Lochinvar & A.O. Smith 100109916 Limit Control 326058-756 High-Thermal Endurance: High-purity silicon carbide

High-Thermal Endurance: High-purity silicon carbide design resists oxidation and thermal shock in demanding high-cycle environments

which minimizes vibration-induced noise and prevents premature wear on the motor shaft

this switch prevents hazardous operation by detecting venting obstructions or inducer failure

it frequently serves as a direct substitute for standing pilot Honeywell controls

which functions as a breather hole to eliminate the need for external vent piping in indoor installations

Lochinvar & A.O. Smith 100109916 Limit Control 326058-756 High-Thermal Endurance: High-purity silicon carbideThe Lochinvar & A. O. Smith 100109916 Dual Limit Control is a critical safety component designed for heavy duty commercial and residential heating systems. This OEM water heater part serves as a high precision manual reset limit switch, engineered to prevent hazardous overheating by interrupting the burner circuit when temperatures exceed the safe operational threshold.
