This thermal safety cutout monitors heat-exchanger temperature and shuts off the gas valve if the furnace overheats — protecting against blocked airflow, a failed blower, or a dirty filter. A limit switch that has failed open causes no-heat calls; one stuck closed defeats a critical safety function.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Snap-disc high-limit (auto-reset)\u003c\/li\u003e\n\u003cli\u003eOpen temperature: 180°F\u003c\/li\u003e\n\u003cli\u003eTerminals: Dual spade quick-connect\u003c\/li\u003e\n\u003cli\u003eMount: Flange with mounting screws\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 1370901S\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMP075-4\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 1370901S\u003c\/strong\u003e is calibrated to Goodman's exact 180°F trip point and correct disc placement. Because this is a safety device, an off-spec generic that trips too high or too low can either nuisance-shut the furnace or fail to protect the heat exchanger. OEM is strongly recommended for any limit control.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — turn off power and gas, note the two wire positions, remove the mounting screws, and install the replacement in the same location.
