55146 dewalt blows safety valve

I have a 55146 air compressor, its a 55146 type 5.


I replaced the manifold and pressure switch.

It builds up pressure like normal and it cuts off and on but still blows the safety valve after it reaches 200 psi which is normal cut out. It blows about 30 seconds later, but builds up and cuts off and on like normal but still blows the safety valve.

You don't say how old it is, but if it's under warranty, ask them to send you new valve, explaing as you did here.

Otherwise, you can try cleaning it. Take a look:

If that doesn't work, buy a new one - probably rated at 220 or so PSI as marked on the one in there now.
