Mystery switch over the 3-way fridge?

Jay_and_Kat

I swear I saw this topic a couple weeks ago, but I can't find it again...

When getting our walkthrough of our new 400, we found a "mystery switch" mounted above the 3-way fridge on the hinge side.  No label to indicate what it might do and the tech giving the walkthrough didn't know.  We tried turning it (presumably) on, which caused a green LED to light on the switch, but nothing else seemed to happen.

So, any ideas what it might be?  We and the tech suspect it MIGHT be related to the solar, but, is it?

Here are the threads....the first few threads should help.

@pthomas745 thank you!  I'm 99% sure the second link in the search is the one I recalled reading!  (I did try the search function here, but didn't find it)

It’s for the auxiliary fan. Recently purchased a 400 and that’s what the PDI inspector introduced it to me as.

It allows the fridge to run from 12V when on.

It's not for the auxiliary fan (it is on the 320 but not the 400) ditto subkron above.

Hey nucamp...kind of crazy to have an unlabeled switch when the function isn't obvious!

This is the part of one of the threads quoted above that goes through the function of the switch.  Yes, it is overly confusing! Find "Bergers" comment.
