No pressure build up in Task Force Model No. 83691

Task Force Model No. 83691, 2 gallons, 100 psi max.


Regulator turned to max, drain valve closed, no leaks detected, no pressure build up. Could the regulator be bad? What other bad parts could cause this?

Hello Don, nice to hear from you, and sorry you're having trouble with your air compressor.

No, it won't be a regulator problem. A regulator is used to set the pressure of the compressed air to your desired setting when it is being used.

The regulator is on the tank discharge line, and has nothing to do with compressing the air.

If the motor is running, if the motor shaft is turning and is connected properly to the compressor piston assembly, if the piston seals are not worn to the point that the air is blowing by them, and if the intake valve is working properly, then you should be compressing air.

There will be an air intake filter near the top of your compressor head. Take the filter off and run the compressor. Air should be being sucked into that small opening, and no air should be coming back out. Is there?

If there is, it would suggest that the intake valve has failed, and now all your compressor is doing is pulling air into the cylinder on the piston retract, and then blowing that same air back out the intake hole on the compression stroke.

Air flows to the path of least resistance, and if the intake valve has failed, the path of least resistance will be right back out the same hole the air came in through.

Check that out, and then let us know the results, please.

Cheers,

Bill

MY 83691 STOPPED RUNNING
by: JOE P.

THIS LITTLE COMPRESSOR IS ABOUT 3 YEARS OLD.
LATELY IT TOOK A VERY LONG TIME TO BUILD UP ENOUGH PRESSURE.. AND THEN THE PRESSURE DISSIPATED VERY QUICKLY AS SOON AS IT WAS TURNED ON. LAST WEEK I FORGOT TO TURN THE BLOWER
OFF FOR ABOUT 4 DAYS. WHEN I WENT TO USE IT, THE BLOWER WAS STILL RUNNING, BUT THE MOTOR WILL NOT TURN ON AND THERE WAS NO AIR LEFT IN THE TANK.
I ALWAYS DRAINED THE VALVE... AS PER INSTRUCTIONS.DO YOU THINK IT COULD BE REPAIRED OR
I SHOULD FORGET ABOUT IT. COULD THE BRUSHES HAVE ANYTHING TO DO WITH THE PROBLEM?.
IF THIS LITTLE MACHINE COULD BE FIXED, WHERE SHOULD I TAKE IT?. THANK YOU
JOE






Bill wonders...

First off, welcome Joe. Thanks for visiting and writing in.

What blower? I regret that I have no idea what you are talking about when you say the blower was running for days.

As to the compressor starting (or in your case not starting) go to the Troubleshooting page and click on the "Will Not Start" link on that page, and then read the questions and answers. I think you'll find most of what you want there.

As to repairing, if you purchased the unit yourself, ask the store where they get their compressors fixed under warranty and go there.

Otherwise, go to the Repairs page and see if there is a repair depot near you.

Cheers,

Bill

Task force air compressor Model No. 83691

Hi and thanks,

My air compressor (that I inherited and don't know the history) just won't turn on. I changed the fuse and checked all the wire connections, and I cant figure it out.

It just seems dead... Do you have any suggestion? There's definitely power going to the unit (I know because I shocked myself like and idiot).

I'm all out of ideas.

Thanks,

What, on your air compressor, that allows power to flow from the power supply to the motor, is the pressure switch.

When the pressure in the tank is below the switch "switching" cut in pressure, the switch closes and allows power to flow to, and hopefully start, the compressor motor.

You say you know you have power to the compressor, but do you have power going through the switch, assuming that the pressure in the tank is below the cut in pressure setting?

Please check that out (carefully ;-) and post back here if that is or isn't the case.

Cheers,

Bill
