the first place.
_______________
The device that turns the compressor on and off is the pressure switch.

The regulator modulates the air pressure downstream from itself and has no bearing on the start stop of the air compressor.

Typically a pressure switch turns the air compressor on at 70-100 and shuts it off 110 - 150 PSI, depending on the make of the air compressor and the pressure switch settings.

Once again, when the compressor shuts off, is there power flowing from the pressure switch to the motor circuit?

Thanks
by: Mark

Thanks for the reply Bill. It only runs a couple of mins. It doesn't seem to pump up any slower than before. Just sounds funny, and shuts off at 20 psi.

Mark, did you check to see if power is still going to the motor once the compressor stops? Is the pressure switch turning the compressor off or not?
