and the furnance goes BOOM

I have a Carrier model 58EG100211 natural gas furnace and I believe the burner is dirty. Not always, but many times it will ignite with a loud "explosion." The area is too cramped to get a steel brush in there and the Carrier website does not carry any info on this model. Is there an easy way to remove the burners for cleaning or is all I need is an old toothbrush "on a stick"? Also, the flames are yellow at the top.

The whole rack of burners comes out as a unit.

No doubt the burners need to be cleaned, but the cause of the delayed ignition problem you describe is probably that the pilot burner needs to be taken apart and the pilot burner and pilot orifice need to be cleaned.

To get at the pilot orifice, remove the brass ferrule at the bottom of the pilot burner with a 7/16" wrench.
