Husky compressor motor running slow - it was the start capacitor

by Matthew Howell
(Kansas City)

Husky 80 gallon upright, dual stage, 4 HP. The motor has been running slow, speeding up and then running slow.


I replaced the start capacitor and now it runs at the proper speed again. It was the one rated 340-408 MFD. Hope this helps someone else.

Husky VT 631502 AJ - I want to wire the motor for 240 volts

by Joe Rowland
(Anaheim, CA, USA)

I have a Husky VT 631502 AJ air compressor that is currently wired for 120 volts. The motor indicates that it is an Emerson Motor Division in St. Louis. The small diagram on the side of the motor indicates that the power wires for both 120 and 240 volt operation go to the same posts on the motor. It seems to indicate that I move the white wire that is attached to the number 4 post to the number 2 post and move the brown wire that is currently on the number 2 post to a blank post. I can't find a wiring diagram any where else. Has anyone wire this compressor for 240 volts?
thank you,
Joe

Husky H1506f will not shut it self off

by kevin
(colorado)

my husky H1506f will not shut it self off when max pressure is reached

what could cause this problem..
____________

Hello Kevin. When your compressor pressure reaches the cut out level, and the compressor doesn't stop, that means that electricity is still flowing to your electric motor, and it keeps running.

The compressor will then keep running until the pressure relief valve opens, and that should bleed the pressure in system down below a danger level even though, then, your compressor will keep running until something fails.

If the compressor won't shut off at the cut out pressure, it's 99% sure that your cut out pressure points in the switch are staying closed allowing power to flow to the compressor motor, and the simplest thing to do is to replace the pressure switch.

Cheers,

Bill

Compressor wont shut off
by: Howard

Most likely your contacts are stuck, these contacts are not real good with high voltage.Disconnect the power and manually pull the contacts apart if they go right back together then your air adjustment need to be readjusted, if they stay apart check the contacts for burned spots. You can sand them to clean them up but this will happen again over time. Bigger compressors use magnetic starters which use low voltage to the regulator and the Magnetic starter controls the high voltage. Howard

Husky H1506FWH Type 1 compressor, pressure switch adjustable?

by Steve
(Vegas Baby)

I have a Husky H1506FWH Type 1 compressor. It seems to work as it should, turns on, builds pressure, shuts off, cuts back in when pressure drops.

However, it is only building pressure to 75PSI before it cuts out II can see the pressure switch work. There is a 10mm bolt on the end of the switch, is that for pressure adjustment, is there another way to adjust pressure? Or do I need a new switch?
______________
If this is a new problem Steve, that would suggest to me that the switch is failing.

Yes, there are adjustment nuts on some models of pressure switch, but I cannot find a photo of yours, so I don't know for sure.

What to do? Turn the bolt one turn, start the compressor and see what's what.

Or, spend the $25 or so to get a new one, and press on.

Cheers,

Bill

I have a couple pictures of the switch, but I do not see how I can post them without starting a new questions. Ideas?

Sorry Steve. The system, unfortunately, doesn't allow photos in subsequent comments. Do start a new thread with the content from the old, and add up to four photos.

Husky E103774 26 Gallon Air Compressor throws breaker after 3 minutes

by Clark
(Katy, Texas)

I have A 3 year old Husky. After the unit has been on for 3 minutes it throws the breaker on the unit. I wait about 30 seconds before I can reset the breaker.

The motor does not have any unusual noise when it is pumping air. It just pumps along then quits.
____________________
OK, Clark. Here's what I think.

This is obviously a new phenomenon, so I suspect that you are not using an extension cord or a power bar to get power to your air compressor.

If you are, plug the compressor right into a wall socket and try it again.

Since I don't believe you are, though, I would suspect that your compressor motor is overheating as the run capacitor may be failing.

See the page on this site about how to test the caps.

Cheers,

Bill

Husky Air Compressor.
by: Clark

Bill,

Talked to the manufacturer today. On this model air Compressor there are 2 different Capacitors. There is a starting Capacitor and and Running Capacitor. I ordered the running Capacitor.

The extension cord is rated at 10 amps and the Compressor is rated at 15 amps. Guess I will need to find a new location for the compressor even though I have been running the extension cord since I have had the compressor. The cord would get a little hot after each use. :-)

Thank you for your help isolating the problem. I should get the part by next weekend.

Clark,
_______________
When the compressor is newer all components work better. That the cord was heating up suggests that you have been chronically under powering your air compressor motor and that could be part of the failure of the run cap.

Cheers,

Bill
