My Atwood furnace has a reset button located behind the metal grill exhaust cover. With it tripped it did exactly as you describe. Fan would blow cold air for a minute or so then shut off. A bad igniter will cause a similar issue.
There is also a high temp limit (Sail) switch that would cause the OP's issue if bad.
So your furnace also just had the exhaust vent on the outside no door lower and your saying you took that small square exhaust vent off and there was a reset behind that exhaust ?
My furnace looks similar to this photo. Removing the cover exposed the wiring with a small inline reset switch.
