New bostitch pancake doesn’t shut off when it reaches pressure. 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 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 and then we can pursue the reason.
Bostitch running and then stopped?

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.
Post a comment here with more information about what you found when you did the checks, please.
Bostitch taking a long time to fill

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!

What was the fill time when it was working properly, please?
Rather than retype all of the issues that could cause this compressor problem here, they are found, in detail, in the compressor troubleshooting section on this site. Please see the pages that refer to info about why air compressors run long, but don’t build pressure.
Had a look? When you check out your compressor using those pages as a guide, what did you find? Please add a comment.
One last trick was I plugged the safety release valve and as it turns out, the pressure sensor was working fine, but the pressure safety valve was blowing just before the sensor would have shut off the compressor. I’ve ordered a replacement valve and that should be that! Thanks to you for holding this forum!
I have a Bostitch Cap1512-OF and the compressor continues to build pressure til the relief valve blows. I’ve replaced the pressure sensor with a new one and cleaned the connectors and same problem. What next? Any way to dial down the pressure sensor? Thanks
I have a 1yr old bostitch air compressor it will build initial pressure then stop but will let the tank run to empty and not build up pressure. I have to unplug and restart, then it will again fill the tank and stop. do i need a new pressure valve?
