If your RV's Atwood water heater isn't lighting or has gas valve issues, this might be the part you need. This is a brand new replacement gas valve assembly for Atwood water heaters. It fits models like the GC6AA-9E, GC6AA-10E, GC10-1E, GC10-2E, and GC10A-2E (and probably other similar ones in those series). The MPN listed is GC10A-2E and GC10A-3E. Made by Atwood. Comes in original packaging (likely Atwood's). No UPC. This is a critical safety component, so if you're not comfortable working with gas lines, it's best to have an RV tech install it. But if you're a DIYer and know your way around your water heater, this genuine Atwood valve is the right part to get your hot water working again. Always double-check the model number on your existing unit.
