035-20714-001 Rev. D (1105) 7 of 8 Note: These furnaces were manufactured with two different style front access panels, items #25 and #26. The original design required unscrewing door knobs (item #51) to remove the panels. On the newer design the panels are held in place with magnets and the knobs are only used for pulling off the panels. Please check the style panels the furnace is supplied with before ordering parts. Newer design parts have magnet as part of the description.
