Propane water heater question.

[Steve079]

Seem to have an issue with the water heater switch on our 2019 FF 25rs. It's a dual element; electric element is switched off, but the propane doesn't seem to shut off. The rocker switch is lit (allegedly) when it's on, but even when off, it still cycles. I hear it at night, kicked on twice between 4am and when I got up to go to thru the manuals.Our old Springdale had an on/off and a one for switching between electric and gas..
Also as long as I'm here....When I'm on shore power (first time with full hookups) I don't think I've heard the inverter run for the batteries. Is that normal?

If the water heater still cycles when the rocker switch is in the off (un-lit) position, then it sounds like someone jumped that switch. Check the area behind the control panel -- did someone run a wire between the two wires leading to the switch?

If that's true, that would be very odd, but I can't think of how else the water heater would still fire up with the switch in the off position.

Perhaps there is some confusion RE: the switch being “off vs on” & the red light being “lit vs unlit”? My water heater is propane only so what I’m saying here may not apply but when I put the water heater switch in the on position (after ensuring that the tank is full), the red light in the switch illuminates. Once the water in the tank reaches its preset temp, the light goes off even though the switch is still in the “on” position. The water heater does periodically cycle “on” when the temp drops out of the preset range AND the red light is lit when the burner is active.
I’d consult the (I’m guessing Suburban) User Guide for the dual mode WH specifics. I would think that when the electric mode is off, the WH would function the same as the propane only models. When the electric mode is on, the propane mode should be disabled and the switch by the sink would control whichever mode the WH was in. I can’t really imagine why anyone would bypass the switch! But stranger things are done.

We have a 2017 and our water heater is gas only you might want to make sure yours is both.

Steve, to address the second question, the fan inside the converter is temperature controlled. If your lights and other 12v items work well then your converter may be running cool enough to not need the built in fan.
I'm not able to advise on the water heater.
Our water heater is propane but I added a Hott Rodd kit to it and haven't used propane since.
