This problem is usually caused by the in-tank check valve. Follow the discharge airline from the pump to the tank. This line will connect to a brass or chrome valve (check valve). Easy to test. With air in the tank, pull power cord for safety, remove the small tube (or larger) at the brass valve. If air is leaking here, replace the valve with generic valve or try removing the valve and clean the seat. Good luck.

Your compressor will work in the vertical position however you will not be able to properly drain the water from the tank in this position.

I have model Husky WL651004AJ it will not run at all. I want to remove the top cover to check the electrics. I can get the cover off. The snaps come loose, that's as far as I can get. How do you remov

I have a Husky WL651004AJ which has not been starting up for family members lately and noticed a 50 ft extension cord was being used because of the distance from the power outlet. I moved the air compressor to the power outlet and plugged in the power cord without any other extension cord and the air compressor works fine. The 50 ft cord was too light duty for the power required.
(12 ga) and min gage of 10 for the distance of 50 ft without disrupting the power breakers.

Husky Air Compressor problem is the compressor will not shut off after it reaches the shut off pressure it keeps running? checked and supply tube clear....

Replace the pressure shut off switch.First drain the tank and shut off all power.Remove switch and inspect for any debri or water in the tube to the switch.
Also check the settings.max i think is 150psi.So it should fill to say 145 and shut off.

I have a Husky air compressor model WL651004AJ. The problem is that it builds pressure initially up to 75 psi then shuts off. I have to turn off the power switch, wait about 5 minutes, turn the switch back...

It sounds like you need to replace the run capacitor , if yours is weak or defective the motor will overheat. Check "Drillspot" for a replacement. Another major cause of overheating is due to a dirty air filter , you should check it first.

While using my compressor (Husky WL65004AJ) the compressor used to go on when the pressure dropped down to about 85-90 psi. Now it doesn't. The only way that I can build up the pressure again is to shut...

Hi and welcome to FixYa, I am Kelly. I tried several places too cross this model number: WL65004AJ without success. The pressure switch has 2 settings one for HIGH cutoff and one for LOW cycle on. 1/2 of your pressure switch is not functioning properly. With the proper model number I could find a source for the pressure switch for you. There are a couple of different types of presure switchs, One is a stand alone switch on the air plumbing with no external controls (under $30.00) and one is an all-in-one switch that has the on off switch and air lines connected to it that runs around $86.00. You need a pressure switch.... it is just a matter of finding out which one fits your model and replacing it.
Thanks for choosing FixYa,

I have a husky air compressor model WL651004AJ will only build up to 50 psi and compressor keeps running any advise som one could give me to whats wrong.

You can inspect the check valve by removing it and pulling on the small plastic pin sticking out of the middle of the tank side. It should spring back under fairly light tension. Also visually inspect and clean out with a dry q-tip the brass screen on the inlet site. Seal back with ribbon dope.

If this looks ok, remove the 4 bolts holding the head on. Keep all of the sandwiched plates together in order so they go back in easliy. The cylinder sleeve will come off with this stack. Look at the plastic surround on the piston and the inside of the cylinder. In my case, this was eaten up from too many hot summers and cold winters in the garage. The rubber/plastic had hardened and eaten part of itself away. To replace the entire piston assembly on the WL651004AJ, you'll need to get part number WL211000AJ, which in some books is superseded by WL211000SJ.
If the cylinder is scored (meaning that by scraping your fingernail against the lines in it, you catch the nail) then you're probably better off replacing the whole cylinder unit.

I need a new belt for my Husky air compressor but I don't know

This is a simple way to replace your belt without the old one for comparison. Use a piece of rope thick enough to fit inside the pulley, (cloths line works well). Simple wind it around the pulleys marking where the two ends meet. Cut and measure it. Take the piece of rope and measurement to a auto parts store and ask them to match it up. An automotive belt will work fine.
If this is a flat belt they should still be able to help you.
