Carrier furnace control board replacement

Every Carrier furnace control board FitXref covers (19 part numbers) cross-references to one of these official universal replacements. Find the number stamped on your board below to open its replacement page and source.

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.
