The Goodman B1370820 Door Interlock Switch is a genuine OEM blower-door safety switch, supplied with wire leads for the GMNTE080-4 gas furnace. Mounted at the blower access panel, this normally-open interlock cuts power to the furnace whenever the door is removed, preventing operation with the blower compartment exposed. It is a required safety device that also disables the unit during service.

Specifications

Type: Blower door interlock / safety switch
Configuration: Normally open, actuated by door plunger
Wiring: Pre-attached wire leads included
OEM part number: B1370820
Compatible model: Goodman GMNTE080-4 furnace
Brand: Goodman (OEM)

OEM vs. Generic

The OEM Goodman B1370820 arrives with correct lead length, connectors, and plunger geometry for a true plug-and-play fit — no splicing guesswork. Our generic equivalent provides the same interlock function and included leads at a lower price for out-of-warranty repairs. Both are UL-recognized safety switches.

Installation Difficulty

Easy (1/5). Disconnect power, unplug or splice the two leads to the existing harness, and snap or screw the switch into its bracket so the door plunger actuates it. No special tools required. Test that the furnace de-energizes when the blower door is opened.
