Re: 2004 yellowstone
Are you sure it's not the water heater? On my unit ther is a switch for electric operation of the water heater as well as LP.
There also is a switch outside on the water heater that has a small safety pin to keep it from operating on electric if the hot water tank is empty, this switch has to be turned on too for electric operation.
The only other thing I can think of is possible heat blankets on your tanks, the switch might turn on the tank heaters. It also could be for some type of night lighting along the floors, you probably would have noticed that, unless the bulbs are burned out.
