What's wrong?
The refrigerator roof vent on a 2021 Heartland Mallard or North Trail trailer is the opening and cap that let heat and combustion gases leave the refrigerator area. When an LP gas refrigerator runs, it needs a clear path for ventilation through the roof so hot air and exhaust do not collect inside the unit.
On affected trailers, Heartland says production did not cut the proper ventilation hole in the roof or ceiling during manufacturing. The vent cap hardware is the named part, but the roof opening was not routed correctly, so the refrigerator lacks the ventilation path it was designed to use. The remedy is to install the roof vent base and roof vent cap so the refrigerator has proper roof ventilation.
Owners can notice the smell of LP gas inside the unit, especially around the refrigerator, or a refrigerator that is not cooling properly. Treat those as warning signs and keep the area ventilated until the recall repair is completed.

What's the safety risk?
An improperly routed refrigerator vent can let the refrigerator overheat, increasing fire risk. Exhaust gas trapped inside the vehicle can also cause carbon monoxide poisoning, which increases the risk of injury or death. Treat LP gas smell near the refrigerator or a refrigerator that stops cooling as a reason to stop using the unit and call the dealer. Repair is free at any franchised Heartland dealer.
