If you still have the Cedar Back rig then it's a Suburban Water Heater
Both Gas and electric not working is strange cause they have/use separate controls
that are independent of each other
Except for the Suburban 'DEL' model.
It uses DC To control BOTH (similar to Atwood style)
DC Voltage goes to BOTH electric and propane ON/OFF Switches (Inside RV)
After that both operate independently
SO only common component is the DC Feeder Fuse for DC to ON/OFF Switches
If an Atwood Water Heater...
Check the 'thermal fuse' (one shot fuse in clear tubing connected between circuit board and t-stat ---Brown Wire)
If it blows all DC from circuit board is tripped (190*F....blow back from combustion chamber ---dirty/obstructed)
OR DC Feeder Fuse is blown to ON/OFF Switches
Just guessing cause info is very lacking any detail
