My Kobalt digital air compressor ( Model No: 103797 ) will not run when its turned on. The display will go through two screens when toggled, but the compressor motor does not run. What can I do???

Hi LeRoy. The first recommendation is to go to the Troubleshooting page on this website, and click the link to my compressor will not start.

There's a bunch of tips there for things you can do to try and get your air compressor running again.

No success. Tell me what you've tried. It would be useful if you could give me your answer(s) as a comment here, so that I can follow our discussion as we try to figure out what is happening (or not happening) with your air compressor.

Cheers,

Bill

Low output air supply. Oily residue in air tank purge

by Kevin

Using a 30 gallon 1.6 HP model 221495. Working fine until today. No output air pressure. Motor runs, oil level OK.

Kevin. No output, but what does the tank gauge say?

Are you saying that the compressor is running and no pressure builds in the tank?

Comment here so I can follow the thread, please.

If the plug is melting down, then it sounds like you have a short in the compressor power circuit.

Could be the pressure switch is cooked, could be a capacitor, or it might be the motor.

When I drain the Kobalt tank a thick yellowish sludge pours out.

by dan

I have a 5 month old 5HP 80Gal Kobalt.

I use it pretty heavily for sandblasting.

When I drain the compressor a thick yellowish sludge pours out, it has the viscosity of syrup.

I am using the recommended oil and replaced the oil per the manufacturers instructions.

I also noticed that the oil is black in the sight guage; after draining and refilling the oil a few times the oil cleared up but is slowly turning black again. What could be causing these issues and should I call Kobalt about the warranty.

Thank You,
Dan

Off hand, based on your application for compressed air, I would think that you may be exceeding the duty cycle of the air compressor, and that, in doing so, you may be overheating it.

Check the specs to determine what the duty cycle is, and make sure that you are not exceeding that.

Some oil can be expected to wick by the piston seals into the tank during normal operation. Lots of oil suggests that the piston seals are worn. That, combined with whatever dust makes its way past the intake filter and into the tank along with the compressed air, combine, along with water, to make the sludge you refer to.

Check your intake filter to be sure that it's clean enough.
