What's wrong?
The RV oven in the 2020 Trails West Sierra uses a Dometic 3-burner cooking stove fed by the trailer's LPG system. A saddle valve controls gas flow at the oven manifold, the metal passage that sends fuel toward the burners. An O-ring sits at that joint as a rubber seal, keeping gas contained when the stove is off or in use.
On the recalled oven, the saddle valve securing bolt was tightened too much during assembly. That extra force damages the O-ring seal between the saddle valve and the manifold under the burner surface. Once the seal is damaged, gas can leak continuously at that joint instead of staying inside the fuel path.
There is no warning sign before failure listed for this defect. The stated concern is an increased risk of fire in or around the oven if leaking gas reaches an ignition source.
Who's affected?
The issue centers on the RV oven and its LPG saddle valve O-ring, listed under both LPG system and oven/stove/cooktop components.
