It continuously senses supply-air temperature and opens the control circuit if the furnace exceeds its safe operating limit, shutting down the burners to protect the heat exchanger. This is a core safety device — a failed or out-of-calibration limit switch can cause short cycling, no-heat conditions, or, if bypassed, unsafe overheating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e High-limit temperature switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens on overtemperature to de-energize burners\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bracket \/ plate mount with spade terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 10728343\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\u003eLimit switches must trip at a precise factory-set temperature to protect the furnace correctly.

Plan on about 15 minutes: turn off power and gas, note and disconnect the terminal wires, unscrew the old switch, and mount the replacement in the identical position.
