Air compressor not working

SOURCE: WILL NOT BUILD PRESSURE

Many craftsman compressor are built by champbell hausfeld using a dry type of cylinder and piston (no oil, no crankcase). If dry type, check for worn cylinder and piston ring. Pieces of the vinyl ring can jamb between the reed valves in the head causing air to escape from the intake. If your compressor has a crankcase and oil, check for broken reed valves in head. Spray soap solution on hoses, checkvalve, drainvalve, and fittings to check for leaks. Most likely problem is reed valves broken or open. Parts are available from sears or match parts to chpower.com. enjoy

You might have a broken valve. You'll need to pull the head apart. But make sure replacement parts are available first. Does this unit have an unloader valve on it ? That could also be your problem. You probably should check this first
