I have a campbell hausfeld 2 gallon 135 max psi compressor suddenly stop working, when i turn the switch on, and making sure its plugged into a "hot" outlet, nothing happens, no buzzing, no sound or hissing no nothing...is there an internal fuse blown??

Your problem is most likely because of damage to the valve plate or piston & cylinder. If one or both of these are not working properly you'll get partial pressure and the unit won't turn off because the tank never comes up to full pressure. Things to check for are damage to the reeds on the valve plate, they could be bent from overheating or broken from use or wear or damage to the piston seal which can cause damage to the cylinder. If any of these aren't sealing properly the air pressure will come up to a point where the air leaks out faster than it goes into the tank. Without your particular model number I don't know which parts to recommend but if you contact Campbell Hausfeld they'll help you get the right parts.

take the power surply cover off and look down the side on the butten at the contacts, id say it isnot the pressur switch itself, and make sure all bolts are tight and check the reeds

If I read your problem you would like to decrease your pressure setting on a campbell hausfield compressor, this usually can be done by turning the 3/8" nut (typical) counter clockwise which decreases the spring tension on the pressure plate allowing less pressure to break the points. Hope This Helps Don

the unloader valve is deffective , this has a small metal rod which activates a microswitch to turn the machine off , replace the unloader valve

plz follow this link and choose your model and get the manuals.

i hope u will get the solution.

There should be a reset button on the motor. Try that first. Otherwise, it is a bad pressure switch or internal motor problem. If resetting the motor allows the unit to start, but it just hums, shut it off right away, bleed off all pressure and try again. Let us know what happens.

REPLACE THE PRESSURE SWITCH BUDDY THESE CAN BECOME FAULTY WHICH IS THE CASE OF THIS PROBLEM BUY THEM ON EBAY FOR CHEAP THE PRESSURE SWITCH CONTROLLES YOUR ON AND OFFF AND STOPING PRESSURE SO THAT HAS GOT TO BEE THE PROBLENM OR TRY AND TAP IT A BIT TO MAKE IT WORK

Compressor has a bad valve. Needs to be replaced. The owners manual should have a break down of the compressor. Order the head kit.

Your comperssor is oilless type and suffers from short cylinder / piston life. When the compressor no longer reaches cycle pressure the cylinder / piston should be replaced. These parts are available at www.chpower.com I believe that the part number is wl210300aj. Not expensive, enjoy.
