Sears PartsDirect has the Craftsman 60-gallon air compressor parts you need to keep your pneumatic tools running smoothly ![]() If the compressor won't start with air in the tank, replace the check valve. Bleed air out of the tank to reach the cut-in pressure so the pressure switch attempts to restart the motor to refill the air tank. Turn on the compressor to fill the air tank. Test the check valve by shutting off the compressor and pulling the ring on the safety valve to bleed the air from the air tank until it's empty. The stuck-open check valve causes high pump head pressure, preventing the compressor from restarting. The check valve prevents tank air from back flowing to the pump. If the compressor won't restart after it fills the air tank, the check valve is likely stuck open. What to do when your Craftsman air compressor when it won't start with a full air tank The valve plate regulates airflow into and out of the pump cylinder to compress air, so replace the valve plate if damaged.If the pump won't compress air, rebuild the air compressor pump. Worn pump seals prevent the pump from compressing air.Replace the safety valve if it leaks air constantly. The safety valve pops open to relieve excessive air pressure if the pressure switch fails to shut off the air compressor at the cut-out pressure setting.Tighten loose air tube fittings to prevent air leaks.Check for air tank leaks and replace the tank if it's leaking.Shut the drain valve at the bottom of the tank if it's open. ![]() If there is still leakage, you may need to replace the manifold.How to fix your Craftsman air compressor when it won't build tank pressure First, check that all of the connections are securely fastened. There are many potential issues here in terms of air leakage. Manifold kit-The manifold kit is the combination of your pressure gauge, connection to the tank and hose couplings.If your tank air supply is over-pressurizing tools, take a moment to check whether the pressure regulator is stuck. ![]() Pressure regulator-The pressure regulator is controlled by adjusting a handle to set tank outlet air pressure.If you check your compressor and there are no air leaks, but the tool has low air pressure or power, then the air compression may be restricted by a faulty valve plate. Excess wear on the compressor valve plate can cause air flow problems in the pump. Valve plate assembly-The valve plate controls airflow through the pump of an air compressor.Replace the intake filter if it’s damaged or it isn’t muffling compressor noise. Intake filter kit-The intake filter kit helps your compressor operate quietly and efficiently.If you notice your compressor is constantly kicking on and there is no air hose leak or air hiss, check under the manifold for air leakage. The main issue with air compressors is that they leak air and are constantly having to build pressure back up. Head gasket-The head gasket seals the pump assembly and allows for proper compression of the cylinder(s).Five air compressor parts that might break
