What's wrong?
The Norcold N306 mini refrigerator in the 2017 Trail Boss Twister Horse Trailer uses a propane gas valve to control fuel flow when the refrigerator runs on propane. The test port is a small service opening on that valve. A technician uses it to check gas pressure, then the screw seals the opening so propane stays inside the valve.
On the recalled trailer, that test port screw is loose or missing. Without a tight screw, the valve is not sealed at the service port. Propane gas can escape from that opening instead of staying contained in the refrigerator fuel system. The defect is tied to the refrigerator installed in one living-quarters conversion.
There is no warning sign before failure. Do not rely on smell, sound, or refrigerator performance to confirm the defect. The recall inspection is what tells the dealer whether the propane valve test port screw is secure.
