Lochinvar & A.O. Smith 100112696 Limit
The Lochinvar & A.O. Smith 100112696 High Ambient Limit is a critical safety component designed for high-efficiency commercial boilers and water heaters. Engineered to monitor exhaust manifold temperatures, this thermal limit switch prevents equipment damage by interrupting the burner circuit if temperatures exceed safe operational parameters. This OEM part is a direct replacement for Lochinvar part number LIM2401 and is commonly utilized in Knight (KB, KH) and Armor (AW) series units. As a normally closed (NC) switch, it ensures system integrity by sensing ambient heat levels within the cabinet. Replacing a tripped or degraded 100112696 limit is essential for restoring modulating condensing boiler functionality and preventing nuisance fault codes. Proper electrical continuity testing is recommended during diagnostic procedures to confirm failure before installation. This sensor ensures precise thermal protection for sensitive internal electronics and combustion components in demanding mechanical room environments.
- Precise Thermal Calibration: Designed to actuate at specific high-limit thresholds to prevent heat exchanger and cabinet overheating.
- OEM Compatibility: Standardized fit for Lochinvar Knight and A.O. Smith commercial water heating systems.
- Robust Construction: Built to withstand the high-cycle demands of commercial HVACR applications.
- Enhanced Safety: Acts as a fail-safe to prevent thermal runaway and potential component melting.
What causes the 100112696 high ambient limit to trip?
This limit typically trips due to insufficient ventilation, a blocked flue, or internal cabinet heat buildup caused by a compromised combustion seal.
Is the 100112696 limit a manual or automatic reset?
This specific high ambient limit is generally designed as a safety device that requires manual inspection of the system before the unit can be returned to service.
Can I bypass this limit for testing purposes?
While technicians may use a temporary jumper for diagnostic troubleshooting, the limit must be installed for safe operation to prevent permanent equipment damage.
