This switch monitors furnace temperature and opens the circuit if the unit overheats — protecting the heat exchanger and preventing dangerous conditions. As a \u003cstrong\u003emanual reset\u003c\/strong\u003e device, it stays open after a trip and must be reset by hand, which alerts homeowners that an overheat event occurred and should be investigated (often a dirty filter or blocked airflow).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens on overtemperature to shut off gas\/burners\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual (push-button)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 10123539\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMP100-4 furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a \u003cstrong\u003ecombustion safety component\u003c\/strong\u003e, an exact trip temperature is critical. This \u003cstrong\u003egenuine OEM Goodman switch\u003c\/strong\u003e is calibrated to Goodman's factory limit setpoint. Generic switches may trip at the wrong temperature — too early causes nuisance shutdowns, too late defeats the safety function. Always use OEM for limit and rollout controls.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty: Easy\u003c\/h3\u003e\u003cp\u003eRated \u003cstrong\u003eEasy (2\/5)\u003c\/strong\u003e. Replacement takes about 15 minutes: shut off power and gas, disconnect the two spade terminals, remove the mounting screws, and install the new switch in the same location. Do not bypass a tripped limit switch. If the switch keeps tripping, have a \u003cstrong\u003elicensed technician\u003c\/strong\u003e diagnose the underlying airflow or combustion issue.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058136727923,"sku":"GOODMAN-11883","price":6.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-manual-reset-limit-switch-for-gmp100-4-10123539","provider":"National HVAC Parts","version":"1.0","type":"link"}
