Compressor runs hot and won't build pressure

Check Valve in the tank or the reed
valves in the head need to be turned
around or replaced

Clean or replace your check valves.

Turn the pressure adjustment knob in to get the desired pressure.

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.

Hi, my name is John. Welcome to FixYa. check all your air lines for leaks, check the valve at the bottom of tank, check the line coming form the pump to the tank. You may have to remove it to inspect it. I find this one always is over looked. Thanks for choosing FixYa...John

when i turn it on motor runs but it will not build up air pressure

Is there an option for you to run this compressor on 220 volts vs 110 volts??? If so, you may want to convert it by following the re-wire instructions on the motor or wire access plate/instuction book. The reason your compressor won't fire up again after building pressure is the head pressure is to great at restart and 110 household current is not enough to give the power needed to turn the piston. You'll need to replace the plug and have someone run a 220 volt circuit once the conversion is completed.

sounds like valves in head have failed and need to be replaced, that is where I would start looking first.

Needs pressure switch adjusted or new

bad or broken valves
