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.

Bill says...

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.

Reset switch or thermal
by: Gary

Come to find out there was a wire running from the reset switch to the back of motor, the red wire, and it was shorting out. The plastic coating being frilled or melted, not sure which, looks like it been chewed up. I do not know why this is the only one like it but I put some shrink wrap on that to keep it from shorting out.

Black reset button keeps popping
by: Gary

Mine does the same thing and I replace the reset button twice and it still doesn't help I do not know what the problem is

I have heard it has something to do with the little release valve on top but I'm not sure if that's my problem or not but every 10 seconds from the minute I cut it on Pops to reset and he has done this ever since I bought it brand new and seems to be getting worse

I used to be patient and just keep resetting it resetting it until I got enough air in the tank the use it but now it's so much more hassle than what it's worth

I wish someone could figure this out and let me know thank you have any suggestions let me know Gary

Overload keeps kicking the compressor off

by Dudley
(Montgomery, tX, usa)

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


Bill says....

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

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?

Reset button pops prematurely.
by: John

21 gallon upright CP compressor. Reset button pops at cold startup after about 20 pounds. It is plugged into a good wall outlet, that is not the issue. It is not overheating. Seems like the reset button is weak or worn out. Where can I buy a replacement?

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?
