Mounted on the heat-exchanger or blower bulkhead, it continuously monitors supply-air temperature and shuts down the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower. This auto-reset control closes again once the furnace cools, protecting the heat exchanger from cracking and preventing unsafe operating temperatures.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto reset)\u003c\/li\u003e\n\u003cli\u003eContact configuration: Normally closed (SPST), opens on temperature rise\u003c\/li\u003e\n\u003cli\u003eFunction: Burner shutdown on supply-air overheat\u003c\/li\u003e\n\u003cli\u003eTerminals: Quick-connect spade\u003c\/li\u003e\n\u003cli\u003eMount: Bulkhead \/ heat-exchanger location, direct-fit\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana WFD195045S3BAA and compatible models\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\n\u003cp\u003eBecause trip temperature is calibrated to this specific furnace, we strongly recommend the \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e control. A generic limit with the wrong cutout point can allow the heat exchanger to overheat or cause nuisance shutdowns. For a safety-critical part, OEM is the right call.\u003c\/p\u003e\n\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eEasy (2 of 5).\u003c\/strong\u003e Roughly 20 minutes. Turn off gas and electrical power, disconnect the spade terminals, remove the two mounting screws, and install the new control in the same position and orientation. Before resetting a furnace that tripped on limit, correct the underlying airflow problem (replace the filter, check the blower). When in doubt, consult a licensed technician.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058218123635,"sku":"GOODMAN-13909","price":48.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-wfd195045s3baa-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
