the furnace should be fine the high temp limit switch measures the temp of the combustion chamber not the heat output of the furnace and its already sucking in 85° air for combustion from outside it does not take much to get the combustion chamber past the limit.
Huh? The high limit is inside the heat output duct box.
I dont think there is a high limit in the combustion chamber. Just the igniter and flame sensrr.
I just did another temp probe of a closer duct output and it was some 200f plus..
The intake air I was measuring temp at was the room intake around the unit itself.
The outside intake seems to be sucking in air normally..
