Heartland Cyclone Water Heater

[mcnamarac]

Need some help! We are living full time in our fifth wheel, and I am unable to get the water heater working. I’m wondering if it a bad control board within the water heater, because on multiplied meter tool I  have no voltage reading to the brown wire when the switch is on inside the RV on our main control panel. All circuits are on in the main circuit breaker, and as far as the fuses, there are none labeled as Water Heater. 

My fifth wheel is a 2016 Heartland Cyclone 4100. Water heater is Atwood. Any help would be amazing! My wife and kids are tired of cold showers.

Here's a link to the manual I'm looking at.

Thanks for that information. That is super helpful. I reckon tomorrow I will dive a bit deeper into it and see what I can’t figure out. That manual you found is a game changer thank you for that! 

Fun times over here haha

Based on your picture with a brown wire at each end of the board it looks like:

When on Electric you should see 12 v between the white wire (+) and the green wire (-) at the plug.
When on Gas you should see 12 v between the orange wire (+) and the green wire (-) at the plug

Of course I'm guessing at the model so the wire colors might be different.

Unfortunately we really need a model number on that heater if possible. For instance in the 6 gallon models there is a wire color difference between a G6A-3E and a G6A-7E.

Aside from that I would use a small flat blade screwdriver and pop the switch out of the wall panel. Check that 12 volts is getting to the switch and if it's getting through the switch to the downstream side.

Are you trying to operate it on gas or 120V? Because if you are fulltiming and plugged in you should be operating on 120V and the wires to check for voltage are black and white (not brown). If you are trying to operate on gas then the trouble shooting is a whole different ballgame (I.e.: good battery, good converter, 120V power, fuses at converter, gas source, etc.)

Thanks for that! Yeah I’m plugged in shore power. Here’s what I’m working with. I’m not getting any voltage off the brown wire, which form other videos is the power wire for these from the main control panel inside the rv at the little red switches for water heater

On my water heater, the ON/OFF switch on the heater itself keeps melting. Right now we're running propane only.
