For your Atwood water heater number gc6aa-10e, it sounds like you have either a wiring issue or an element issue. To determine if a replacement is needed you will want to make sure the connections are good to and from your switch. I recommend using a multimeter like # PT89ZR to check your wiring. If the wiring is good to your element, then you will want to replace the electric element and you should be good to go.

@Earwin Hey Earwin! Check out the Q&A page I linked below. On that page there's a decent wiring diagram that shows all the connections for that Atwood unit. This should give you a good idea of where to look - you just want to check for any frayed wiring or loose connections. Is the unit not working at all?
