My compressor keeps popping reset button

by John
( Greenville Mi)

I turn on my air compressor and it will run up to about 25 pounds and pop the black reset button on the side of motor, i wait a few minutes reset and it will run for about another 10 or 20 pounds and pop button again. I have had this for about 5 year and never had this problem before it would pump up to 110 pounds no problem this is a 21 gallon upright compressor.

It sounds like the compressor motor is overheating.

Assuming all is mechanically correct on the compressor, then John, I would look to the run capacitor, or the motor itself failing.

Cheers,

Bill

CP 67708 reset button pops in seconds
by: Thomas

CP 67708 new plugging in for initial 30 minute run and the reset button pops in ten seconds or less from when I turn on the unit. No pressure is built up, nothing just pop.

Need a reset switch?

by Vern Bowerman
(San Bernardino, CA)

I need to replace the reset switch as the compressor reset switch keeps popping out. I have to reset the switch in order to use the compressor and I feel that this is happening too many times. I can plug it into the wall plug and it still does it.
____________________________
Vern, does the compressor run for a while before the reset switch pops out, or is it happening on start up?

If the reset switch keeps popping, that suggests to me that the motor is overheating and that it is not the switch that is the problem, but the motor overheating that is causing it.

It would be good if you had included the model number of your compressor, and provided some idea if the compressor is new or well used. If well used, you quite likely have other air compressor problems than a reset switch.

Can you provide more details as a comment here?

Cheers,

Bill

reset switch keeps popping
by: Patrick

Hi I have a central pneumatic 3 gallon 100 psi pancake air compressor.

It's a little more than a year old. It just started popping when I hit the reset button.

I unplugged it from receptacle and waited 30 mins. And tried it again but same problem it won't fill up with air since reset keeps popping. Any advice?

Overload keeps kicking the compressor off

by Dudley

The compressor keeps kicking the overload switch and there is no indication of an actual overload. Has anyone had this and found a solution?

Overload, as in too high a pressure, or thermal overload, as in motor temp too high?

My central pneumatic will not build up air over 40psi

by Cedric Weeks
(jackson, ms US)

Compressor is only 2 years old runs great with the exception of building up air.
___________________
It is hardly running great, Cedric, if it won't build air pressure past 40 PSI.

Central Pneumatic air compressors, like any typical DIY type air compressor, can have a number of reasons why the motor runs well, but the pump won't build pressure.

That's why there is a page of information about this problem under Troubleshooting on the sitemap page. Have a look, and then add a comment here with specific information after you have checked a few things as per that page.
