You have an Atwood water heater which uses 12V DC to control the electric & propane heating
The DC triggers the 120V AC to electric element via a DC Relay
The DC controls ALL functions
12V DC comes from a FUSED source...so you have probably blown a fuse

Could have blown a fuse, bad controller or bad SWITCH

He has a 2004. That puts his water heater in the time where Atwood still had separate controls for 120 and LP. Just because he states he flips the switches up front for LP or 120 does NOT point to a newer all 12 volt control system. A LOT of OEMs ran the 120 wall switch next to the LP On/Off switch. He may have 2 problems. He needs to state Brand and MODEL of his Heater. Doug

OP stated:
No power to water heater (Gas OR Electric)

3E models do use separate controls ---Independent sources of power/t-stats etc
4E models use SAME for both electric/propane

OP's doesn't heat via electric OR propane....suggest Common System (4E)
3E model and BOTH not working......highly unlikely since they are NOT connected or have common controls

I agree. BUT, The OP has NO CLUE. HOW does he determine he has NO power to the Water Heater system????? How does/did he determine he has NO POWER (120) or 12 volt??? THAT is why we need Brand and MODEL number. Without that, everybody is just spinning wheels. Doug
