Description
The Amana-Goodman B1370253 Stack Switch W/ Sheath is a temperature-activated control component used in heating equipment within HVAC systems. Its rating indicates an operating range where the circuit opens at 140F and closes after the temperature drops approximately 30F, managing heat-based electrical switching. It is commonly applied in gas furnace assemblies to monitor stack temperature near the heat exchanger. This switching action supports burner control and blower sequencing, coordinate safe operation of the heating cycle through temperature-responsive circuit management inside the furnace control structure.
