Carrier 50HJ403022 Ignitor Assembly

Eliminate ignition lockout errors and restore reliable combustion with the Carrier 50HJ403022 Ignitor Assembly. Engineered as a direct OEM replacement for 48VL400002, this furnace ignitor is critical for maintaining the sequence of operation in Carrier, Bryant, and Payne package units and rooftops. As a veteran-grade HVAC replacement part, it provides a consistent, high-temperature spark or glow required to ignite gas across the burner crossover tubes safely and efficiently. If you are seeing a 5-flash code on the integrated ignition control board, it often indicates a faulty ignitor that has reached the end of its duty cycle due to thermal fatigue or cracked silicon elements. This assembly typically installs without a wire harness, fitting directly into the burner bracket with standard 1/4-inch fasteners. Choosing a genuine Carrier ignitor ensures the precise resistance levels necessary to prevent premature electrode wear and nuisance trips, keeping your client's equipment operational during peak heating demands.

• Direct OEM Compatibility: Specifically designed to replace obsolete part number 48VL400002 without field modifications.
• Enhanced Ignition Reliability: Provides the high-wattage heat or spark required for immediate gas ignition, preventing unburned fuel accumulation.
• Optimized for Carrier RTUs: Validated for use in popular models like the 48HCEA071A and 48TC series to maintain factory safety certifications.
• Durable Construction: Built to withstand the extreme thermal cycling of commercial and residential heating stages.

How do I verify if my ignitor assembly is defective?
Use a multimeter to check the resistance (ohms) across the leads. If the circuit is open or the resistance is significantly outside the manufacturer's specified range, the element is compromised and requires replacement.

Will this work if my unit is currently in lockout mode?
Yes, but you must reset the control board after installation. A failed ignitor often triggers a "3-trial" lockout; replacing the faulty 50HJ403022 and cycling power will allow the system to resume its normal ignition trial.

Does this assembly include the flame sensor?
No, this is the ignitor assembly only. While the ignitor initiates the flame, the flame sensor (often part number 50HJ401431) monitors the combustion. It is best practice to inspect both during a no-heat service call.
