Increase the tension on the air pressure switch spring. It will be the item that usually sits by iteslf on the compressor and has the wire from the motor and wire from the mains power coming into it. The adjustment may or may not be visible with cover in place.

You will see the nut with a washer and spring beneath it. You may or may not need to hold the shaft the nut is when you turn the nut clockwise. It depends on brand of switch. Use insulated tools and use care. Do not force anything because the switch itself may be at fault- if nut is threaded to end of threads on shaft already so you would need an extra deep scket to reach the the nut, the switch may need replacement. Drain tank and leave open if switch replacement is needed.

SOURCE: Pressure won't build up in tank

Your compressor is the oilless type that incorporates a vinyl/teflon piston ring and a cylinder that is open from the bottom. Remove the cover and push the piston to upmost position. Look for scratches along the upper portion of cylinder. If scratched, compression is leaking thru ring and will not fill tank. Replace with Sears part #k0650 cylinder /piston ring kit to restore full power. While the compressor is apart examing the valve plate and reed valves for wear. If worn replace with part #z-ac-0032. Reed valves tend to crack or loose their shape reducing efficiency. If cylinder and ring are in fair condition, then most likely reed/valve plate is the problem. Good luck and email if you have more questions.

SOURCE: 25 gallon air compressor wont shut off,changed air regulator

You have a valve plate problem . It could be a slipped "o" ring to a bad reed valve. There are rebuild kits for that purpose. The kits include a valve plate assembly. It covers all the bases. When you look at this area pay attention to the partitions of the head gasket/"o"ring. You may avoid the cost of the kit.

SOURCE: 6 gallon proforce air compressor not building any pressure

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

SOURCE: craftsman 1 gallon direct drive oil filled wont build air pressure

It sounds like you may have a broken reed on the diaphragm plate. This is located at the block. Remove the cover, and look for a cast metal assembly with fins. It will be attached to the side.

I had the same problem. I tore the compressor motor down, and it was a blown head gasket. Easy fix!

Why will my bostitch pancake compressor 240 psi tank 180 regulator that the guages will not show building pressure


Hi, There are different posibilities. I would need more information. Was it always like that? Does the guage on the main tank and the guage on the regulator both not show more than 20psi? When the auto shut-off is triggered do you feel there is more than 20 psi in the tank?

Why wont my steelcraft 13 gallon 5hp model ta25 build up no more then 20 pound of pressure and all i did was change the oil?


Check all connections for air leak including the water drain valve with soapy water. If no air leaking from connections, spray soapy water on head area where head attaches to the cylinder checking for gasket leaks. If no leaks are found, most likely problem is in the head /valves /internal gasket leak. If head gasket or valves are leaking, you will notice that air seems to blow out of the intake filter (normally there is good suction at the intake). Good luck

AIR PRESSURE PROBLEM


The issue suggests that the head gasket is blown between the two cylinders or the reed valves are not seating or broken. The only other condition that would cause this is a leak. Here are a couple of simple tests. For leak spray soapy water on all connections and fittngs including the pressure regulator and the bottom of the pressure switch while unit is running. Repair as needed. If no leak is found, run compressor untill it reaches 60 or stops increasing and feel for suction at the air filter intake. The best way to check for suction is to remove the air filter and feel for suction at intake port-hole. The suction should be very strong. When valves are leaking it almost feels that the air is blowing out thru intake. If little or no suction, remove head and valveplate and replace parts as needed. Parts are available at www.chpower.com or www.toolpartsdirect.com. Good luck and post again if you have other question.
