Dometic 92104 Water Heater Igniter, Electronic Replacement for WH-6GA / WH-6GEA

Dometic 92104 Replacement Igniter is the genuine part that gets it working again. It’s built specifically for the Dometic WH-6GA, WH-6GEA, and WH-9GEA series gas water heaters, so it drops into place with the correct spark gap and fit the factory intended. The igniter is the small component responsible for the automatic spark that lights the burner. Over time, exposure to heat, moisture, road vibration, and repeated cycling can crack the electrode, corrode the tip, or damage the wire, leaving you with a unit that clicks but won’t light, sparks weakly, or won’t spark at all. When that happens, no hot water. Swapping in a fresh 92104 restores dependable, hands-free ignition so the burner lights the way it should. Because it’s a genuine Dometic OEM part, you’re getting the exact spark characteristics and dimensions your water heater was designed around, a big advantage over generic substitutes that may not spark consistently or seat correctly. The attached ignition wire is included, which matters because the wire itself is a frequent failure point; replacing the igniter and wire together means you’re renewing the entire spark path in a single repair.
GENUINE DOMETIC OEM PART: Matches factory specifications for correct fit, spark gap, and function — no guesswork or adaptation required
AUTOMATIC ELECTRONIC IGNITION: Restores the hands-free spark that lights the burner, so you get hot water on demand without manual lighting
INCLUDES IGNITION WIRE: Comes with the attached ignition wire, a common failure point, so you replace the whole spark path in one part
A COMMON FIX FOR NO-IGNITION / NO-HOT-WATER COMPLAINTS: If your water heater clicks but won’t light (or won’t spark at all), a worn or cracked igniter is one of the first components to check and replace
