The stack switch monitors flue\/vent temperature at the induced-draft or collector box area. If exhaust temperatures climb too high — a sign of a blocked flue, restricted venting, or a combustion problem — the switch opens and shuts the furnace down to prevent overheating and unsafe venting conditions.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Flue\/stack over-temperature protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Normally-closed thermal limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Auto reset on cool-down\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMNTE120-5 furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection:\u003c\/strong\u003e 1\/4 in quick-connect terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This genuine Goodman switch matches the factory trip temperature, bracket, and terminal layout exactly.
