Husky portable compressor runs for 3 seconds before stopping

by David
(Hendersonville, TN)

I have a 17 gallon Husky compressor I bought from Home Depot. It will run for approx. seconds when I switch it on before stopping. I can switch it off thn on again and it will run for 3 more seconds before stopping. Could it be a faulty pressure switch?

Possibly, David. But it could be other things as well. As a comment here, tell me how old the compressor is, how used it is, how long the extension cord is that you are using... anything more about the conditions of use.

If you have a multi-meter, try to start the air compressor with the tank empty of air. If it starts and runs for the 3 seconds then stops, use the meter to check for power on the motor side of the switch to see if it is the pressure switch shutting off that's stopping the motor. If power is still flowing through the switch, then possibly it's the power supply, the capacitor or a motor issue, not the switch.

Cheers,

Bill

Portable Husky trouble - the extension cord we use is 20 feet long
by: Anonymous

Bill - the compressor is approx. 5 years old and the extension cord we use is 20 feet long. We use the compressor mainly for airing up tires and occasionally running a small air wrench.

Could be the extension cord is the problem. Same problem if you plug it right into the wall socket with no extension?

Did you check the pressure switch to see if that was what was shutting off the compressor?

Wiring for 4.7 HP air compressor

by Chad Horton
(Baton Rouge, LA)

I have wired up my 80 gallon, 4.7 HP air compressor per the specifications provided and it is not running.

I checked all connections and they are all hot.

I put the compressor in auto and it doesn't come on.

The other day I plugged it into my 5000 watt generator and it came on, but come to find out the generator is not rated for 30A, so the generator would trip.

I know the compressor works. I can't figure out what I'm doing wrong. please help. You can contact me at chorton@mjwomack.com.

Running the air compressor from a too small generator could cause a problem with the start or run capacitor, and the motor, Chad.

If you are getting power past the pressure switch to the motor circuit (with the air tank empty so the pressure switch has tripped) then you need to check the caps next, and then the motor.

See the page on this site about how to check the capacitors for your air compressor.

I have a H1506F Husky Compressor that is not fully building pressure

by Jim Reith
(Southbridge MA)

ok, this is a little different than the previous ones I've read here (great site BTW)

My compressor will run and build pressure but at about 80PSI is continues to run but stops adding pressure. Sometimes it will go to 90psi, but sometimes it just stays. In any case, it never builds up enough pressure to cycle off.

it used to cycle normally but no longer.

Also, I can smell a burning rubber smell if I let it run this way too long so I manually cycle it.

Where do I start and what can I look at to verify the cause before ordering random parts and wholesale replacing things?

I was hoping from the smell it was a slipping belt but I now know there isn't one from looking at the manual found here.
_________________
I'm guessing that the smell is as a result of the air compressor running too long without shutting off on cut out.

Since the pressure in the tank now never gets to cut out, the compressor will run, and run and run until it self destructs or goes off on thermal cut out.

Pop over to the troubleshooting section on the sitemap page and read the pages about why air compressors run but stop building pressure. There are some checks there.

Please add a comment here if you are still stumped after reading that info.

Cheers,

Bill

What do the two air gauges tell me?

by Jim
(Florida)

just bought used 2 gal "quiet operator" what do the two gauges tell me ?
__________________
Jim, that info is here on the site already and in a number of places.

One of the gauges tells you what the pressure is in the compressor air tank and the other tells you what the pressure setting is on your pressure regulator.

Have a look at the pages on these items if you aren't sure what they are about.

Cheers,

Bill
