Greetings & thanks to this forum for multitudes of info... Trying to get bearings on new 2020 400, any info on this switch that lights up blue next to radio?  Thanks

It is a switch for the fridge fan and reports indicate the switch must be on for the three way fridge to work on 12v.

For both 12v and gas operated. It runs a fan. Not sure if it cools the condenser or the evaporator, but the fridge will not permit itself to run 12v or gas unless it is on.

Email from nuCamp Tech:

"That is the refrigerator fan switch to help circulate hot air made by the refrigerator.  I would recommend running it at all times😊"

Yes, it is not specific to any power source.  But, weird that they didn’t just hardwire a fan to work without that button.  The fan may have been an afterthought.

Mine will run on gas without that switch on.  Only 12V will not run without that switch on.

Ditto. Will not run on 12V without the switch in on position. Good to know they recommend having it on regardless of power source.
