What's wrong?
The cooktop in a 2021 Highland Ridge Tt Open Range is the interior stove used for cooking inside the trailer. Its burner flame is supposed to stay above the cooktop burner while the furnace operates separately, with the cabinet seal keeping furnace airflow from disturbing the stove flame.
On affected trailers, the cooktop is installed in a cabinet that is not fully sealed from the furnace area. Highland Ridge traced the problem to a furnace change that created negative pressure when the Suburban furnace and stove ran at the same time. That means airflow pulls the burner flame the wrong way instead of letting it stand where it belongs.
Owners can see the problem. An inverted flame on the cooktop while the furnace is running is the warning sign. If you see the flame pull inward or behave differently from a normal cooktop flame, turn the cooktop off and have the trailer checked before using the stove and furnace together again.

What's the safety risk?
An inverted cooktop flame can increase the risk of fire. If you see the flame pull downward or burn in an unusual direction, stop using the cooktop and schedule the recall repair. Keep the appliance off until the dealer completes the work. Repair is free at any franchised Highland Ridge Tt dealer.

What happens at the repair
At the dealer, a Highland Ridge Tt technician installs sealant and plywood panels where the cooktop cabinet needs added separation from the furnace area. The recall repair is free, including parts and labor.
