Re: Hot water heater too hot
Just electric.. Correct...... ECO terminals are larger then T-stat terminals so BROWN wires will not FIT on ECO\Atwood only uses 140*F t-stat When you pulled the RED wire off ECO were you just heating with electric, with propane or both? From your description sounds like 'power track' on circuit board is shorted NO ECO (RED WIRE removed)...NO Heating electric OR propane unless circuit board is bad558Views0likes0CommentsRe: Hot water heater too hot
I replaced one at a time to avoid confusion, but I believe the wire posts are different sizes and wouldn’t allow for this? dougrainer wrote: 1. Air pocket has no bearing on hot water 2. The standard tstat is either 130 or 140, depends on the year of the Atwood. EITHER tstat, you could NOT just shower on HOT only. You would be scalded. That points to a problem prior to this problem 3. Let it continue the heat cycle and see if the ECO trips and/or the pop off valve opens. No harm if it does 4. It is very easy to install a ECO in place of the tstat. That means the temp of the water could reach 180(ECO Temp trip). I would suspect you have installed the ECO instead of the correct tstat in the tstat mount. Doug559Views0likes0CommentsRe: Hot water heater too hot
GC6a-10E.. Swapped both the t-stat and eco sensors. Removing ECO wire did not turn on any lights, and I could still hear the high pitched sound of the heater active. Removing t-stat wire did not turn on any lights, but did stop the high pitched sound. No light comes on to indicate demand either? Old-Biscuit wrote: Atwood 6 gal...............?????

I was getting too much hot water in comparison to last season. I’ve changed the thermostats, and made sure the air pocket was replaced. Still heating too hot. I used to shower with only the hot water on.. now I have the cold water on full at the same time.. Could things still work to this level but still have a bad circuit board? The two lights on it arent lighting while in demand..2KViews0likes16Comments
