The Goodman B1370819 Door Switch is a genuine OEM blower-door interlock that de-energizes your DDS80453AXA furnace whenever the blower access panel is removed. This plunger-actuated safety switch prevents the burners and blower from operating with the cabinet open, protecting both the technician and the equipment.

Specifications

Part number: B1370819
Function: Blower-door interlock safety switch
Actuation: Spring-loaded plunger (normally open)
Brand: Goodman / Amana

OEM vs. Generic

This genuine Goodman OEM switch matches the original plunger length, mounting bracket, and terminal layout, so it seats correctly against the door and makes reliable contact. Generic substitutes often have the wrong plunger throw, leaving the furnace dead or unsafely bypassed. Choose OEM for a guaranteed fit.

Installation Difficulty

Easy — unplug the two spade terminals, remove the mounting screws, and reverse for the new switch. Disconnect power at the breaker first. Typical replacement takes 15–20 minutes with a screwdriver and pliers.
