When your Dometic absorption refrigerator stops cooling on propane, the gas valve or burner assembly is one of the first components to suspect. This OEM Dometic part 3850730569 is a direct-replacement gas valve and burner assembly designed to bring LP-mode performance back to your rig without guesswork. At just 0.1 lbs and measuring 6.25 x 4.0 x 1.5 inches, it is a compact, proven component built to Dometic factory specifications.
Dometic absorption refrigerators -- found in millions of Class A, Class B, Class C motorhomes, fifth wheels, and travel trailers -- use an LP gas burner to heat the ammonia-water solution that drives the cooling cycle. Over time, the gas valve can fail to open or close properly, the burner orifice can clog or corrode, and the burner tube can warp from heat cycling. The result is a refrigerator that runs fine on 120V shore power but refuses to cool on gas -- a serious problem for boondockers and dry campers who depend on propane.
Part 3850730569 replaces the complete gas valve and burner assembly as a single unit, so you are not chasing individual components. Using a genuine Dometic OEM part ensures the orifice size, valve flow rate, and burner geometry all match what the cooling unit was engineered for, protecting your refrigerator's long-term performance.
Manufactured to Dometic factory specifications for a bolt-in installation with no adapters or modifications required on compatible models.
Addresses the most common cause of LP cooling failure -- a faulty gas valve or fouled burner -- in one replacement part.
Measures 6.25 x 4.0 x 1.5 inches and weighs just 0.1 lbs, making handling and installation in tight refrigerator compartments straightforward.
Restoring propane operation is essential for boondockers and dry campers who cannot rely on shore power or solar alone for refrigeration.
Dometic (formerly Electrolux/Dometic) has produced absorption refrigerators under the RM and NDR series designations for decades. The gas valve and burner assembly on these units is a wear item -- the valve diaphragm or solenoid degrades over years of heating and cooling cycles, and the burner can accumulate carbon or rust scale that disrupts the flame pattern.
Part 3850730569 is associated with Dometic's RM series absorption refrigerators commonly found in RVs from the early 2000s through recent production years. Always verify compatibility by cross-referencing your refrigerator's model and serial number on the data plate inside the fresh food compartment or on the exterior access panel before ordering.
Before ordering, confirm the burner assembly is the source of your LP cooling problem. Common symptoms include:
Replacing the gas valve and burner assembly is a manageable DIY repair for RV owners comfortable working with LP gas components. The assembly is accessed through the exterior refrigerator vent panel -- no need to remove the refrigerator from the cabinet in most installations.
