The Goodman B1370820 is a genuine OEM blower-door interlock switch, supplied with its factory wire harness, for the Goodman/Amana GMNTE100-4 gas furnace and compatible models. This safety switch cuts power to the furnace whenever the blower access door is removed, preventing the unit from operating with the panel open. A furnace that is completely dead — no ignition, no blower, no control-board activity — is very often caused by a failed or misaligned door switch.

Specifications

Type: Blower-door interlock / safety cutoff switch
Included: Pre-terminated wire harness
Function: Disables furnace when access door is open
OEM Part Number: B1370820
Fits: Goodman GMNTE100-4 and compatible furnaces
Brand: Goodman / Amana OEM

OEM vs. Generic

The OEM B1370820 ships with the correct plunger length, mounting tabs, and factory harness so it lines up with the door and connects without splicing. Generic door switches frequently have a different actuator height or lead configuration, forcing awkward workarounds that compromise the safety interlock. The genuine part restores the furnace exactly as designed.

Installation Difficulty

Easy — Disconnect power, unclip the old switch and harness, and snap the replacement into the same bracket, routing the leads to the original connectors. Confirm the door depresses the plunger fully; the furnace should stay off with the door removed and energize when it is reinstalled.
