Atwood Fault Light
*2004 Atwood went to a common DC control Logic
If GAS fails to ignite and PROVE it lit.....
3 attempts then 'lock-out ' and Fault Light comes on
Visual indication of failure
IF the ECO opens whether on GAS or ELECTRIC the Fault Light will come on
ECO opens at 180*F (t-stat failed to open at 140*F)....shuts down all heating sources, 'locks-out' and triggers Fault Light
*Even when on Electric there is a millivolt current to/thru ECO to gas valve to ground so that ECO is included in the temp control loop
**On GAS 12VDC to/thru ECO to gas valve so it drops DC to gas valve
To reset Fault Light/Lock-out condition
Turn On/Off Switch OFF, wait 30 seconds, turn back ON
**IF ECO has opened.....need to correct T-stat issue before using WH again
Suburban Fault Light...
Comes ON when you first turn GAS switch ON....then goes out when Gas ignites and PROVES it lit
Comes back on if Flame fails before t-stat opens
Gas on......Electric completely separte controls and has no Fault Light
