Product Description P/N: 345606-75103
Description
The Carrier 345606-75103 is a genuine OEM replacement control board kit engineered to restore full operational functionality to compatible Carrier, Bryant, and Payne HVAC systems. Functioning as the central logic center for the unit, this board precisely coordinates the startup and shutdown sequences of critical heating and cooling components. By maintaining strict control over ignition, blower timing, and safety sensors, the control board ensures the entire system operates at peak thermal efficiency while preventing hazardous electrical or gas-related failures.

Information About 345606-75103BCM-MS/TP
Often distributed as a complete repair kit to replace older factory iterations (such as the HK38EA011), the 345606-75103 includes the primary HK38EA056 printed circuit board, a specialized mounting bracket, necessary sheet metal screws, and installation instructions. HVAC technicians heavily rely on this exact OEM kit because it eliminates the dangerous guesswork and complex rewiring often associated with universal aftermarket boards. The board features an integrated diagnostic LED that flashes distinct fault codes, allowing service personnel to rapidly troubleshoot system lockouts, limit switch trips, or ignition failures directly at the equipment panel.
Key Features:
● Genuine OEM Precision: Manufactured to Carrier’s strict engineering standards, guaranteeing a flawless mechanical fit and exact electrical compatibility with existing HVAC units.
● Coordinated System Operation: Precisely manages the timing of the inducer motor, gas valve, hot surface ignitor, and main blower to ensure smooth, reliable thermal cycles.
● Complete Installation Kit: Includes the primary circuit board, a custom mounting bracket, mounting hardware, and factory instructions to facilitate a rapid, secure retrofit.
● Active Diagnostic Interface: Features a built-in flashing LED system that clearly communicates specific fault codes, drastically reducing troubleshooting time during service calls.
● Advanced Safety Monitoring: Continuously evaluates input from flame sensors, limit switches, and pressure switches to instantly shut down the unit during unsafe conditions.
● Direct-Fit Architecture: Engineered as a true drop-in replacement, allowing service professionals to quickly swap out malfunctioning controllers without cutting or splicing factory wiring.
The 345606-75103 delivers the digital intelligence and electromechanical reliability required to maintain safe, efficient, and uninterrupted operation in modern residential and light commercial HVAC systems.
