Compressor won't build pressure past 50 PSI.

[Sonar Chief]

At first I did the dummy check ... is it really only 50 psi? I use the air hose and point it at your face ... yep 50 psi! Regulator checks sat!

I went ahead and ordered a check valve for the input port just in case, but the way I understand it ... if the check valve was inoperable it would direct the pressure to the relief switch and it would shut down, right??

There is no air that I can feel coming outa the port either .... the saga continues.

Thanks for commenting Greg...

When my check valve went out it let compressed air out to the atmosphere. You could hear it.

Same website - has a check list of things to consider and look for.... seems your issue is very common.

Thanks for the link ... at least I wasn't holding my breath for an answer from Sears!

Thanks again .... reading time now!

Well, this is frustrating as hell! After I replaced the pistons and cylinders, new gasket it would make about 35psi. Hmmm... bought the plates or "heads" which contain the intake and exhaust reeds, replaced them and the gauge, still running forever and never gets past 35psi, what the halibut?

Forums and emails have not helped much as I have replaced everything mechanical, the electric motor is not running hot (as it would if it lost one 120 vac line) ... so?

If anyone needs a 275 paper weight let me know! jk

I still need to get this fixed so I can keep using my air tools!

Any other suggestions?

Thanks again,

Michael

Is the unloader valve stuck partly open?
