If the water heater plugs into an outlet, and there is no power to the outlet, then the problem should not be in the water heater. Test outlet with a known good appliance such as a drill motor.
Some water heaters have a switch in the exterior and inside to operate water heater control. The one out side is for protection of workers and is shut off during winterizing.
I believe your rig is new enough to have 12 volt control for 120 volt operation. drawing 12 page 7. Manual

IF OPs water heater is an Atwood and it is a 2003 yr then it should have 120V AC directly to element on back of WH Tank with separate t-stats located with element.




Atwood changed/swapped to 12V DC control for the 2004 models


OP stated water heater works when plugged into a different 120V AC outlet using an extension cord.
SO issue is with power to that outlet




OP stated this AM
I found that one of the wires in the control box doesn't get 12 Volt
It could be a ground problem. There is also a faulty toggle switch.

PLEASE explain.
What control box....where is it located
What toggle switch are you referring to.

AND would you PLEASE post MODEL NUMBER (GC10A-XX etc)

IS it like this one.........4 pin connector on module in outside compartment


Or like this one..........4 pin & 6 pin connectors
