The Goodman B1370155 Auxiliary Limit Switch is a genuine OEM safety component engineered for GDS81155CNA gas furnaces. 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.
