There are a number of different controls for Atwood heaters. The panel is, shall we say, optional.
If you have two switches, one for gas, one for electric, and a light... Well let me describe my system
Two switches internal lights, plus a FAULT light. as someone above said the fault light only comes on if something goes wrong.. ON PROPANE this would normally be failure to light.. On both propane and electric if the ECO (Emergency Cut Off Thermostat) opens, it will set the fault light. IF you follow the factory suggested winterizing process (Which includes removal of the red wire from the ECO) and fail to re-attrach the wire.. FAULT LIGHT, If you have to ask how I know this.... You likely are unable to read this post :) ).
As for the lights inside the switches.. Yes, those like to burn out.
A electronics store (The kind of store where Joe's TV shops for parts) I freqauent sells a plastic tube, roughly a qauarter inch in diamater and perhaps 2 inches long. One end has a plastic lense, and a ring (Retainer ring or collar) the other end wires,, They also sell a bit of spring steels that slips over the tube (Speed nut).
They sell several versions of these, one is marked 120 volt (Wires are both same color) the rest are marked 12 volt (Differnet color lenses and one wire is red, other wire may be black or white, does not matter which)
I drill a hole near the switch, insert tube, slip nut over wires and tube and connect leads to switch.. Switch (lighted) has 3 terminals, one is ground one is 12 volt hot one switched. The light itself figures out which, RED is positive switched.
NOTE: if your panel does not have lighted switches, and you would like to add this feature... The same method works.. The only thing you will have to do is find a ground lead,, Hook the non-red wire to the ground switch.
now with the water heater switch OFF touch the red lead to one terminal, if it lights, hook it to the OTHER terminal, if it does not light, hook it to that terminal and try the switch, Should light when switch on.
