International Comfort Products 1186925 Limit Switch

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1186925 is a genuine OEM replacement limit switch and thermostat designed to protect gas furnace heat exchangers from overheating conditions. When supply air temperature exceeds the rated setpoint, the limit switch interrupts the burner circuit to prevent heat exchanger damage and unsafe operation. Once the system returns to a safe temperature, the switch resets and normal operation resumes. This is a direct OEM replacement part, meaning it matches the original calibration, form factor, and electrical ratings of the factory-installed component. Licensed HVAC technicians install this part as part of routine furnace maintenance or in response to nuisance lockout diagnostics.

This limit switch is suited for residential gas furnace applications where the original component has failed, drifted out of calibration, or been damaged. It is appropriate for installations where the furnace is exhibiting high-limit trips, short cycling, or burner lockout conditions traced to the limit circuit. The any-orientation mount type allows flexible positioning during reinstallation without affecting performance or setpoint accuracy.
