Compressor will not build pressure over 40 psi
by paul
(winfield, mo.63389)
HUSKY 22 GAL WL660500AJ will not build pressure over 40 psi and continues running.
I read the troubleshooting article and not sure if it applies to me.
Turned compressor off, no leaks. Holds the 40 psi for days. Thought tank gauge was broken, replaced it. Same problem.
I bought this compressor for $50 used, and many parts appear not to be original.(30 ft elect cord, tank gauge placement)I am not afraid to sink a little money and time into it. I have a pump/motor on order. Any other suggestions. pump is WL390002AJ. I should probably shorten the cord, but how much? This is a small motor/pump maybe 1 or 2 hp.oiless. Appreciate any suggestions CH also has similiar version.
_______________________________________
Paul, that the tank holds air tells me that the check valve is working.
Unplug it, drain the tank, close the drain, and plug it back in. Now, if you can pull the intake air filter, feel the port to see if you can tell if it’s pulling air in, or pulling in and puffing back out.
If it is puffing air out the intake port, then you have a valve problem.
Let me know if this helps via a post to this thread, please.

Husky 30 gallon quiet series has no pressure build up
by robert
(redding ca)
my husky 30 gallon “quiet series” turns on when plugged into the wall but it will not fill up with any air or pressure.
_____________________
Do you get any pressure build up at all Robert or it just runs with zero pressure build?
If you pop over to the site map page under troubleshooting and follow the links to the page about why air compressors will not build pressure, you will see some checks you can do. Do them, and then add a comment here with what you found, OK?
husky 2.5 compressor is not building pressure
by Pedro
(san jose ca. )
Doesnt want to build any pressure zero husky 2.5 gal. still new only a few hours ,it huuums like a vacume cleaner it realeases the air
____________________________________________
Pedro, are you saying that your air compressor will not start, and just makes a humming sound instead of pumping air?
And, please, what do you mean by “it releases the air “?
Please post your responses as a comment here so I can follow the thread.
Cheers,

My Husky Compressor Wont Build to Shutoff Pressure
My husky compressor just keeps running, up to about 60 psi in tank and then wont go higher. a week ago it would run to about 90 psi and keep running no higher pressure.
does not leak out when off, holds the pressure pretty well for week or so.
what is wrong? should i just trash this thing?
_________________
Well, whether or not you trash it depends on how handy you are, whether you have time to tear it down and rebuild it if necessary, and if the cost of air compressor parts necessary is higher than you wish as compared to the price of a new air compressor.
You don’t indicate the model or the age, but if you’ve gotten good life out of it, and don’t want the hassle of repairing it, keep the usable parts (pressure switch, PRV, gauges, regulator, etc.) for spare parts and get a new air compressor.
See the sitemap page under troubleshooting for a link to a page about why an air compressor runs but stops building pressure. Do the checks. That may help you decide.

I have a 30 gallon portable compressor (model C303H). It goes to 175 PSI, but recently started plateauing at 150 PSI. There aren’t any leaks in my airline / connection. I just purchased it from Hone Depot at the end of September. I’ve used it maybe 10 times. Any suggestions on how to get it over 150?
It also takes longer to get up to that psi. I just started having issues with it. Appreciate any insight!
Bummer. It’s still in warranty, if you bought in September. Maybe. Take it back if you can.
If not, for whatever reason –
Does it hold whatever pressure it gets to for at least hours? Or not?
Builds pressure then blows the o ring on the outlet to the tank at 40psi
You mean the quick connect coupler? Replace it.
Otherwise need model, or better model and pix showing which o ring.
20 gallon 175psi compressor. It doesn’t shut off it runs and it slowly bring up pressure to about 50 then the line in the picture blows that o ring where the hand is pointing and it will run and run cause the air is escaping
That really shouldn’t happen. Sounds like maybe the o ring is too thin,
Is this a new problem? That is, has it worked for you before?
Can you give us a pic of it, blown? And also disassembled? There’s supposed to be a grommet in the head right before the o ring.
This is the C201H, right?
Yes C201H. Attached are the oring pics and where my finger is pointing there is an excessive amount of air coming out . Like I said new o rings installed. Compressor fires up runs, tube gets extremely hot, fills very slowly and at the 50-55psi mark the o ring fails and of course the compressor keeps running cause air is not building anymore
It’s blowing out at the pump end, right?
Where are you getting these o rings?
Are they .301ID X .070 WIDTH ?
Have you checked the check valve? If you get it going and pump up to say 30psi, and stop it, does hold the pressure? If not the check valve needs work.
Yes it holds pressure for a little while.
It should *STILL* be holding within a couple pounds of whatever you put in. You’ve got a tank leak (drain valve?) or the check valve needs work.
I have a Husky air compressor. It holds air to 50 PSI only and does not shut off. It is a 135 PSI Cap., 1.5 horse built in 2007. I replaced the two gauges and the increase/decrease pressure control knob. What’s next?
If it’s oil-less, probably the piston ring is shot. Or some other leak.
Otherwise, if you haven’t got a model, can you shoot us a few pix?
It is a Model H1506FWH
Well, turns out you just have to remove the cover to find out if this is a type one or type two. They are quite different internally. From what I can tell, you have a type 1. Next step is to let it pump to whatever pressure it gets to, turn it off, and look for leaks. If you don’t find any leaks, it’s almost certain it’s the pump, specifically the piston ring and/or sleeve. It’ll be torn or folded over somehow weird. Have fun and good luck. P.S. – The regulator knob and gauges have nothing to do with… Read more »
I have a Husky air compressor model Y1000. It was working fine but then I loosened the drain plug & drained it. Screwed the drain plug back in but now it does not build up pressure. It blows air out a hole in the middle of the drain plug. What did I do wrong? I did lay it flat on its back instead of just tilting.
Not likely you did anything wrong.
“Screwed the drain plug back in” Not sure what this means, but if you could send a pic of the plug, so we can see if it’s what it probably is, that would help.
The unit is said to be not serviceable, but I daresay you need to, and can, replace that valve.
If rust or other crud came out, you might try opening and closing the valve a time or three – might just have junk stuck in it.
got it fixed. I fiddled around with the plug and then
it started to build up pressure.Thanks
OK, cool.
Thanks for telling us.
I have a husky 3 gallon compressor that builds up to 80 psi but does not go above it. Turn the compressor off does not leak and holds pressure fine but am boggled on what to do. It has a 1.5 horse power motor and is supposed to build up to 155 psi.
Model?
H1503TP
OK. Given your symptom, the possibilities are piston ring, drive belt and valves, in that order. The ring may be cracked or just worn out. You may be able to see it and tell by looking into the cylinder from the bottom. There’s a sleeve too, so if the ring is bad, you may need to replace the sleeve, too, if it’s damaged. You can replace the ring by removing it from the bottom, but if you need to do the sleeve, you’ll have to remove the head. You may have to buy a kit to get the ring, so… Read more »
My Husky 33 Gallon air compressor C331H model continuously runs and still the air output is lower than normal. Can someone helps me what to do. Thank you
You can start by using the trouble-shooting section of the manual.
If you don’t find the problem, tell us what you checked and we’ll go from there.
I follow the what the manual said in trouble shooting but still the same problem.
Angel, as I said before:
If you don’t find the problem, tell us what you checked and we’ll go from there.
I have a 55 psi tank. The motor sounds weak at times then gets louder. This happens on and off. I just started hearing a squeaky noise from where the belt is. Is there anything i can do to be proactive before ot goes bad?
Sure.
If there are maintenance suggestions in your manual, do that.
If that doesn’t help, or wasn’t included in your manual, check the pulleys for tightness on their shafts, and that they are aligned with proper tension.
If the belt is shiny or frayed, start looking for a new one.
Anything beyond that, if that doesn’t reveal the problem, we’ll need a Model number.
Good luck.
My twin head air compressor not pumping 30psi no leaks one head puffing out air. I read above comments may be a valve; what and how to replace it .
Thanks Bobby
Depends on the model of the pump. Got a model for the whole unit?
Failing that, send a couple pix of it and we’ll take a stab at it.
Model C302H
Right head puffing out air instead of in
OK, V-twin pump. Unfortunately I see only the whole pump as a “part” for $200. You need to remove the head that’s puffing. Inside you will find a valve plate – there are a few different ways to make these, so if you see something bent and either not flat with the plate, or something holding it/them open, that’s the problem. If you’re lucky, it will be a foreign object stuck in it, Not so lucky, it may be something broken or even missing entirely. If you can’t figure it out, post some pix. In fact, even if you can… Read more »
The valve plate was opened turned it upside down and reinstalled it, worked for 5 minutes and started puffing air back out. Can you buy just the new head or do I have to buy whole twin head compressor?
Had a Sears for 30 years no problem, had this husky to retire on busted after a couple of years if pump for 200. Dollars think I’ll just buy for sears.
Further research turned this up:
VALVE PLATE ASSY PXCM201/E108131 SERVICE $41.78
Here:
aircompressorpartsonline.com/valve-plate-assy-pxcm201e108131-service-e108160-p-1046081.html
You can do your own search for it, too; it may be out there somewhere else for less.
Or, do your research, and buy a different (probably oil type) pump or compressor system.
It’s a good thing the pump is not integrated with the motor, repair-wise.
Good luck.
I had the same problem right side valve plate had a piece iof what looked like crispy black plastic almost like carbon buildup. Can’t tell you if this fixed the problem due to while removing the head broke the aluminum cross pipe flare. Could you please provide me with that part number don’t need the heat sink just the aluminum pipe.
Cody, please google (or Bing, or whatever) “c331h parts” for resources…
My husky has for the second time burned up the compressor motor. Is there a known issue?
Some times that’s operator trouble, but it could be an issue with the machine.
Trouble is, we have no idea what you have…perhaps you could give us a model number?
my husky it is a 175 psi and it will not stay and it will drop to 160 in an hr and when i set to go to put pressure above 55 it will not go any further
Couple of things, Heather. You say that it loses pressure when it’s stopped, and it drops to 160 PSI in an hour, yes? If the pressure won’t get past 55 PSI, how did the tank pressure get to over 160 PSI? If there is no leak in the plumbing then the pressure drop can be attributed to a leaking tank check valve perhaps, and that needs to be checked. So, the tank is empty, the compressor kicks on when you plug it in or turn it on, and then the tank pressure rises to 55 PSI and then the compressor… Read more »
Heather, the 55 psi sounds like a bad regulator, if I am correct thinking you’re saying the tank pressure gets to 175 OK, but then drops off, but the regulator pressure won’t go over 55. Or possibly the gauge is bad. Maybe you can swap or replace it to check; Or, if you have a truck tire or something that takes over 55, but a tire gauge says it’s only 55, that would be another way to check.
Got a model number for it?
Anyway, good luck.
