Nidec-US Motors 2130 Motor
The White-Rodgers 50A55-843 is a universal integrated furnace control designed specifically for Goodman and Amana applications, providing a direct replacement for various 768A silicon carbide ignition systems. This microprocessor-based ignition control manages the hot surface ignitor, blower motor timing, and gas valve sequencing with high precision. It features a diagnostic LED indicator that flashes specific codes to simplify furnace troubleshooting on the job site. The board is engineered to handle single-stage heating cycles while monitoring safety circuits, including limit switches and pressure switch closures. Its universal mounting hardware and comprehensive wiring harness adapters ensure a seamless retrofit, maintaining OEM-level heating system performance. Built with low-voltage 24V inputs and heavy-duty relay outputs, this module is the go-to stock item for technicians servicing intermittent pilot and direct ignition furnaces.
Key Benefits
- Direct OEM Replacement: Designed for an exact fit in Goodman, Amana, and Janitrol furnaces, eliminating the need for complex field modifications.
- Advanced Diagnostics: The onboard LED status light provides instant feedback on system faults, significantly reducing service call diagnostic time.
- Selectable Blower Delays: Features adjustable heat-off delay settings to optimize airflow efficiency and prevent cold drafts at the start of a cycle.
- Rugged Reliability: Constructed with industrial-grade components to withstand high-temperature environments within the burner compartment.
Common Questions
Will this board work with my existing 80-volt ignitor?
The 50A55-843 is specifically designed as a 95V / 120V ignition control. If you are replacing an older 80V system, you must ensure you are using a compatible silicon carbide ignitor as specified in the cross-reference guide.
How do I clear the lockout codes on this module?
Standard lockout reset occurs by cycling the 24V power to the board or by a manual reset of the thermostat's heat call. The board also features a self-test routine to verify all outputs are functional upon installation.
What does a rapid-flash LED indicate?
A rapid flash typically signifies a reverse polarity issue on the 120V line or an improper chassis ground connection, which is critical for flame rectification sensing.
