2017 DX3 Rear AC E4 Code

2017 Dynamax DX3 rear AC throwing E4 code and blowing hotter air. From what I have read it sounds like a problem with loss of freon. We've had issues with this rear AC making funny sounds for the last couple of years and I think it finally went out. The question is what is a good replacement for this AC? Is the Dometic Atwood 15033 the direct replacement? Also see a lot of subpar reviews on those units. Can someone steer me in the right direction?

I replace mine a couple of year ago. It an easy job, the toughest part was getting it up on the roof. U can find them online.
