The Goodman B1370820 is a genuine OEM blower-door interlock safety switch, pre-assembled with its wire harness, for the AMV80703BXA furnace and compatible Goodman/Amana models. This normally-open switch cuts power to the furnace whenever the blower access panel is removed, protecting the technician from live electrical components and the spinning blower wheel. If the door switch fails open or is not depressed, the furnace will appear completely dead — no display, no blower, no ignition.

  • Type: normally-open door interlock (single-pole)
  • Includes: factory wire harness / leads
  • Function: de-energizes furnace when blower panel is open
  • OEM part number: B1370820
  • Fits: AMV80703BXA and compatible Goodman & Amana furnaces

OEM vs. Generic: The OEM B1370820 ships with the correct plunger travel, bracket, and pre-terminated harness for a plug-and-play fit. Generic door switches often require splicing and may not align with the panel actuator, risking a switch that never closes and a furnace that won't power up.

Install difficulty: Moderate (2.5/5). Remove the blower panel, unscrew the switch bracket, disconnect the harness, and install the replacement with its leads routed to the original connection points. Shut off power at the disconnect before servicing.
