The Goodman B1370819 is a factory-original blower-door interlock switch for DDS80703AXA gas furnaces. This safety device cuts electrical power to the furnace whenever the blower access panel is removed, protecting technicians and homeowners from live components and rotating parts during service.

Specifications

Action: Normally Open plunger; closes when door is installed
Function: Power cutoff safety interlock
Fit: Goodman/Amana furnaces including DDS80703AXA

OEM vs. Generic

The OEM switch matches Goodman's exact plunger length and mounting footprint so the door engages it properly — critical, since a mis-seated switch leaves the furnace dead. Generic substitutes may need bracket adaptation. For a trouble-free fit, OEM is recommended.

Install Difficulty

Easy (2/5) — Disconnect power, unclip the old switch, transfer two leads, and snap the new one into the mounting slot. A quick repair for a qualified HVAC technician.
