The Goodman B1370820 Blower Door Safety Switch is a genuine OEM interlock built for the Goodman GSU060-3 gas furnace. Supplied pre-wired with lead harness, this switch cuts power to the furnace whenever the blower access door is removed, protecting service personnel and preventing operation with the cabinet open. A failed door switch is a common reason a furnace will not start after service.

Type: Blower / access door interlock switch

Action: Normally open, closes when door is installed
Compatible Model: Goodman GSU060-3 furnace

OEM vs. Generic

The Goodman OEM assembly arrives with the correct connector and lead length, so it drops in without splicing or crimping. Generic door switches often require you to reuse or modify the original wiring, adding failure points at a safety interlock. OEM is the cleaner, more reliable choice here.

Installation Difficulty

Easy to Moderate (2/5). Typically a single-bracket, plug-in swap. Disconnect power before removing the blower door. Verify the actuator plunger lines up with the door so the interlock seats fully when the panel is reinstalled.
