Hey Robert, thanks for all of the info you mentioned. Basically you have an air leak in your setup and that is causing your compressor to run and run and eventually it shuts down as it can sense there's a leak and there's no reason to keep trying.

You will have to find the leak. Easy way is to put soapy water into a spray bottle and spray the bags and the lines until you see bubbles indicating that's where the leak is and fix as needed. Let me know what you find and if you get stuck and I'll see what else you can do.

Okay, I have already done that and I can’t find any leaks I pull the one and only hose connected to the compressor and no air is coming from that port while the compressor is on.

@RobertL Do you have a manual inflation valve you could use too? I would try inflating the bags with that and then testing with an air pressure gauge to see if it's holding pressure. You can also put the gauge on the valve while the compressor is running to see if any pressure changes occur. It's possible the compressor just isn't pushing any air and its just "running" for 4 minutes and then throwing an error code.

@JamesonC Hello, okay I bought a replacement compressor and that fixed my issue now they have been working for several months since I got them fixed and now I have a ECN code I have seen it means it lost communication with the compressor but how do I know what part is the problem?
