Your Atwood model uses one set of t-stat/eco, one control board and same DC Voltage for heating with electric and/or propane.
The 120V AC to electric element is triggered via a DC Relay
White wire to circuit board is the DC from electric on/off switch
Then DC must go to/thru t-stat and back to circuit board
Then a very small millivolt goes to/thru ECO and gas valve so ECO is part of control circuit
THEN DC goes to relay to trigger AC to element
Any loss of DC prior to relay will not allow electric element to function
AC at the DC relay and element can be issue also....there are on backside of tank under the black protective cover......PITA to access
SO check DC circuit first
Here is the wiring scheme
