Atwood water heater reset switch?

[emiddleb]

Ok, I feel dumb, but need some help.

I have an Atwood water heater, model GCH10A-4E (10 gal, gas/electric) probably 2004 vintage (original with RV.)

Works fine on propane, won't heat on electric. Wall Red switch lights but water stays cold.

I've read that there is a reset switch for the electric side which will pop if too hot with no water in tank. I've been all over the heater, including the back side removing the cover where the electric element is located, but cannot locate the button or anything that looks like one.

I know it's possible the heating element has failed and I'll have to replace it, but wanted to try to find this switch first. Probably will get out the multimeter and check power etc but wanted to start with the simplest things first. Have checked 120v breakers etc.

Do only certain models/years have the ECO switch? Am I looking in the wrong spot? Or is it just too small/subtle that I'm missing it?

Thanks for any advice...

Prior to 2004 Atwood used separate set of t-stats for electric and for propane. Electric set was on backside with element
Electric was direct 120V AC and propane used 12V DC to a small circuit board.
In 2004 they used a DC circuit board to operate/control electric and propane. Allowed for just one set of t-stats in outside compartment.

Under the cover for element is a 'relay'.. DC power that allows 120V AC power to element.

Thanks Old-Biscuit. I did get back under there and couldn't find any reset, though I did find the element and various blocks. So new element it is.

There is no 'reset' on your model

The RED Light is a fault light

Propane/electric use same set of t-stats (ECO/T-stat under foam cover in outside compartment)

Your electric element is probably burnt up
