This plunger-style switch sits on the blower compartment and cuts power to the furnace whenever the blower access door is removed. It prevents the unit from operating with the door open — protecting service technicians and ensuring proper combustion-air sealing. A furnace that is completely dead but has good incoming power is often traced to a stuck, broken, or missing door switch.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1370820\u003c\/li\u003e\n\u003cli\u003eType: Plunger interlock (door) switch, single-pole\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally-open, closes when door is installed\u003c\/li\u003e\n\u003cli\u003eWiring: Pre-attached lead wires with connectors\u003c\/li\u003e\n\u003cli\u003eMount: Snap-in bracket on blower deck\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMPV100-5 and compatible furnace models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1370820 ships with the correct wire harness and connectors already installed, so it plugs in without splicing.
