The Goodman B1370820 Door Switch is a genuine OEM blower-compartment interlock switch supplied with a pre-wired lead harness for fast installation on GMNTE060-3 gas furnaces and compatible Goodman/Amana models. This safety switch cuts power to the furnace whenever the blower access panel is removed, preventing operation with the door open and protecting technicians and homeowners during service.
The OEM B1370820 ships complete with the correct connector and lead length, so it plugs into the existing harness without splicing. Generic plunger switches often require cutting and crimping and may not align with the door striker, leading to intermittent no-power faults. The included wiring makes the OEM part the reliable choice.
Easy (1–2/5). Disconnect power, unclip the old switch from its bracket, unplug the harness, and snap in the replacement. Because the leads are pre-terminated, no wire crimping is needed — typically a 15–20 minute repair.
