I have a Dometic 2193. It is actually a two lead element with the third wire being a ground. Just to be clear - I have been testing connectivity between either of the two element leads and the ground lead. And I get nothing, even when it is heated up and popping GFCI breakers. When it does pop a breaker I quickly test the connectivity and then reset the breaker - but it won't stay on until after it cools 5-10 minutes. I would think that when it is warmed up and in its behavior pattern of popping the breaker, that I would sense at least SOME connectivity between the element leads and ground. But that is not what I see. Anyway, new element is on order...
