Atwood 'FAULT' Light
If propane fails to ingnite and prove it lit......FAULT light
IF the ECO opens (180*F) when on either propane OR Electric ----FAULT light
ECO opens when t-stat (140*F) fails to open and control heating cycles.
When on Electric the ECO is placed in the circuit via a millivolt signal -----this way the ECO can function on High Temp and gas valve does not get enough voltage to energize the gas valve solenoids.
ECO needs to be part of control scheme.
High water temps......weeping from T&P Relief Valve.......LOSS of Air Pocket (controls pressure increases from heating water) AND T-stat did not open
Establish air pocket and replace t-stat
