International Comfort Products 1185458 Limit Switch L220-20F

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1185458 is a genuine OEM replacement limit switch and thermostat designed for residential gas furnace applications. This component monitors heat exchanger temperature and interrupts furnace operation when temperatures exceed safe thresholds, protecting the heat exchanger and other components from overheating damage. Rated at L220-20F, it opens at 220 degrees F and resets at 20 degrees F below that point. Licensed HVAC technicians install this part as a direct OEM-style replacement to restore proper high-limit protection and return a furnace to safe operation.

This limit switch fits furnace models including the F9MXE0261410A2, N92ESN, and N95ESN series, along with additional compatible units. It is suited for residential gas furnace installations where the original high-limit device has failed or is out of calibration. Replacing a failed limit switch restores the furnace safety circuit, allowing normal heating cycles to resume without nuisance lockouts or uncontrolled high-temperature conditions.
