I have Atwood water heater on Winnebago Access (model gchga-10e) which is the 6gal combo gas/electric. Gas works fine, but the electric is not working. Symptoms: switch will not illuminate for the 110 and water doesn't appear to heat. I ASSUME that element is toast, but with the Atwood the element is on backside of unit (inside of cab) which makes replacement really difficult. I could pull it out, but that is last option and I was hoping that I might have overlooked something really simple. I checked all breakers and all good and I would put a probe on the element, but it is just to difficult without pulling it out of the unit. Any suggestions?
