This premium Goodman Primary Limit Switch (L170F) is a critical safety component designed for residential gas furnaces and forced-air heating systems. Operating as a high-limit control, this fan disc switch monitors the temperature of the heat exchanger to prevent the appliance from overheating. Specifically calibrated to open at 170 degrees Fahrenheit, the switch automatically interrupts the electrical circuit to the gas valve if temperatures exceed safe operating limits, protecting your home and equipment from thermal damage. If your furnace is short-cycling, shutting down prematurely, or the blower fan is running continuously, a faulty or tripped limit control may be the issue. This replacement part ensures your HVAC system maintains optimal safety standards and efficient performance during the heating season.
