Atwood water heater question.

Check the water temperature when you think the water is hot enough and the unit should shut down. The thermostat will control the temperature at around 140F or so. If the thermostat fails, the ECO will shut the unit down at about 180F. Should that happen, you will have to turn the unit off and then back on to get it to light again. The thermostat and ECO are sold as a pair and it takes only about 5 minutes to replace them.

My t-stat failed and I had extremely hot water. I checked the temperature and it was about 170F. Way to hot for safety.

Of course, this may not be your problem but checking the temp will tell you if the heater has reached the temperature for the t-stat to shut the burner down.

Go here for a service manual. Bryant RV . The water heater manual is near the bottom of the page

I'm going to get a thermostat and ECO kit tomorrow. Hope the rv place hs it in stock!
I'll keep you posted

My light will still stay on even after it heats the water up to it's set point, and then it will cycle on and off as needed until I flick the switch off.
I would think that if it kept the flame going, it would eventually blow the safety valve

It's still flaming until I flick the switch. I haven't let it go long enough for the PRV to pop.
I think the longest it was on for was 40 min max

Is this when operating on LP mode or Electric mode?
