The Dometic 31098 is a 12V DC gas valve designed for top-mount installation on select Dometic absorption refrigerators. This small-profile gas valve controls the flow of LP gas to your refrigerator's burner assembly, enabling automatic ignition and flame control when operating in gas mode. If your RV refrigerator won't ignite on gas, cycles repeatedly, or shows error codes related to gas operation, a faulty gas valve is often the culprit.
This genuine OEM replacement part ensures reliable gas mode operation for your Dometic refrigerator, whether you're boondocking off-grid or simply prefer LP operation. The top-mount configuration and compact size make it suitable for specific Dometic models with space-constrained installations.

Frequently Asked Questions
Q: How do I know if my gas valve needs replacement?
A: Common symptoms include the refrigerator failing to ignite on gas mode, repeated clicking without ignition, error codes related to gas operation, or the refrigerator working on AC but not LP gas. If you hear the igniter clicking but no flame appears, or if the flame goes out shortly after ignition, the gas valve may be faulty.
Q: What's the difference between top-mount small and other gas valve configurations?
A: The "top-mount small" designation refers to both the mounting position (above the burner) and the physical size of the valve body. This compact design is used in specific Dometic models where space is limited. Always verify your current valve's configuration before ordering to ensure proper fit.
Q: Can I install this gas valve myself?
A: Installation requires working with LP gas connections and 12V wiring. If you're comfortable with basic RV repairs and follow proper safety procedures (turn off gas at the tank, disconnect battery), many RV owners successfully replace gas valves. However, if you're unsure about working with gas systems, professional installation is recommended for safety.
Q: Will this work with my Dometic refrigerator model?
A: This valve fits specific Dometic absorption refrigerator models that use a top-mount small gas valve configuration. Check your refrigerator's model number and current gas valve part number to confirm compatibility. The valve is typically located behind the lower access panel on the exterior of your RV.
