The Goodman B1370109 Stack Overtemp Limit Switch is a genuine OEM safety control designed for GUN060-3 gas furnaces. This normally-closed thermal limit monitors heat-exchanger and stack temperature, opening the 24V control circuit to shut down the burners if the furnace overheats — protecting the equipment and your home from unsafe operating conditions.

Specifications

Function: Stack / high-limit overtemp cutout
Circuit: Normally closed, opens on rise
Control voltage: 24VAC
Fits: Goodman GUN060-3 furnace
Mounting: Direct OEM replacement

OEM vs. Generic

This is the factory Goodman part (B1370109), calibrated to the exact trip temperature specified for the GUN060-3. Generic aftermarket limits may trip early (nuisance shutdowns) or late (safety risk) if the temperature rating doesn't match. For a safety-critical control, we recommend the OEM part.

Installation Difficulty

Easy (1/5). A two-wire swap that most homeowners can complete in minutes. Always cut power at the breaker before servicing. If the switch has failed repeatedly, have a technician check for airflow restrictions or a cracked heat exchanger.
