Refrigerator exhaust fumes inside?

[geewizard]

We bought a used 2011 172.

When running the refrigerator on LP, we smell exhaust fumes inside the trailer. It seems to be sealed well when I look inside the outside vents.
The AC vents, bathroom vent, and windows are all closed so the fumes must be coming in alongside the refrigerator.

Is this a known issue?

Hello, it is a problem they are having. Above the refer there is a gap in the gasket. Your dealer will have to seal it.
