International Comfort Products 1190610 Limit Switch

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1190610 is an OEM limit switch designed to protect gas furnace heat exchangers and related components from overtemperature conditions. When supply air temperatures exceed a safe threshold, the limit switch opens the control circuit and shuts down the burner, preventing heat exchanger damage and reducing fire risk. Rated for any mounting orientation, this switch drops directly into the OEM location without modification. Licensed HVAC technicians install this part as part of routine safety-system maintenance or when diagnosing furnaces that short-cycle or lock out on high-limit faults.

This limit switch is suited for residential gas furnace applications where OEM-spec safety controls are required. It is confirmed compatible with the following model numbers: N80VSL0902420A1, N80ESL0451712A1, and N80ESN0451712A1. The any-orientation mount design gives installers flexibility when working in tight furnace cabinets where access can be restricted.
