The Goodman B1370819 Door Interlock Switch is the genuine OEM blower-compartment safety switch for the ADV81155CXA furnace and compatible Goodman/Amana models. This normally-open switch closes only when the blower access panel is properly seated, allowing 120V power to reach the control board. Remove the door and the furnace safely de-energizes — protecting service technicians and preventing operation with the cabinet open.

Specifications

Part Number: B1370819
Function: Blower-door safety interlock
Type: SPST, plunger-actuated, normally open
Voltage: 120V line-voltage circuit
Brand: Goodman OEM

OEM vs. Generic

A worn or stuck door switch is a common cause of a totally dead furnace. The OEM B1370819 offers the correct plunger travel, contact rating, and mounting tabs so the panel actuates it reliably. Generic switches may not align with the factory bracket, leading to intermittent no-heat calls. OEM fit means the interlock works exactly as designed.

Installation Difficulty

Easy (1.5/5). Unscrew the switch from its bracket, transfer the two wire leads, and remount so the door plunger depresses it fully. Roughly 15 minutes with power off. Confirm the panel seats against the plunger before restoring power.
