Mounted on the blower compartment, it de-energizes the furnace whenever the access panel is removed — preventing the burners and blower from running with the door off. A failed door switch is a common cause of a furnace that won't start at all.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Normally-open door interlock (SPST)\u003c\/li\u003e\n\u003cli\u003eFunction: Cuts 120V power when blower door is removed\u003c\/li\u003e\n\u003cli\u003eActuation: Plunger \/ lever, closes when door is seated\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GUS075-3 furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370819\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4 in. quick-connect\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch matches the exact plunger height and mounting bracket of the GUS075-3 cabinet, so the door seats and actuates reliably.
