Mounted on the heat-exchanger bulkhead, it senses supply-air temperature and shuts off the gas valve if the furnace exceeds its safe operating range, protecting the heat exchanger and cabinet from heat damage. This auto-reset control restores operation once temperatures return to normal.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart number: 20162904\u003c\/li\u003e\n\u003cli\u003ePart type: Primary limit temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: High-limit overtemperature safety cutout\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMEH800603BXAA gas furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis OEM control is factory-calibrated to the precise trip point Goodman specifies for the AMEH800603BXAA heat exchanger and blower profile. Aftermarket limit controls with mismatched trip temperatures cause nuisance shutdowns during normal heating cycles or fail to protect the unit under fault conditions.
