Lochinvar & A.O. Smith 100110701 Flame Rod

The Lochinvar & A.O. Smith 100110701 Flame Rod is a critical OEM heating system replacement part engineered for high-precision flame rectification in residential and commercial boilers and water heaters. As a veteran-grade HVAC flame sensor, this component facilitates the essential DC microamp signal required by the ignition control module to confirm burner presence and prevent unsafe gas accumulation. Designed specifically for compatibility with Lochinvar and A.O. Smith gas-fired appliances, it serves as the direct replacement for 100110701 (formerly 9005886215). The rod features a high-grade ceramic insulator to prevent electrical leakage and a durable alloy probe capable of withstanding consistent high-heat exposure. For technicians performing an outdoor reset or standard maintenance, replacing a fouled or cracked rod with this genuine 100110701 flame sensor ensures the system maintains peak operational reliability and meets strict safety protocols without the risk of nuisance lockouts or intermittent ignition failures.

Key Benefits for the Contractor

• Universal OEM Compatibility: Direct replacement for several Lochinvar and A.O. Smith models, ensuring a precise fit without field modifications.
• Enhanced Signal Stability: Engineered to provide a consistent 0.5 to 10 microamp (µA) DC signal for reliable flame proving and reduced troubleshooting time.
• Rugged Construction: Industrial-grade flame sensor assembly designed to resist carbon buildup and oxidation in high-temperature combustion chambers.
• Critical Safety Compliance: Restores the primary safety circuit for flame detection, eliminating the risk of unburned gas discharge.
• Simplified Installation: Standard OEM part 100110701 specifications allow for rapid "swap-and-go" restoration of heating cycles.

Common Questions About the 100110701

How do I test the 100110701 flame rod?
To verify performance, set your multimeter to the microamp (µA) scale and connect it in series between the flame sensor and the control module. A healthy signal typically registers between 2 and 6 µA while the burner is active.

Can I clean this flame rod instead of replacing it?
While light carbon can sometimes be removed with very fine steel wool, cracks in the ceramic insulator or significant metal pitting require immediate replacement of the 100110701 Flame Rod to prevent grounding issues.

What causes a flame rod to fail in A.O. Smith units?
Failure is often caused by flame rectification loss due to high-altitude oxidation, moisture in the combustion air, or internal fractures in the ceramic insulation. Use this genuine OEM part to ensure your HVAC/R system remains code-compliant.
