We have a 2005 Fleetwood Terra 26 Q and are starting figure everything out. We have the fridge running. Getting ready to put water in. Discovered a red switch on the front of the cabinet beside the range. Does not appear to have anything to do with the range. The burners light. Wondering if anyone has any ideas? It does not light up it just has a red metal case. the part you flip is black, like a light switch. Can't find anything in the books about it. Cruised youtube looking at videos of interiors and haven't seen one with a switch like that.
