This normally-closed thermal switch opens at 120°F to interrupt the ignition or blower circuit when it senses abnormal heat, protecting the heat exchanger and surrounding cabinet from overheating. If your furnace short-cycles, locks out, or trips on a limit fault, a failed auxiliary limit is a common and inexpensive culprit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B1370155\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary (rollout\/high-limit) thermal switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Temperature:\u003c\/strong\u003e 120°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e Automatic reset, normally closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GDS81155CNA (and select Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman Genuine OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eGenuine Goodman OEM\u003c\/strong\u003e switch is calibrated to the exact factory trip point, guaranteeing correct sensing and safe operation.
