Regulator on my DeWalt D55146 is stuck and the compressor will turn on but it won’t build any air pressure at all?

My dewalt 200psi d55146 will turn on but it won’t build any air pressure and my regulator is stuck, won’t move.

2 Separate Issues – Pumping & Regulating

by: Bill

It’s two separate issues, I’m afraid, Damien.

Even if the regulator is totally pooched, the compressor should pump the tank pressure up to the normal cut out.

That you are not building air in the tank needs to be addressed before the regulator issue, I suspect.

There are many reasons why an air compressor can run but not build pressure. I’ve written about them on pages linked from the Troubleshooting page.

After that issue is resolved, if you still need help with the regulator, please comment.

What’s wrong with my air compressor, it holds air in tank but does not have any pressure

Clogged outlet line or your regulator is broken or turned all the way down to off.
Depending on model, the regulator may have to be replaced.
