Icp 1320438 Limit Switch GUF075A008 Replacement

Product Description

The INTERNATIONAL COMFORT PRODUCTS 1320438 is a replacement limit switch designed for gas furnace applications. A limit switch is a safety control device that monitors heat exchanger temperature and shuts off the burner if the furnace overheats, preventing equipment damage and protecting building occupants. This switch is an OEM-replacement component installed by licensed HVAC technicians during preventive maintenance or fault diagnosis. It is a direct replacement for several superseded part numbers, making it a reliable sourcing option when servicing units in the field.

This limit switch is specified for use with the GUF075A008 gas furnace. It is suited for residential forced-air heating systems where the original limit switch has failed, tripped non-resettably, or is being replaced as part of a heat exchanger inspection and service call. Technicians servicing Comfortmaker-branded equipment will find this part directly applicable to that platform.
