What is the model number of your water heater?
If it is an Atwood......'GC' in model means it is 'combo' unit and uses a 110V AC electric element and a propane burner. Either one or both can be used to heat water
Atwood electric would have it's on ON/OFF switch on a dual panel
If it is a Suburban.....'E' at end means it is 'combo' unit.
Suburban electric On/OFF switch is in outside compartment in corner.
Water heater MUST have water in it before turning electric ON.otherwise element will burn out.
Electric will only work when connected to shore power source and turned ON.
Other than having hot water in 20 mins there is no indication of electric working.
Propane you will know when you turn it ON....click/click of ignitor and whoop of main flame lighting off.
Both electric and propane are controlled by thermostats. A normal (preset for 140*F) and a high temp (preset for 180*F)
SO which do you have?
Atwood
