While showing a friend the ropes on their recent purchase, I noticed when I got ready to explain the water heater operation that the the electric side switch was in the on position and the AI was plugged in to shore power and had been for a couple of hours. The water heater was dry so I wonder if the element is burned out or if there is a safety device to prevent operation if empty. And when on generator power, there was no current draw (breaker wasn't tripped) which would indicate a problem. But the Atwood site says:
Each Atwood electric water heater is
equipped with a high quality 120 volt/
1400 watt incalloy
designed to withstand accidental
operation in an empty tank.
The propane side didn't work either. Did notice that what appeared to be a thermal fuse in a clear sleeve on the right side near the electronics. The sleeving appeared to have been subjected to high temperature. Looked similar to this:
Glass half full or half empty to an engineer is simply a glass that was over designed.
