Furnace Control Boards
Furnace control boards are critical components that manage the heating cycles of your furnace, ensuring all functions operate smoothly and in the correct sequence. These boards play a vital role in maintaining optimal furnace performance by controlling ignition, flame detection, blower operation, and safety measures. Over time, furnace control boards can wear out or malfunction due to age, environmental factors, or electrical issues, necessitating replacement to keep your heating system functioning efficiently.

The Furnace Control Boards You'll Find Here
Universal Kits and OEM Fits That End Lockouts Fast
- Universal integrated kits that cover many models with one part like the White-Rodgers 21M51U-843. It includes a 120 V nitride ignitor and is designed to replace both 80 V and 120 V controls across multiple brands, with LEDs and adjustable fan delays to speed setup
- Honeywell universal IFC for single-stage furnaces, the S9200U1000, a go-to “one board solves most” option.
- OEM-specific replacements that drop right in: ICM280 for Goodman B18099-13S, ICM282B for Carrier HK42FZ, ICM2813 for Lennox, and ICM288 for Rheem 62-24084-82. Match the OEM part number and you’re back in heat.
- Non-integrated HSI modules (ignition only) when you’re not replacing the whole board, e.g., White-Rodgers 50E47-843.
- Harness-included “problem solvers” like ICM2812-KIT that ship with cable harnesses to replace the White-Rodgers 50M56U-843 and a long list of cross-refs.
How to Find Your Board Match
- Start with the part number. If you have the failed OEM number (e.g., HK42FZ-xxxx, B18099-13S), pick the listed OEM replacement or a universal kit that shows it in the cross-reference.
- Ignitor & line voltage. Some kits ship a 120 V nitride ignitor but are designed to replace both 80 V and 120 V systems. Verify in the kit specs.
- Stages & blower type. Choose single-stage vs. two-stage boards as required. Many universal kits include multi-speed PSC blower support and handy fan delay settings.
- Accessory outputs. Need humidifier or air cleaner outputs? Confirm they’re on the board you select.
Tip: when harness plugs don’t match, a universal kit with harnesses can save the call. No splicing mysteries, just plug-and-play.
