When your electronic-ignition heater won't light or the flame drops out, this OEM valve gets hot water flowing again. It fits the full E-series run and connects with standard 3\/8 inch flare fittings on 12 volt DC.\u003c\/p\u003e\n\n\u003cdiv class=\"nvn-description\"\u003e\n\u003cp\u003eWhen the hot water quits in your camper, the gas control valve is one of the first things a good RV tech checks. The Dometic 92078 is the genuine replacement gas valve assembly for Atwood and Dometic 6-gallon electronic-ignition water heaters. It's the same part the factory used, sold as a complete service kit so you're not chasing loose pieces. If your heater clicks but won't light, or the flame drops out a few seconds after it fires, a tired gas valve is a common culprit.\u003c\/p\u003e\n\u003cp\u003eHow do you know the valve's the issue? A few tells. The heater tries to light but never catches. It fires and then shuts down within seconds. Or it runs fine cold and quits once things warm up. Those point at a valve that isn't opening reliably or a solenoid that's giving up. It isn't the only thing that can cause a no-hot-water complaint, but on these tanks the gas valve earns its spot near the top of the checklist.\u003c\/p\u003e\n\u003cp\u003eThis valve fits a big family of heaters. The full list covers the G6A-2E, G6A-3E, G6A-4E, G6A-6E, G6A-7E, and G6A-8E, the GH6-3E, GH6-4E, GH6-7E, and GH6-8E, the GC6AA-7E through GC6AA-10E, the GCH6A-7E through GCH6A-10E, the GCH6-4E, and the G-9-EXT. That's the whole run of 6-gallon E-series tanks that used the 12 volt gas control. If your data plate shows one of those model numbers, this is your valve.\u003c\/p\u003e\n\u003cp\u003eWondering why it carries both the Atwood and Dometic names? Dometic bought Atwood's RV line years back, so the current part numbers wear the Dometic badge while the heater in your rig might still say Atwood. It's the same valve either way. You're getting the OEM part, not a guess-and-hope substitute that may or may not seal.\u003c\/p\u003e\n\u003cp\u003eThe plumbing side is straightforward. You get a 3\/8 inch male flare inlet and a 3\/8 inch male flare outlet, the standard connection on these tanks. The valve runs on 12 volt DC. On the E-series heaters, the ignition board energizes the valve's solenoid when it calls for heat, so there's no standing pilot to relight. When the board's happy and the valve's good, the burner lights and holds.\u003c\/p\u003e\n\u003cp\u003eInstalling it isn't hard if you're comfortable with LP gas fittings, but take your time. Use a proper flare wrench and snug the fittings firmly without gorilla-torquing them. Brass flare seats crack if you lean on them too hard. When you're done, brush a little soapy water on every joint and watch for bubbles before you trust it. That soap test catches small leaks far better than your nose does. And if you're not comfortable working on a propane system, hand this one to a certified RV tech. LP work is one place you don't cut corners.\u003c\/p\u003e\n\u003cp\u003eSo who's this for? It's the right part for an owner keeping an older Atwood or Dometic 6-gallon heater alive, or a tech stocking the shelf for a repair that walks in the door all season. Just know it's the gas control valve only. It won't fix a bad heating element, a rusted-out tank, or a dead circuit board. If you've already ruled the valve out, look there first before you swap it. But when the valve's the problem, this puts the genuine piece back in your hands and your hot water back on.\u003c\/p\u003e\n\u003cp\u003eOne more thing worth saying. When you've got the heater open for a valve swap, it's a good time to look over the rest of it. Check the burner tube for spider webs and mud dauber nests, which love those tubes and choke the flame. Give the flare fittings a wipe and inspect the gas line for cracks or chafe. A few extra minutes while you're in there can save you a second trip up the ladder later in the season.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul class=\"nvn-features\"\u003e\n  \u003cli\u003eGenuine Dometic 92078 OEM gas control valve, the same part the factory fitted so fitment and function match exactly\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch male flare inlet and 3\/8 inch male flare outlet, the standard connection on Atwood and Dometic 6-gallon tanks\u003c\/li\u003e\n  \u003cli\u003e12 volt DC solenoid valve, energized by the water heater's electronic ignition board on E-series models\u003c\/li\u003e\n  \u003cli\u003eSold as a complete service kit, so you get the valve assembly ready to install instead of loose pieces\u003c\/li\u003e\n  \u003cli\u003eFits the full 6-gallon E-series run: G6A, GH6, GC6AA, GCH6A, GCH6, and G-9-EXT models\u003c\/li\u003e\n  \u003cli\u003eDirect OEM replacement for a failed or leaking gas valve, a common fix for no-hot-water and flame-dropout complaints\u003c\/li\u003e\n  \u003cli\u003eCovers both Atwood-badged and Dometic-badged heaters, since Dometic now builds the Atwood RV line\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cdiv class=\"nvn-trust\"\u003e\n  \u003ch2\u003eWhy Buy from NVN Marine\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eAuthorized Dometic reseller, full manufacturer warranty\u003c\/li\u003e\n    \u003cli\u003eNMEA member and ABYC certified, advice from real boat techs\u003c\/li\u003e\n    \u003cli\u003eSame-day shipping before 3 PM ET on in-stock items\u003c\/li\u003e\n    \u003cli\u003eNY headquarters and Fort Lauderdale flagship retail store\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"nvn-faq\"\u003e\n  \u003cdetails\u003e\n    \u003csummary\u003eWhich water heaters does this gas valve fit?\u003c\/summary\u003e\n    \u003cp\u003eIt fits the Atwood and Dometic 6-gallon E-series heaters: G6A-2E, G6A-3E, G6A-4E, G6A-6E, G6A-7E, G6A-8E, GH6-3E, GH6-4E, GH6-7E, GH6-8E, GC6AA-7E through GC6AA-10E, GCH6A-7E through GCH6A-10E, GCH6-4E, and G-9-EXT.
