My brotherNlaw has a 110v air compressor he bought 18 years ago and last week it failed. Every few weeks we visit their house and he showed me the compressor taken apart.
Frankly it took me several minutes since it was only the second one I've worked on.
I noticed the open hole in the head of the compressor had no plug or valve to compress the incoming air.
He is 76 and has just recently wanted to fix things around the house. So far lawn mowers transmission, pressure washer carb, and now his air compressor.
I have been a tinkerer all my life and as a child destroyed several things by taking thing apart just to see how they work, but my father got made at me for trying. My brotherNlaw just got the bug last year at 75.
I convince him to take it further apart before he tossed it, and he found the problem. A plastic flat that covered the compression hole has slid over out of view. He squeezed it back after we left and he called me hollowing, "It works!."
My nephew in Lake Charles La, favorite show is , "How's it Made." He is 8 years old.
If you think you can fix it, get into it, take it apart first before you toss something.
You find the answer, and it my be better built than anything made today.
