What's wrong?
The Dometic 3 burner range and oven in the 2019-2021 Host Campers Cascade, Rainier, Tahoe, and Mammoth trailers uses LP gas for cooking. At the stove connection, a saddle valve helps secure and control the gas path into the appliance. An O-ring is the small rubber seal that keeps gas from escaping around that connection.
On affected trailers, the saddle valve securing bolt can be tightened too far. That extra force damages the O-ring instead of letting it seal evenly. Once the seal is damaged, gas can leak continuously from the cooking stove assembly, even when the owner has not started cooking. The repair corrects the overtightened O-ring condition so the gas connection seals as intended.
An owner can notice a gas smell in or near the camper. Treat that smell as the warning sign, because leaking LP gas increases the risk of fire.
