Lochinvar & A.O. Smith 100111979 Sensor
The Lochinvar & A.O. Smith 100111979 Sensor is a high-precision flame sensor designed for gas-fired boilers and water heaters. As a critical safety component, this replacement flame sensor utilizes flame rectification to monitor the burner constantly. When the control module receives a signal of at least 10 microamps, it confirms a stable pilot or main burner flame, ensuring the gas valve remains energized. If the 100111979 sensor fails to detect ionizing current, the integrated control initiates a safety lockout to prevent hazardous gas accumulation. Common symptoms of a fouled HVAC flame rod include intermittent ignition failure or "B2-70" fault codes on Lochinvar Armor and Knight models. Professionals often encounter carbon buildup or oxidation on the probe, which insulates the sensor and disrupts the DC microamp signal. Replacing a worn or corroded Lochinvar flame detector restores reliable furnace flame detection and prevents nuisance shutdowns during peak demand. This OEM component ensures exact fitment and electrical compatibility across a wide range of A.O. Smith and Lochinvar commercial and residential high-efficiency condensing units.
Key Benefits:
- Precise Flame Rectification: Engineered to provide accurate microamp feedback to the integrated control, preventing false lockouts.
- OEM Compatibility: Direct replacement for Lochinvar & A.O. Smith 100111979, ensuring proper alignment within the burner assembly.
- Enhanced Safety: Acts as an essential safety part by shutting down gas flow immediately if a flame is lost or not established.
- Durable Construction: Built to withstand high-temperature combustion environments for consistent monitoring in condensing boilers.
- System Reliability: Fixes common ignition failure issues related to dirty or oxidized sensors in gas-fired equipment.
Common Questions:
- What causes a B2-70 ignition failure code? This code typically indicates the flame sensor is dirty or failing to send a sufficient signal to the control board.
- Can I clean the 100111979 sensor instead of replacing it? While technicians often use fine steel wool for temporary cleaning, deep oxidation or structural damage to the rod requires a full replacement for reliable operation.
- Is this sensor compatible with all Lochinvar models? It fits many series including Armor and Knight, but always verify your specific model and serial number against the OEM part number before installation.
