This safety switch continuously monitors heat-exchanger temperature and opens the circuit to shut off the burners if the furnace overheats — protecting against restricted airflow, a failed blower, or a plugged filter. A tripped or failed limit control is a common cause of short-cycling and no-heat calls.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eFunction: Primary high-limit \/ auto-reset temperature control\u003c\/li\u003e\n\u003cli\u003eType: Bimetallic snap-disc safety switch\u003c\/li\u003e\n\u003cli\u003eFits: Goodman AKSS920453BXAA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eRole: Cuts burner power on over-temperature\u003c\/li\u003e\n\u003cli\u003eReplacement: Direct-fit OEM component\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162904 is calibrated to the exact trip and reset temperatures Goodman specifies for this furnace's heat exchanger. Generic limit switches often use approximate temperature ratings, which can allow dangerous overheating or cause nuisance trips. Because this is a life-safety device, the genuine OEM part is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy to Moderate\u003c\/strong\u003e — The switch is typically mounted with two screws and two spade terminals.
