OFFICIAL CROSS-REFERENCE

Furnace control board model index

Every OEM board number below cross-references to an official universal replacement from the ICM Controls Cross Reference Guide (LIAF309-2) or the White-Rodgers / Copeland Furnace Controls Reference Card (R-4952, 3/24). Open any board number for its full replacement page and sources.

Furnace control boards switch 120/240V line voltage and the gas valve. This page 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.
