The Goodman B1370819 is a blower door interlock safety switch designed for the ADV80703BXBA gas furnace and compatible Goodman/Amana models. Mounted at the blower compartment, this normally-open switch closes only when the access panel is properly installed, cutting 120V power to the furnace whenever the door is removed. It protects service technicians and homeowners from live electrical and moving-blower hazards, and a failed switch is a frequent reason a furnace appears completely dead.

Specifications

Type: plunger-actuated door interlock safety switch
Contacts: normally open (closes when door is installed)
Voltage: 120 VAC line interlock
OEM part number: B1370819
Primary fit: Goodman ADV80703BXBA furnace
Equipment type: gas furnace

OEM vs. Generic

The OEM B1370819 matches the exact plunger length and mounting footprint so the panel engages the switch reliably every time. Generic door switches often differ in actuator height, leading to intermittent power or a furnace that won't start with the door on. For a dependable interlock, the genuine Goodman part is recommended.

Install Difficulty

Easy (2/5). Disconnect power, remove the blower panel, unplug the two wire terminals, and unclip or unscrew the switch from its bracket. Install the replacement in the same position, confirm the plunger is depressed when the panel is seated, and verify the furnace powers up only with the door in place.
