Ron, it's already been confirmed that switch IS for the electric water heater element. It already been explained not to turn on the element without water in the tank...Seems it's been all explained??? Nope, not yet! Ha Ha Ha, there's more. Just because the red light is on, doesn't mean anything regarding getting hot water!
Word is that the electric must never be turned on with no water in the hot water tank. This empty condition can occur after winterization, with tank on bypass. Of course, to prevent vaporizing your heater element, there is a Suburban-supplied switch behind the external heater access door. This switch has a pin thru the handle to prevent accidently energizing the element with the inside-your-coach unmarked switch. Too bad that apparently our coach manufacturer continues to NOT mark the inside-the-coach switch as to it's function, and continues to provide the indicator lamp that turns on regardless of the state of the all important external switch.
Wouldn't it be nice to:
1) have the switch identified?
2) have the switch indicate that electric power really is applied to the heater element?
I'm thinking maybe GS just wanted to give us something to talk about?
