Sorry 'jdavis1877'........that Model is GAS only with Pilot Flame
Possibly previous owner had issues with original water heater which could have been a Electric/Propane ......replaced it with just a gas only
Otherwise NO reason for RV MFG to install/designate a AC Circuit Breaker for 'H. Water"
Do you have the original component list....inside a cabinet door or drawer etc
It would list OEM equipment trailer came with
Is it time for your medication or mine?
