This safety switch cuts power to the furnace whenever the blower access panel is removed, protecting service technicians from live wiring and spinning blower blades. A common no-heat \/ dead-furnace complaint traces back to a broken, stuck, or misaligned door switch — the furnace simply won't run with the panel off (or with a failed switch on).\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Plunger \/ push-button door interlock\u003c\/li\u003e\n\u003cli\u003eConfiguration: Line-voltage cutoff, normally open (closes when door is installed)\u003c\/li\u003e\n\u003cli\u003eFunction: De-energizes furnace when blower panel is removed\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GUN050-2B furnace\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: B1370819\u003c\/li\u003e\n\u003cli\u003eConnection: Spade terminals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370819\u003c\/strong\u003e matches the exact plunger length, bracket, and mounting point so the panel actuates it correctly — a mismatched switch may not depress fully and leave the furnace dead.

Tip: to test with the door off, do not permanently jumper the switch — only depress it briefly for diagnostics. About 10 minutes with a nut driver.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058188173683,"sku":"GOODMAN-13119","price":22.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-blower-door-safety-switch-for-gun050-2b-b1370819","provider":"National HVAC Parts","version":"1.0","type":"link"}
