The Goodman B1370819 is a genuine OEM blower-door interlock safety switch for the ADS81155CXA furnace and many compatible Goodman/Amana models. This normally-open plunger switch de-energizes the furnace whenever the blower access panel is removed, preventing operation with the door off and protecting service technicians and homeowners.

Specifications

  • Type: SPST plunger door-interlock switch
  • Function: Cuts control power when blower door is open
  • OEM part number: B1370819
  • Terminals: 1/4" quick-connect
  • Equipment: Goodman / Amana gas furnaces

OEM vs. Generic

The OEM switch matches the original plunger height and mounting footprint, so the door reliably actuates it on reassembly. Generic universal switches may need shimming or bending of the bracket and can fail to make contact, leaving the furnace dead. OEM is the no-fuss choice.

Installation Difficulty

Easy — clips or screws into the blower compartment with two wires. Disconnect power before replacing. A 5–10 minute job for most DIYers.
