model 921153100 air compressor.does not build up any pressure.


Thank you for your question on the air compressor not pumping up to the target pressure and shutting off.

I would suggest that you start the compressor and put you hand near or on the air intake manifold to see if you can feel any air coming out of the air intake. If you do then the reed valves on the inside of the head are leaking back and it will never reach pressure.

If you find that to be the case then the head of the compressor will have to be removed and the reed valves or reed plate will need to be replaced.

Please let me know what you discover with that test and we can continue to troubleshoot if that is not the problem.
