Are the new pancake compressors supposed to continuously run !!


Bought a sanborn and it wouldn't shut off when it reached pressure so took it back and got a
bought a bostitch and the same thing what am I missing !!

Hi Ridgway.

Since you still have the Bostitch, what is happening to the air pressure in the tank? Is it still building past the normal cut out pressure level...?

Let me know as a comment here, please.

Thanks,

Bill

Bostitch Pancake keeps running.........
by: R White

Same problem here... builds to the desired pressure (100 psi) and then the motor sounds like it is running faster and has a slightly higher pitch. Keeps running until I switch it off and then I turn it back on and it does not continue running. Occasionally, it shuts itself off and runs great.
What's up with that? Fix?
____________________
When the pressure in the tank reaches the normal cut out, the pressure switch should trip to non-passing, and power to the motor should stop.

Use a multi-meter (carefully) to check the power on the motor side of the switch. If, when the pressure reaches cut out, that power stays on, that suggests that your pressure switch is the problem.

Greetings.

I sure wish I knew if you had had a chance to look at the reed valve pages and general reasons pages linked from the Compressor Will Not Build Pressure page. You haven't provided me any real info to work with.

There are a number of things you could check right away noted on those pages. Air coming out of the intake port, for example, is a symptom of valve failure, and that could account for why your air compressor won't build pressure past 25 PSI.

Give me some idea what you've looked at please, and then we can work some more towards figuring out what's happening on your compressor.

Cheers,

Bill

bostitch pancake 6g ol 195 will not restart

compressor came unpluged while running now it wont start how do I get it started again

John, what is the pressure in the tank? If the pressure in the tank is above cut out, then the compressor will not start until the tank pressure falls to the cut in level.

Please open the tank drain and let the pressure fall to zero. Try to start the compressor again. Do you hear or see anything happening on the compressor?

Running and then stopped?

by Stephen

Bostich CAP60P-OF ... the compressor was running and then stopped... wont build up pressure.

After that it wont build up pressure. it seems to run fine so i took it apart and all of the componets seem fine, the seals look good. so im wondering what else would cause this problem.

Stephen, the usual culprit for an air compressor that runs and does not build pressure is the intake or pressure valve, or an internal gasket that lets go under pressure.

See the compressor TROUBLESHOOTING page, and click the link to "will not build pressure" for more info.

Past a comment here with more information about your developments on troubleshooting your air compressor.

Bill

My 6 gallon pancake Bostitch compressor took 14 minutes to build up to 140 psi and keeps running and will not shut off. Any idea what's wrong? Thanks so much!
