Lochinvar & A.O. Smith 100208558 Sensor
The Lochinvar & A.O. Smith 100208558 Sensor is a critical premix gas/air arm sensor designed for high-efficiency combustion systems. This OEM replacement part is engineered to monitor the air-fuel ratio within the burner assembly, ensuring precise modulation and optimal thermal efficiency. As a high limit outlet sensor, it provides real-time data to the control board to prevent overheating and maintain safe boiler operation. Constructed from stainless steel for long-term durability in high-heat environments, the 100208558 is frequently utilized in Lochinvar Shield water heaters (models SNR126-065 through SNR501-125) and Crest boilers. A failing 100208558 sensor can lead to erratic flame signals, ignition failure, or combustion instability. Integrating this genuine Lochinvar combustion sensor restores system reliability and helps contractors meet emissions standards by maintaining the correct gas-to-air mixture during the premix phase.
Key Benefits- Precise Combustion Control: Accurately monitors the premix gas/air arm to ensure the stoichiometric ratio is maintained for peak efficiency.
- Engineered Compatibility: Direct OEM replacement part for diverse Lochinvar and A.O. Smith series, including Shield and Crest units.
- Rugged Construction: Features a stainless steel probe designed to withstand rapid temperature fluctuations and corrosive flue gases.
- Safety Integration: Functions as a high limit sensor to provide essential diagnostic feedback and prevent system overheating.
What are the signs of a faulty 100208558 sensor?
Technicians typically observe "no flame" lockout codes, inconsistent burner modulation, or soot buildup due to an improper air-fuel ratio. Replacing the 100208558 sensor often resolves these combustion-related errors.
Is the 100208558 compatible with older TST20014 models?
Yes, the Lochinvar 100208558 is the current manufacturer-authorized replacement for legacy part numbers TST20014, TST20014K, and 100170543.
Does this sensor affect boiler emissions?
Absolutely. By providing the control board with accurate data regarding the premix gas mixture, it allows the system to minimize NOX emissions and maintain optimal performance.
