Atwood dual water heater switch

I drives me stark raving nuts that the switch does not have a light indicating gas or electric is on. It does have a light between the switches but only comes on when there is a fault with the propane side not working, Could I install a lighted rocker switch in place of the existing rockers. I was thinking red for electric and blue for gas. Any electical gurus out there that could tell me if it would work? Here is a pdf of the heater, scroll down to see the switch schematic.

    Yep, Just hooked it all up. Works as advertised. Easy and great mod. $8 and less than 10 minutes. Was not plugged in and it showed being on when switched to electric and could hear the relay running. Pretty sure when we are boon docking I will know we are not hooked up to shore power.

  • Use a 12 volt led with the exising switch.
    That's what I did with my Atwood. The switches just switch +12 on and off, but to be safe, make sure yours works the same way. The last I checked, the electric switches for the Suburban heaters directly switch the 120 volt AC element power.

    It would be easy- just hook the new 3rd terminal of each switch, the ground for the light, to the existing fault light ground.


    Thanks, I think that is what I was looking for.

  • You can tell if the switches are on by their postion, down is off on mine. Left is electric or eco mode right is gas.
