This normally-closed thermal switch opens the control circuit when it senses an overheat condition, shutting the burners down to protect the heat exchanger and surrounding components. A failed auxiliary limit is a common cause of intermittent no-heat lockouts and short-cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 120°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Auxiliary \/ rollout overheat protection\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed (opens on rise)\u003c\/li\u003e\n\u003cli\u003eMounting: OEM bracket \/ snap-disc style\u003c\/li\u003e\n\u003cli\u003eCompatibility: AMH80703ANAB and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM B1370155\u003c\/strong\u003e is calibrated to the exact factory trip point, guaranteeing correct safety operation and preserving your equipment warranty.
