White Rodgers 50F06-843 Control Board

The White Rodgers 50F06-843 Control Board is a high-performance Universal Furnace Fan Timer designed for single-stage systems utilizing PSC inducer and blower motors. As a heavy-duty furnace control board replacement, this unit provides a direct service solution for various legacy models, including the ICM270, Honeywell ST9120, and Robertshaw 695-003. Its non-integrated architecture allows it to interface seamlessly with independent ignition modules or intelligent gas valves, making it a versatile HVAC replacement part for over 150 OEM configurations.

Engineered for field reliability, the 50F06-843 features a tri-color LED diagnostic system to simplify furnace troubleshooting by providing clear status and fault codes. The board supports both 115V and 230V line voltage inputs and includes specialized terminal flags and multiple mounting hole options to ensure a secure fit in the existing cabinet without modification. For contractors managing heating and cooling maintenance, the exclusive fault recall button allows for rapid retrieval of previous error codes, significantly reducing diagnostic time on the job site.

• Extensive Cross-Compatibility: Replaces over 150 competitive part numbers including various Honeywell ST9101, ST9120, and ST9160 series.
• Simplified Wiring: Includes harnesses with terminal flags and provides both 1/4" and 3/16" transformer connections for a true drop-in installation.
• Advanced Diagnostics: Tri-color LED and fault recall button assist in identifying issues with pressure switches, limits, or voltage fluctuations.
• Twinning Capability: Supports twinning of two boards for larger air handling requirements, provided both units are from the same manufacturer.
• Broad Application: Compatible with Direct Spark Ignition (DSI), Hot Surface Ignition (HSI), and SmartValve systems.

Is the 50F06-843 a direct replacement for an ICM270?
Yes, this unit is the engineered direct replacement for the ICM270. It maintains the same logic for dual-function fan timing and safety monitoring while offering superior diagnostic feedback.

Can I use this board with a 230V system?
The 50F06-843 is rated for both 115VAC and 230VAC line voltage, making it suitable for a wider range of furnace and package unit applications.

How do I clear stored fault codes?
Fault codes can be cleared by pressing and holding the fault recall button for 5 to 10 seconds. Always document the codes before clearing to ensure accurate system history.
