Icp 1176908 Limit Switch 235 Degrees F

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1176908 is a high-temperature limit switch designed to protect furnace heat exchangers and related components from overheating. When supply air temperature exceeds the rated threshold of 235 degrees F, the switch interrupts power to the burner circuit, preventing thermal damage and potential safety hazards. The switch accepts any mounting orientation, giving technicians flexibility during installation in tight equipment compartments. Licensed HVAC technicians typically install this component as a direct OEM replacement during routine furnace service or after a no-heat diagnostic reveals an open limit condition.

This limit switch is rated for residential gas furnace applications where high-temperature protection is required in the burner or heat exchanger zone. It is an OEM part sourced directly from INTERNATIONAL COMFORT PRODUCTS, making it appropriate for service calls where maintaining factory specifications is required to preserve equipment warranty coverage or support service documentation. Compatible models include N8MSL1352422A3, G8MVL1352422A1, and F8MVL1352422A1.
