Dometic 92100 Water Heater Gas Valve Assembly

The Dometic 92100 Gas Valve Assembly is an OEM replacement gas system designed for select Dometic WH-series RV water heaters. The assembly includes the solenoid gas valve and burner tube responsible for controlling propane flow and delivering fuel to the burner during the ignition and heating cycle.

A failed gas valve may prevent propane from reaching the burner, causing the water heater to click without igniting, shut down during startup, or operate only in electric mode. Replacing the gas valve assembly can restore proper propane delivery and reliable burner operation when testing confirms the existing valve is not opening or regulating gas correctly.

This is a model-specific Dometic replacement assembly and should not be used as a universal gas valve for older Atwood or unrelated Dometic water heaters.

Models It Fits

• Dometic WH-6GA 6-Gallon Gas Water Heater
• Dometic WH-6GEA 6-Gallon Gas/Electric Water Heater
• Dometic WH-9GEA XT Water Heater

Dometic part number: 92100

Although the product is commonly described as fitting Dometic WH-6 gallon water heaters, published compatibility also includes the WH-9GEA XT.

Signs You May Need This Part

• The water heater clicks but does not ignite on propane
• The burner does not receive propane
• The water heater works on electricity but not gas
• The burner lights intermittently
• The burner ignites and then shuts down
• The gas valve does not click or open during the ignition sequence
• The valve receives proper voltage but does not release propane
• Burner output is weak or inconsistent
• The gas valve or burner tube is visibly damaged or corroded
• Electrical testing confirms an open or failed solenoid
• The water heater repeatedly enters ignition lockout

Similar symptoms may also be caused by an empty propane cylinder, low gas pressure, air in the propane line, a blocked burner orifice, damaged wiring, a faulty igniter, poor grounding, or a failed control board. Confirm that the valve is receiving the correct voltage before replacing the assembly.

Estimated Installation Time

Approximately 30 minutes to 1 hour.

Installation time may vary depending on water-heater accessibility, the condition of the propane connection, mounting hardware, and whether corrosion or debris is present around the burner compartment. After installation, check the burner alignment, confirm proper ignition, and test all disturbed propane connections for leaks.
