Won't cycle on

SOURCE: ec12 hard restart after drop in air pressure

It sounds like the air pressure assembly unit is not reading the pressure drop. some of these units have adjustments under the covers and be reset.

SOURCE: air compressor slow to build air pressure.

you might need to checktosee if the filter is blocked or dirty were the air intake is just like a car dirt can build up there.

SOURCE: air compressor trips breaker after it has built pressure.

you have air leaking back to the cylinder which means when it goes on the compression stroke the air in the tanks have gone in to the cylinder and this makes it hard for the piston to go up on the tank from the pump is a pipe that leads into a gold non return valve this has a rubber ring and a spring inside take this out and turnit over then try this obviously draining the tank if this doesnt help check the oil level and if thats ok your motor must be seizing up on bearings get back to me buddy

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

Here are a few things to check.
You may have already checked some of these.

Electricity...Compressors will run best with full 115Vot 15AMP/Or 220V electrical supply from a circuit, over the shortest electrical cord as possible.

Air Leaks..Place your ear close to the compressor and listen for air leaking, if you hear air that is not normal and means you have to locate and repair whatever it is that is leaking.
Check the air unloader valve... The air unloader valve will blown out air when you turned off the compressor, that is normal.
But it should not have air leaking out of it all of the time. If so then it is faulty and in need of repair/replacement.

Valves...If either the intake or exaust valves fail, breaks, or fails to seat, then your compressor will run 24 hours a day and never build up to the correct pressure for shut-off.

Gaskets...Check to see if your gaskets have failed.
You could have a gasket failure between the pistons and you will never know it because it shows no external air leak.
If this situation happens then the air will only cycle between cylinders and never build up the correct air pressure.
One way to check the gasket is remove the air filter, then put your hand over the intake.
If correct then it will **** you hand against the intake.
If the valve or valves have failed then you will feel the air sucking in and blowing out.

Piston Rings and Cylinder...The piston rings could be stuck,broken, or worn and not allowing the correct pressure to build up in your tank.
A worn cylinder will also contribute to the problem of pressure build-up.
