Compressor Will Not Build PressureA compressor is a pump. When that pump is being driven by the electric motor, it pulls in free air from the atmosphere and drives it into the tank. Different styles of air compressors do this in different ways, yet they pretty much all do the same thing.When your compressor is running and the pressure in the tank isn't rising, this is pretty aggravating. What the heck is wrong when the compressor pressure will not build? On this page immediately below is a form that you can use to ask a question about what to do when your compressor will not build pressure? To see existing comments and questions already posted about this subject please scroll to the bottom of this page (below the form). I've just added a page that summarizes many of the answers about why a compressor won't build pressure. That page is right here. Here is another new page that addresses the reed valve issue, to help you better understand how compressor reed valves contribute to why compressors don't build air pressure. If these new pages or the comments at the bottom of this page don't provide the answer for you, just fill in the form and we'll see if we can help. And, if you've got a suggestion about solving the "compressor will not build pressure" problem, also please use the form to let us all know about it, and perhaps help someone else. Thanks.
