Did an inspection today and while checking the furnace, I noticed this on the 3 right burner elements.
These burners were also very orange while the 2 on the left were blue as I would expect.
This a Carrier furnace from approx. 1994.
Would the ash (I assume that's what the white material is) and the orange flame be indicative of a venting issue?
