Goodman B1370819 Blower Door Safety Switch

The B1370819 is the genuine OEM blower-compartment door interlock switch for Goodman ADV81155CXBA gas furnaces and other compatible Goodman/Amana models. This safety switch de-energizes the furnace whenever the blower access panel is removed, protecting technicians and homeowners from live electrical and moving-blower hazards during service. A failed or stuck door switch is a common cause of a furnace that won't start after a filter change or panel removal.

Specifications

  • Type: SPST normally-open blower door interlock switch
  • Primary fit: Goodman ADV81155CXBA furnace
  • Function: Cuts 24V/line power when blower door is off
  • Mounting: Plunger-actuated, panel-edge mount
  • OEM Part Number: B1370819

OEM vs. Generic

This is a genuine Goodman OEM switch — an exact plunger length and electrical rating match, so the door seats and the interlock trips reliably. Aftermarket universal switches often need bracket modification and can misfire, leaving the furnace dead or unsafe. For a safety-critical interlock, OEM is the recommended choice.

Installation Difficulty

Easy (1/5) — Typically two wire leads and a single mounting screw or clip. Cut power at the breaker, transfer the wires, and snap the switch into place. Most homeowners complete this in under 15 minutes with a screwdriver.
