Amana-Goodman 10728319 Auto Limit Switch 130-170°F

Amana-Goodman 10728319 Auto Limit Switch 130-170F is a temperature safety control to monitor heat levels and regulate furnace operation within a defined range. It operates through a temperature-responsive mechanism that reacts to rising or falling air temperatures opening or closing the electrical circuit when limits are reached to prevent overheating. It is mounted on the furnace heat exchanger or air discharge section during servicing or assembly to provide accurate thermal protection. Once operating, it safeguards internal components, controls cycling behavior, and supports controlled condition during abnormal temperature rise in HVAC systems.
