Atwood Hot Water Heater Trouble Shooting
Just got a used tt with an Atwood Hot Water Heater, works both on propane and shore electric. Unoit works well on gas, but I cannot get it to work on 110v AC. The Atwood literature that came with the trailer seems to be no help. Can anyone direct me to a trouble shooting tree? Thanks

Check for circuit breaker being tripped and make sure that you have water in the heater before turning electric on or it will blow the heating element out... Jim

A lot of TT's don't have water heaters with the 120 volt heating element. Are you sure yours has one? If it does then you need to check the heating element as they can burn out if turned on with no water in the unit.

Next time I pick up my TT I will take a picture of the schematic (it's a 10gal unit in a 2005 not sure of model off hand). I had to replace my heater element due to turning on electric without water in it, was only on for about a min but that's all it takes.

Basically follow the line of wiring, and see were you lose power.
Which model number WH is it and does the control board have one or two wiring harness plugs at it?
Some only have 120V switches, some use 12V to close a relay to engage the 120V element.
But start at the breaker, see if you have a switch on a cabinet or wall, test it. Switch at the WH, test it. Could be a t-stat and eco just for 120V. Then the element itself.

I have had lots of different issues. My first thought after reading your quote is that there is a reset button on the back of (my) the tank. It was very hard to find as it was indented. You have to use a pencil eraser (or some thing like that) to push it in which resets the 110 side of the heater. You might have to pull the heater out of its location to get at the back. I would get proper documentation before doing so. Good luck hope that helps
