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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOEM replacement limit switch for confirmed INTERNATIONAL COMFORT PRODUCTS furnace models\u003c\/li\u003e\n  \u003cli\u003eOpens control circuit on overtemperature condition to protect heat exchanger and burner assembly\u003c\/li\u003e\n  \u003cli\u003eMounts in any orientation for flexible installation in restricted cabinet spaces\u003c\/li\u003e\n  \u003cli\u003eCompact 1 inch x 1 inch x 1 inch form factor matches OEM footprint for direct swap\u003c\/li\u003e\n  \u003cli\u003eConsistent actuation response supports reliable cycle control and reduces nuisance lockouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConfirmed compatible with INTERNATIONAL COMFORT PRODUCTS furnace models N80VSL0902420A1, N80ESL0451712A1, and N80ESN0451712A1.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed HVAC technician should perform this replacement.
