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.

Reset button is easily visible on this compressor motor.

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?

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

Please advise.


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 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?

I have a Central pneumatic 2.5 HP 21 Gal vertical 125 PSI Max. On Cold start it will pop the breaker on the compressor. The only way sometimes I can get it going is to cover my hand over the airfilter and it sucks pressure and the starts up. It did this the first week I had it. I thought it was a fluke. Now its happening more often. I’ll have to reset it four to six time then it will start. Any suggestions? It has its own 20 amp breaker.

I have the 21 gallon vertical central pneumatic air compressor and it has tripped the overload frequently in the past, especially if using an extension cord. Recently it will not reset at all. Any ideas why it will not reset? I do not use an extension cord.

I have a 21 gallon central pneumatic air compressor. I have had it for 12 or so years. After it gets to 20-30 psi the reset switch pops. It has been plugged into the same outlet for years. Even after first turning it on it runs for about 30 to 45 seconds, the reset switch pops and the head already feel very hot to the touch.

I have already replaced the run capacitor. (Added this line to this post from a subsequent post by John – Moderator)
