Goodman B1370819 Blower Door Safety Switch

The B1370819 is a genuine OEM blower door interlock switch for the Goodman/Amana ADV81155CXBB gas furnace and related models. This normally-open safety switch de-energizes the furnace whenever the blower access panel is removed, protecting technicians and homeowners from live electrical components and a running blower during service. A furnace that won't start after a filter change or that runs only when the door is pressed usually has a failed or misaligned door switch.

Specifications

Type: SPST plunger interlock switch (normally open until panel closes)
Function: Cuts 24V/line power when blower door is open
Fits: Goodman & Amana furnaces including ADV81155CXBB
Mounting: Bracket-mounted, factory plunger height
Connections: Quick-connect spade terminals

OEM vs. Generic

The OEM B1370819 includes the correct bracket and plunger travel so the door closes fully and reliably makes contact. Generic push-button substitutes often sit at the wrong height, causing intermittent no-heat calls. OEM guarantees proper fit and consistent interlock operation.

Installation Difficulty

Easy (DIY-friendly, ~15–20 minutes). Disconnect power, unscrew the switch bracket, swap the two wire leads onto the new switch, and remount. Verify the panel depresses the plunger fully when reinstalled.
