Find the right board.
Not a guess.

Type the part number stamped on your dead furnace control board to see the official universal replacement it cross-references to, sourced from ICM Controls and White-Rodgers manufacturer documents, not a listing title.

Furnace control boards switch 120/240V line voltage and the gas valve. This site is for identifying the correct replacement part only — it is not a wiring or installation guide. Improper installation can cause fire, electrical shock, or gas hazards; have a licensed HVAC technician do the actual replacement.

How this works

A furnace control board fails, and the OEM board that originally shipped with the furnace is often long discontinued. Rather than guess from a listing title, this site starts from your dead board's exact stamped part number and looks up the official universal replacement board that the manufacturer's own cross-reference documentation says covers it — the ICM Controls Cross Reference Guide and the White-Rodgers / Copeland Furnace Controls Reference Card, plus ICM's ICM2812-KIT cross reference. Every page on this site names the replacement board, its board type, and the exact document it came from — never a guess from a part number that merely looks similar.
