What's wrong?
The cooking stove in these 2019-2020 Highland Ridge Tt Mesa Ridge, Open Range, Silverstar, and Highlander trailers is a Dometic 3 burner propane appliance. Its gas valve controls the flow of propane to the burners, and the O-ring seal is supposed to keep gas inside the valve body when the stove is off or operating.
On the recalled R1731 and R2131 stoves, the saddle valve securing bolt was tightened too far during assembly. That extra force can damage the O-ring seal. Once the seal is damaged, propane can leak continuously from the valve area instead of staying contained inside the stove gas system.
There is no warning sign before failure. If you smell gas near the stove, stop using the appliance and keep flames, sparks, and ignition sources away until a Highland Ridge Tt dealer inspects it.
