Kobalt model 232177 - runs and shuts off. Won't build pressure.
Runs for a 5 seconds then cuts off...then every once in awhile to will hit for a second or two.
A bit more information, if you could.
What's the pressure in the tank? When the compressor runs for a few seconds, is the tank empty, or is it at full pressure?
What do you mean that it will "hit for a second or two"? Does this mean that it starts and runs for two second then stops?
When it stops, does it "unload"?
Maybe we can figure it out if you can give me more info.
Kobalt Pump - it fails to build pressure
I was given a 30 gallon Kobalt compressor unit. The owner knew nothing about it so I do not have a history on it. I plugged it in and it pumps fine to between 63 PSI. the motor seems extremely loud but never hearing it before I can't say. Once it reaches somewhere in there it fails to build pressure. I tore it down to see what I could find. I found the air intake hose was completely melted on the end and bent in half restricting air greatly.
I cut the hose and put it back together hoping that would fix. it would then only pump to 55 PSI and fail to build pressure. the motor sounds the same. Tore it back apart (even further this time and found the valve (see picture) on the exhaust side had damage. My question is if this is most likely the source of my problems and what these are made out of. There is daylight visible between the valve and valve plate but would this be enough to not let it build more pressure? Thanks
Hey Randy. Good for you for tearing you compressor down so far.
On this page is a link to the many reasons why a compressor won't build pressure. It looks like this...."I've just added a page that summarizes many of the answers about why a compressor won't build pressure. That page is right here."
If you haven't yet, have a read of this page.
Also, when you are seeing the valves in an non-energized state, you really can't see what's happening under pressure.
Once the pressure reaches the point where they can't resist the pressure, leaking valves will simply ingest and expel air as the compressor pump cycles, and the air pressure won't rise further.

Kobalt fails to run to refill tank
by Jim G.
I have a Kobalt 5.5 Gallon 232177 that will fill correctly to 135 PSI. When it tries to kick back on to refill the tank the engine cannot start back up. You can hear it trying to start but it fails.
To bypass the issue I turn the unit off then empty the tank. Then the unit will fill back up to 135.
My thought is the start capacitor but I am not sure since the unit does start up after I drain the tank again.
Jim. Check out the UNLOADER VALVE page. It sure sounds to me as though this is your problem. Let us know by comment here, OK?
pressure builds to approx. 70 psi only
(Fort Walton Beach, Fl)
I have a Kobalt tank/compressor unit p/n VLK1582609 s/n F23114093A.
The unit has approx 50 hours usage without any problems till now--
Suddenly it won't build past about 73 psi. Motor continues to run, no difference in motor sound,no leaks that I can find. Is an electric compressor--any ideas??
While there are many issues with an air compressor that could result in your compressors symptoms Mike, it is only 2-3 that are the most common.
So, check the most common first.
See troubleshooting and follow the link to the page about why air compressors run but don't build air pressure any more.
