The genuine Goodman B1370820 is the blower door interlock safety switch, supplied with factory wire leads, for GMPN060-3 gas furnaces. This plunger-style switch cuts power to the furnace whenever the blower access panel is removed, preventing operation with the compartment open. A furnace that is completely dead — no inducer, no ignition — is very often a failed or unseated door switch.

Specifications

  • Type: plunger / interlock door safety switch
  • Wiring: pre-attached wire leads (plug-in)
  • Contact: opens circuit when blower door is removed
  • Actuation: pressed closed by the blower access panel
  • Application: Goodman GMPN060-3 gas furnace

OEM vs. Generic

The OEM B1370820 comes prewired with the correct connector and plunger travel to match the GMPN060-3 door panel, so it seats and actuates properly. Generic switches often need wire splicing and may not align with the panel, leading to intermittent power loss. OEM is the reliable, plug-in choice.

Installation Difficulty

Easy (2/5). Shut off power, unclip the old switch from its bracket, unplug the harness, plug in and clip in the new switch, then reinstall the blower door. No splicing required. 10 minutes.
