Mounted on the heat exchanger or burner box, it monitors plenum temperature and opens the control circuit if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. When it trips, the burners shut down while the blower continues cooling the exchanger. If your furnace short-cycles on heat or fails to fire, a faulty limit switch is a common cause.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10728342\u003c\/li\u003e\n\u003cli\u003eComponent: High-limit \/ temperature safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Normally-closed thermal cutoff, opens on overheat\u003c\/li\u003e\n\u003cli\u003eCompatible Model: WGGE4324A045MAB\u003c\/li\u003e\n\u003cli\u003eApplication: Gas furnace overheat protection\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eEach limit switch is calibrated to a specific trip temperature and physical mount. The genuine Goodman 10728342 opens at the factory-specified setpoint, giving reliable overheat protection without nuisance trips. Generic switches with the wrong rating can either shut the furnace down prematurely or fail to protect the heat exchanger.

If the new switch keeps tripping, check the filter, blower, and ductwork for airflow restriction before assuming a part fault.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058247352691,"sku":"GOODMAN-14599","price":14.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-auto-reset-limit-switch-for-wgge4324a045mab-10728342","provider":"National HVAC Parts","version":"1.0","type":"link"}
