Flame not relighting when t-stat calls for heat (over 6-8 hours it would cycle SEVERAL times) is #1 reason RED Fault Light comes on
If thermostat was going bad it would either NOT heat at all or would overheat
ECO would then trip and lockout water heater (trigger the RED Fault Light)
What year is this water heater?
Sounds like the circuit board is causing problems.....which Atwood boards have an issue with
Good info there. My water heater from 2006 and is a gas only unit. I'll try to post a picture of it. The water heater manual is the only one I don't have from when I bought the trailer new. I'll try to post a picture of it. Thanks.
