ICM CONTROLS Universal Replacement Furnace Control Board Kit ICM2812-KIT

The ICM ICM2812-KIT is a low-cost universal Hot Surface Ignition (HSI) furnace control that replaces White-Rodgers 50M56U-843 and 200+ OEM boards. The kit includes the control plus a set of cable harnesses so you can match the original connector instead of cutting and splicing. That cuts install time and reduces callback risk on common Goodman, Carrier, Lennox, York, Trane, Rheem, Nordyne, and White-Rodgers furnaces.

A microprocessor-based board runs the full heat sequence: inducer timing, ignitor warm-up, trial for ignition, flame sensing, gas valve control, blower delays, and lockout. Built-in LED status and fault codes speed diagnosis on the job. 100% lockout safety and compatibility with natural gas or LP keep the replacement in line with typical residential gas furnace operation. Use it when the original board has failed and you want one stocked kit that covers a wide range of single-stage HSI applications.

Always match the original part number and furnace wiring diagram before install. Some Rheem/Ruud units without a separate flame sensor need Rheem flame sensor kit 62-24044-71. Follow ICM harness notes for Trane/American Standard and certain York models. Professional installation is recommended.
