Question about Craftsman 3 gal. Air Compressor, 1.5 hp, Horizontal k
When i switch the compressor on it runs good till it reaches 40 psi and then pressure never increases after that. It just keeps running.
When I turn compressor on it does not build up any pressure ?

I had mine do the same thing... The head gasket blew out between the intake & discharge side.
I went to O'rileys and bought the blue gasket paper and cut out a new one ($3.00) works fine now.
Just take off the plastic cover, undo the discharge line at the compressor head, remove 4 allen
head bolts, lift off cylinder head and you'll see the gasket gone at the center bridge.
Draw a picture of the way the valve plate under the head is assembled so it goes back together right.
Use care cleaning the old gasket off, NO power tools....Hand wire brush to preserve the little ridges
that bite into the gasket, Soak with solvent helps..You can also order the gasket kit from Sears
about $12.00...Hope this helps ya......John

Are you talking about removing the small plastic cover where the on/off switch is or the large plastic shroud? I am having trouble getting the small allen head screws to come out. what's the trick?
