Thanks @okieGene and Sound Guy
I think I knew and forgot that we needed the battery to run the fridge. Thanks for the reminder!!
My cousin, who is an HVAC guy and also knows quite a bit about absorption refers, is camping with us next week! I talked to him and he will bring tools and help us accurately diagnose the problem. But, for sure I want that on/off switch for the Climate Control. Is that a special switch or can we purchase at any electric supply? And how was it fastened to side of refer?
Meanwhile, we're still poking around a bit. Learning as much about the refer as we can.
We have an appointment with our RV guys on August 3rd. If all else fails, we'll take it in.
