This plunger-style safety switch cuts all power to the furnace whenever the blower access panel is removed, preventing the unit from operating with an open cabinet — a critical protection against electric shock and unsafe combustion airflow. A stuck, broken, or missing door switch is a frequent cause of a furnace that appears completely dead: no display, no blower, no ignition, even though power is present at the disconnect.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Normally-open plunger interlock (door safety) switch\u003c\/li\u003e\n\u003cli\u003eFunction: Interrupts line power when blower panel is removed\u003c\/li\u003e\n\u003cli\u003eActuation: Spring-loaded plunger closed by the access door\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana AMSS960402BNAA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10690402S\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 10690402S\u003c\/strong\u003e matches the exact plunger height, bracket, and contact rating so the door reliably closes the circuit every time the panel is secured.
