Copeland Comfort Control (White Rodgers) 50M56U-751 Module Replacement Kit
The White-Rodgers 50M56U-751 is a commercial-grade universal integrated furnace control replacement kit designed for single-stage HSI systems. This 24V module serves as a direct drop-in for Carrier and ICP boards, specifically replacing part numbers like 1186024, HK42FZ011, and 325878-751. Built for the field, it features a self-test installation routine to verify inducer, igniter, and blower functionality immediately upon swap-out. The board supports PSC blower motors and provides dedicated 120V outputs for electronic air cleaners and either 24V or 120V humidifiers, eliminating the need for external relays.
For advanced troubleshooting, the tri-color diagnostic LED offers fault recall, displaying up to 11 additional codes to pinpoint systemic issues like limit trips or flame rollout. This kit includes the necessary 9-pin and "flip" adapter harnesses to bridge compatibility between legacy block plugs and modern 11-pin in-line factory wiring. With an operating range from -40°F to 175°F and a replaceable automotive-style fuse for low-voltage protection, this furnace control board kit ensures reliable performance in demanding residential and light commercial applications.
Key Benefits for Contractors
- Universal Carrier/ICP Compatibility: Consolidates inventory by replacing over 33 OEM part numbers including the Carrier furnace board 50M56U-751.
- Streamlined Installation: Includes all required adapter harnesses and mounting screws for direct OEM replacement without rewiring.
- Flexible Airflow Management: Supports low-speed continuous fan operations and multiple speed taps (Cool, High Heat, Low Heat) for precision air balancing.
- Enhanced Field Diagnostics: Features a pushbutton to display stored fault codes, facilitating faster repairs and reducing callbacks.
- System Protection: Microprocessor-controlled timings (30s pre-purge, 17s igniter warm-up) ensure safe ignition sequences and equipment longevity.
Common Questions
Can this board replace a two-stage furnace control?
No, the 50M56U-751 is strictly for single-stage HSI integrated furnace controls. It is not compatible with two-stage or modulating gas valves.
Are adapter harnesses required for all installations?
The kit includes multiple harnesses to match specific OEM connections. If your existing furnace control module uses a different pin configuration, use the included 11-pin or 9-pin adapters as specified in the cross-reference guide.
Is twinning supported with this module?
This board can be twinned only with another 50M56U-751 (black cover models). It cannot be twinned with original Carrier OEM boards or other different part numbers.
