Propane furnace air intake

[Fortj1114]

Hi, I have a 2019 airstream intl signature 30 ft with a rear queen bed. My furnace was just repaired and they said they cleared debris from the air intake under the stove or
Somewhere near there. After operating a few days, the same problem arose. Where is the actual air intake located, how do I get to it, and any suggestions in clearing it out? I am able to see a flexible hose below the stove and the cabinet between stove and sink.

Thank you.

Access depends on location of furnace. This is the location of intake on furnace in general.

Viewed from outside of furnace open the access inspection doors.

See the control panel on the left side, now look behind it and farther in, see louvers? Vent may also be on top but it’s close to the outside.

If unit is under sink for example remove drawers and look behind hoses. Or maybe remove a shelf under sink. As I don’t know where or what your trailer layout is can’t point just describe possibles.

If you see any pics of furnace hot air comes out thru round holes cold air return is thru louvers.

Curious what was symptom of problem?
