This bi-metal snap-disc control senses supply-air\/heat-exchanger temperature and opens the heating circuit if the furnace exceeds its safe operating limit — protecting the heat exchanger from cracking due to restricted airflow, a dirty filter, or a failed blower. It is a primary safety device that works alongside the rollout and auxiliary limits on this platform.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eGenuine Goodman\/Amana OEM limit control\u003c\/li\u003e\n\u003cli\u003eSnap-disc bi-metal thermal switch, normally closed\u003c\/li\u003e\n\u003cli\u003eOpens the gas\/heat circuit on overheat, closes when temperature normalizes\u003c\/li\u003e\n\u003cli\u003eFactory-calibrated trip point for this cabinet\u003c\/li\u003e\n\u003cli\u003eDirect-fit for WGGE4537A090MAA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe trip and reset temperatures of a limit switch must match the furnace it protects. A generic switch with the wrong calibration will either nuisance-trip in normal operation or allow the heat exchanger to overheat. The OEM 10728343 is set to Goodman's factory spec, giving you correct, reliable protection and clean cut-in\/cut-out behavior.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy\u003c\/strong\u003e — usually two mounting screws and two spade connectors, mounted in the blower or supply-air path. Plan 15–20 minutes. Disconnect power before servicing. If the limit continues to trip after replacement, correct the airflow restriction — never jumper or bypass a limit switch.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eCompatible model:\u003c\/em\u003e WGGE4537A090MAA.
