Gc 10a 3e water heater replacement

How hard is it to wire the new gc10a4 into my camper mine the gas side is bad and element for 120 volt is frozen in and will not bust loose?
  • Read about the 'conversion' on pgs 23,24 & 25 in this Atwood Manual

    Atwood Water Heater Service Manual

    Your old version used 120V AC DIRECTLY to element and is no longer available

    New version used DC for On/Off switches, DC Circuit Board, shared set of t-stats for heat control and DC to trigger the 120V AC to element


    Don't know what RV/Camper you have but must be 2003 vintage or older
  • Thank you. So it looks like a new heater will come with switch also

    Depends on 'where' it is purchased.

    Some come with DOOR and DUAL Switch

    Some Neither

    Some just DOOR


    Read ALL of the fine print on those Internet ADs
