What's wrong?
The Winn-Tec LP regulator on affected 2016-2021 Grand Design Imagine, Momentum, and Transcend travel trailers controls propane pressure between the LP tanks and the appliances. It is supposed to reduce tank pressure to a steady lower pressure so the refrigerator, stove, and other LP appliances burn with a controlled flame.
On these trailers, an oily plasticizer from the LP hoses can collect inside the regulator. That oil breaks down the diaphragms and seals that separate the high-pressure and low-pressure sides. When the seal no longer holds, high-pressure LP gas passes downstream to an appliance, which raises the flame and creates a fire risk.
Before failure, owners can hear a hissing sound at an LP appliance or see a larger flame than normal. Treat either sign as a reason to stop using the LP appliance until the recall repair is complete.
