kobalt compressor won't shut off

doesn't shut off when requested psi is reached

I'm curious, does it continue running until the PRV pops open, or does it stop automatically at a higher than expected point?

If it does stop automatically, but at a higher pressure than expected, does it stop at the same pressure point every time?

If it runs until the PRV pops open, don't use it again until you replace the pressure switch, and the problem is gone.

If it's stopping consistently at a higher pressure than expected, that might indicate nothing more than an air gauge that's failing, or it might mean that the pressure switch is failing, or both.

Maybe let us know by posting a comment here?

Cheers,

Bill

Kobalt 1.5HP, 10 Gal won't shut off
by: Anonymous

pressure keeps building into the 130psi range then releasing the pressure relief valve. settings on the unit are at 40/90 as it has a dual uses.

is there a simple fix? a switch needing replaced?

If cut in pressure is 40 PSI and cut out pressure is 90 PSI, and your air compressor is reaching 130 PSI, it is your pressure switch that is not working.

Compressor builds pressure but trips reset button on motor.

by Brad Beal
(Lafayette, Louisiana)

Kobalt 60 gallon air compressor

Kobalt 60 gallon air compressor

I have a 60 gallon Kobalt compressor about 4 years old.

It will build pressure as it is suppose to but when it goes to shut off it starts shattering then shuts off.

Once the pressure has dropped it will not start automatically,

I have to push the reset button on the motor and it starts. Does this every time. Ive checked the wiring and connections and everything looks ok. I have it wired to a 30 amp 220 volt breaker.

Any idea what may be causing this.
____________________
Brad, the shattering you refer to, is this sound coming from the pressure switch? If so, your pressure switch points may be worn out and it's time for a new one of those.

As to having to push the reset to start the air compressor, that suggests that the motor is overly warm, assuming the reset you refer to is on the motor.

Why is the motor overly warm, if that's the case? One thing is that your air compressor is taking longer to fill to cut out pressure than it used to, the motor is running longer as a result, and that's overheating it a bit.

More likely though, the issue may be capacitor related. A weak or failing run cap would mean that the motor is running under powered, and that leads to overheating.

So, check the pressure switch, and see the page on this site about how to check a capacitor.

Pop back here and add a comment with more info if you wish.

Cheers,

Bill

Complaint - Kobalt 37296 aluminum piston housing cracked

by Saxman
(Oakland,Tn)

Kobalt compressor model #37296 aluminum piston housing cracked in two.

Ditto from other posts.

Limited usage but was out of warranty.

Kobalt has replacement for $148.43+ $50 shipping but for something that is clearly defective is not worth it.

No satisfaction from Lowes either which causes me to reconsider buying from them in the future.

Also unit was extremely LOUD!!

If this an example of Kobalt quality and customer service I will not be purchasing any of their products.

I understand your frustration about your Kobalt compressor.

Not just this one, but all brand low cost compressors are rife with quality problems, plus no real network for supports and parts.

Most folks that are DIY or small workshop air compressor users cannot justify acquiring an industrial air compressor that provide support and parts, because of the up-front costs.

Between a rock and a hard place sometimes.
