Water heater not working

I just bought a 2000 Airstream Land Yacht and the water heater isn't working. The light doesn't go on when I turn the switch on. The fuse in the panel is good. The switch on the unit is on. There is water in the unit, valves open, etc. Shouldn't the light at the switch go on even if the mother board was bad, or there was some other problem at the water heater?

    Sounds like a Suburban with the outside on/off switch , which for 120v, nothing to do with the inside on/off that goes with the red light, which is for gas mode. Should be a 120v switch inside for 120v mode.

    If so, first hit the reset buttons outside under the black rubber cover and try again. (one for each tstat) See if it works on 120 but not on gas or VV. Either way it needs 12v to operate the controls.

    Whatever, do report the exact model of the WH so the experts here can provide some actual help.

    It's an Atwood. I'll check the number tomorrow. My question is should the indicator light next to the switch light up when the switch is turned on regardless of problems downstream at the unit itself? Since it doesn't might that indicate the switch is faulty, or isn't receiving power?

    No ignition. Plenty of propane. It's as if the switch itself is bad, though that may not be the case, but if the switch was bad the symptoms would be the same.

    Sorry. It's an Atwood. I'm using it with LP.


    LP only model or LP/Electric?
