Same Issue
by: Josh

I have the same issue with the same compressor. I runs at low RPM before it trips the reset. My guess is a capacitor problem but haven't had a chance to troubleshoot.

Central Pneumatic cuts out
by: Bill

My first thought would have been the pressure switch too, Tom.

However, when you say "have to keep hitting reset button to build up more pressure" that is suggesting to me that the motor is overheating.

Good that you have the 67847 plugged into a 20 amp breaker.

Tell me as a comment, do you feel that the motor is overheating?

If so, time to check the run capacitor I think. See how on the page on this site.

67847 Compressor keeps overloading reset switch

by lou

i have a central pneumatic air compressor #67847. i just brought it used.

when i went to turn it on, it would run for 20 secs then shut off , maybe building up to about 40 psi. i have to hit the reset buton to kick it back up but it wont build pressure past that. itll just run for a few then shut off again.

then i checked the fuild levels an realized they filled it past the full mark, the oil was black which was a bad sign also.

turned it on again an it reached past 90 psi but it popped the reset a couple times during that process, and sometimes when i hit the reset it will hum then pop the reset again.

the pressure switch is broken also because it'll stay on even though the lever is in the off position, what can be the problem

What could be the 67847 problem?
by: Bill

Lou, probably a couple of things.

Check the unloader valve to make sure it's working, and do that by seeing the the compressor starts OK with the tank totally empty.

While you may have a pump problem, I'd check the start capacitor next. See that page on this site.

Source for capacitor
by: Bill

If you Google start capacitor suppliers you will find many.

You need to know the size of yours, the voltage rating, the microfarad ratings, and as long as the new one has the same ratings, and as long as it fits the footprint, then it will work.

The rating information should be on the side of the old cap.

Troubleshoot
by: Dewayne

Not sure what your compressure looks like, but if you have a guard or cover over the drive, remove it (unplug copmpressor), make sure it spins over and not locked up. If it spins free, it's probably the start capacitor.
