Mounted on the heat exchanger\/blower deck, this control continuously monitors supply-air temperature and shuts off the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. Its factory-set trip point protects the heat exchanger and prevents dangerous overheating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (temperature-sensing bimetal)\u003c\/li\u003e\n\u003cli\u003eFunction: Supply-air overheat cutout\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GKS90453BXAC and GKS90-series furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM\u003c\/strong\u003e control is pre-calibrated to Goodman's exact trip temperature and matches the mounting bracket and probe length for this cabinet — essential for a safety device.
