Husky wl650702aj - pressure won't go above 60 PSI - shuts down

by Jason
(Dyer, IN)

I have a Husky wl650702aj 26 gallon 1.5 HP air compressor. The compressor fires up and fills the tank to about 60 PSI then shuts off completely. The motor seems to bog down around 60 PSI. I have replaced the pressure switch with a new one and that did not help. Also I thought that the pressure switch was just set at a lower pressure so when it shut off at 60 PSI, I drained all the air out of the tank to see if the motor/compressor would kick back on but it doesn't. I have to wait 20 to 30 minutes until the motor would work again. There is a sticker on the compressor that says if you want to reset the internal circuit turn it off for 20 minutes and the circuit will be reset. So I am thinking the internal circuit has something wrong with it maybe. So if anyone has any idea what I can do to fix it please let me know.

Same Problem
by: Chris

Take your cover off. There is a half inch copper pipe. There are two red ferrels ( like gaskets or o-rings) see if they have denigrated like mine did. It would only leak if the compressor was running, since the pipe is on the discharge side of the pump. Hope this helps.

HUSKY 5.5HP WL650702AJ
by: Anonymous

I too have the 26 gallon Husky HUSKY 5.5HP WL650702AJ air compressor. The internal heat protection switch cuts out shutting off the motor until it cools . I can get the compresor to pump the tank to 125 lbs but it will take 4 fillings stopping to allow the motor to cool. Is there a way to clean or replace teh internal heat sensor???? ANY ADVICE WILL BE GREATLY APPRECIATED

Husky air compressor connector / coupler question

by Alisha
(lousisiana )

I broke the main part that connects to the hose. I'm trying to figure out what that part is called so i can find one or order one.

Hi Alisha. Real nice to hear from Louisiana.

The end of the hose will have a connector on it, and the other end will have a coupler on it.

The connector on the hose inserts into the coupler on the discharge line from the air compressor.

Each of your air tool appliances will have a connector installed into the air port of the tool.

That connector inserts into the coupler on the air hose.

Your definition isn't too clear. Consider getting my eBook on The Home Compressor which goes into great detail about how things connect up to your home compressor.

Or, read this page to understand more about couplers, and then read this page to understand more about connectors.

I think either of these two is what your question is about.

Cheers,

Bill

Husky struggling building up air pressure

when the motor turns on, it has a hard time turning the fly wheel of the compressor, it seems to bog down on the motor. i have changed the motor (correct size) but it still is occurring. while running the motor works fine but it tends to want to almost stop. the belt is not too tight and it is aligned correctly. please help

Husky compressor will not build up pressure

Bought a used Husky 6 gallon compressor, worked just fine when I bought it...took it home, it set for a week, then turned it on, would not build up pressure beyond 26 psi, any ideas?

Hi there. Yup, could be a number of things that are preventing your Husky air compressor from building pressure in the tank.

Did you read the page about the things that might cause this symptom? If you could let me know as a comment which of those you've checked, it would make dialing into the problem easier.

Cheers,

Bill

Pressure Switch Releases Air
by: Cody

Hi Bill,
I have a Husky Pro 30 Gallon Compressor model VT6315. Recently we painted our fence with it and was running at 100% duty for probably 6 hours. It did great but now it seems that the pressure switch leaks out the air when either in the OFF position or after it reaches 125 PSI and shuts off. I ordered a new switch (CW209000AV) and received it today and installed it. Same issue! I don't under why the pressure switch itself would release air in the OFF position or after it shuts off when it reaches its pressure setting.

Where is releases the pressure is right were the plastic line goes in to the pressure switch.

Thank You

Cody

Hey Cody, sorry you bought a pressure switch for nothing. Keep the old one as a spare, as I suspect there is nothing wrong with it.

What I believe you have is a problem either with the compressor tank check valve leaking, or the unloader valve is not working properly.

I suspect that your tank check valve is not seating properly, and when the compressor stops, all the air in the tank bleeds out the unloader valve which is, properly, open at that time.

Check the tank check valve first, and then, if the problem persists, I would look to the unloader valve to make sure it is working properly.
