Carrier LH680512 Electrode Assembly

The Carrier LH680512 Electrode Assembly is a high-precision OEM ignition component designed to provide a consistent high-voltage spark for gas furnace pilot burners. Engineered for Carrier, Bryant, and Payne residential heating systems, this pilot burner spark electrode ensures reliable ignition cycles by maintaining fixed gap tolerances and thermal resistance. As a veteran-grade HVAC replacement part, it features a durable ceramic insulator and a robust mounting bracket (3/4" L x 1/2" W) that stands up to the intense heat within the burner box. Replacing a fouled or cracked furnace igniter electrode with this genuine LH680512 assembly restores system timing and prevents common lockouts caused by weak spark intensity or flame-sensing failures. Its 1/2" electrode length is specifically calibrated for a drop-in fit in models such as the 58DH and 301289 series, eliminating the need for field modifications and reducing labor time on the job site.

• OEM Compatibility: Exact replacement for Carrier LH680512, ensuring seamless integration with Bryant and Payne gas-fired furnaces.
• High-Temperature Durability: Constructed with industrial-grade ceramic and heat-resistant alloys to prevent electrical leakage and electrode degradation.
• Precise Ignition: Maintains critical spark-to-burner spacing, reducing ignition delays and preventing unburned gas accumulation.
• Contractor-Ready Design: Features an integrated mounting bracket for secure, vibration-resistant installation in pilot burner assemblies.

Is the Carrier LH680512 a universal part?
No, this is a specific Carrier OEM electrode. While it fits many Carrier, Bryant, and Payne models, you must verify your specific model number (e.g., 58DH, 58SC) to ensure a correct fit.

What are the signs of a failing electrode assembly?
Technicians typically look for a clicking sound without ignition, visible cracks in the ceramic insulator, or heavy carbon buildup that prevents a strong spark from jumping to the burner surface.

Does this assembly include the high-voltage lead?
This part is the electrode and bracket assembly. We recommend inspecting your existing ignition wire for signs of brittleness or heat damage when replacing the electrode to ensure a complete circuit.
