I called Dometic yesterday to get more information about the possibility of the electric heater putting out too much heat and causing the weld fracture. I made some measurements of the AC current and voltage of my heater and got 360-372 watts. The tech, Roger, said that was within the acceptable range and it was not a concern. He said that the heat from the propane burner was greater than the electric heater and it would be the one to cause a weld fracture and not the electric heater for the above electric heater output. I calculated my heater resistance to be between 41.5 and 43 ohms.
