2001 Ultra Supreme Class A

[jddangelo]

Hi all, we have an 01 Ultra Supreme Class A and under the kitchen sink we have 2 switches. One switch is a 3way with the bedroom for the aisle lighting and the other one is unknown. I have checked many items including hwt, outside lights and many more. If anyone here has the same switches please let us know what the second switch controls. Also the second switch is labeled on/off and the aisle one is not

Thanks in advance

It sounds like this would be a switch for the electric mode (120 vac) operation for the water heater. Mine is located at the end of the kitchen cabinet and controls the receptacle the water heater cord is plugged into.

Thanks I figured out the switch this afternoon. The previous owner or Gulfstream had miswired the switch. It is to control the four ceiling lights and is now working properly.
