Brand new Husky Air Compressor reads 15 psi low on gauge

by cpo
(Denver)

I have a 26 gallon compressor with a max 150 psi. The manual says it cuts on at 120 and off at 150. However, the actual gauge reading is showing about 105 on and 135 off (15 lower on both ends).


I live at 6000 ft. but I have had other compressors that show 150 on the gauge when max is 150. Is altitude a factor in regulator switch cutoff or gauge readings?

Altitude is a factor in defining SCFM, as it is related to altitude as part of the definition.

It's just a guess, but I wonder if your gauge is reading PSIA as opposed to PSIG. In PSIG your gauge automatically compensates for atmosphere (14.7 PSI) while a PSIA gauge reads actual PSI?

i have a husky h27508uwk that dont build up pressure quickly. i did replace the reed valve asm with the upgrade version. the old valve had a broken middle reed. after replacing the valve it still doesnt build pressure up that much. there is air in the tank. my guage slowly climbs but my regulator guage shows nothing. also to check if air pesur is sufficient from the piston head, i disconnect the air outlet tube and was able to block air from coming out of the piston head. can i do this? or is something else not right here. i would think that you can stop the air

Great thought! You may be right.

Interesting thought on the gauge type. With the variance being at approximately 15 on either end...that would be the most logical solution. I might add that the same variance was identified on both the tank gauge and the regulator gauge.

I tried and tried to resolve this issue. (I bought the air compressor the same day I realized the issue). I called the service number in the manual (MAT) and they gave me a number for Home Depot support, who gave me another number to someone else who ended up having no idea who made my air compressor. This particular model is made in China, yet nobody claims ownership. Not a good situation for trying to make good on a one year warranty. In the end I took it back to Home Depot, a different one than the purchase location. They pulled another one of the same type off their floor and identified the same variance. I ended up returning it and going with a Dewalt compressor. At least I know who makes that one should I ever have a problem! : )

Of course, if one were still interested in the Made in China Husky, I suppose it would be simple to put another gauge on the line to see how it compares...because your thoughts make the most sense of anything else I could come up with. Regulator is even labeled 120-150, as is the tank tag.

(FWIW, the Dewalt is working well...and seems to cut out at just over 200 like its supposed to.

Husky hs7810 - Oil in crank case

Oil in crank case getting pressured up

Howdy;

Is there not a fill tube for the oil sump, and doesn't have a vent in the cap? Check that to see that air in the sump can both escape and enter as needed.

You may have a piston ring issue.

Cheers,

Bill

Husky 26 Gallon won't restart

by Blaine Meyer
(Raleigh, NC)

Recently my 26 gallon Husky vertilcal compressor has developed a problem. It runs fine and builds pressure to the correct psi, about 135psi, then shuts off as it should.

After using an air tool, say an grinder, the pressure drops, the compressor starts up and re-fills the tank.

After a couple of re-fills, 2 to 3, the compressor won't restart and refill the tank. The motor will come on for a second or two and it sound like the compressor wants to start but it doesn't and this continues about every 10 secods.

I just replaced the pressure switch with a brand new one and I checked and cleaned the check value which looked ok.

The compressor has had no problems up until this recent issue. Any ideas ?

Sure. A couple. Next time it won't start for you, do this.

Pull the plug, open the drain, and drop the pressure to zero PSI.

Close the tank drain, plug it in and turn it on, if yours offers that option. What happens?

If it starts, and runs up to cut out pressure, listen for the unloader valve to work. If it does, then unplug it, empty the tank again, and start it again. Does it fill to cut out pressure? Does the unloader valve work?

Give me a heads up as a comment on this thread if the above does or doesn't do anything for the problem, K?

Problem Solved
by: Anonymous

Bill,

Sorry for the delayed reply but I solved my problem. I read the instruction in your reply and when into the garage to start troubleshooting my problem. At one point I was about to unplug the compressor for the extension cord I use and I had the end of the cord in my hand and I could feel the cord's built-in circuit trying to open and close. Thinking it could be the cord I replaced it with another extension cord I had and no more problem. The compressor has been running fine ever since.

Thanks for replying to my problem

26 gallon Husky compressor won't start when the motor is warm

by Fred
(Andover, MA)

I bought a new Husky 26 gallon upright air compressor from Home Depot. It starts and runs fine, if I start it when the motor is cold. But once it stopped, either when it reaches the setting psi or when I turns it off manually, it won't start again. I have to wait for 7 or 8 minutes until the motor is cold, then it will start again. Actually, the motor tries to start for a few seconds and failed right away. I touch the heat sink area and it wasn't hot at all, just a little bit warm. If I don't let the motor stop, then it will run continuously without any issues.

Any ideas, why and how to fix this warm start problem? Thank you for your help.

Motor not enough horsepower
by: Fred

After some discussions with a mechic and more investigations, we conclude that the this model of compressor does not have enough horsepower to re-start when the motor is hot and the tank is at high pressure.

Although the case of the air compressor is only warm, the heat sink mount to the motor is very hot. If I let motor cool down OR drop the pressure in the tank(by pulling the air lease plug), then the motor will re-satrt. Otherwise, the motor will try to re-start for a few seconds and then it will fail.

We think the 1.5 HP motor is not strong enough to re-start, for this 26-gallon tank, when the motor is hot and the pressure is above 20 or 30 PSI.

Will try to return
by: Fred

I will try to return to Home Depot. I bought this a few months ago. But I can not find the original receipt. I only used this for 2 or 3 times to winterize my sprinkler system. I still have all the original packing package and box. Hope they don't give me too much trouble.

Good luck. Let us know how it turns out, if you would.

motor problem
by: Doug in s.d.ca

If this is a new machine, just take it back.

If that's not an option, I'd look at the start cap.
