The Goodman B1370819 Blower Door Safety Interlock Switch is a genuine OEM replacement engineered for the Goodman ADV80905CXBB gas furnace and other compatible Goodman/Amana models. This normally-open switch is a critical safety device: it interrupts 24V control power the moment the blower access panel is removed, shutting the furnace down so it cannot run with the door open. A failed or stuck door switch is one of the most common reasons a furnace won't ignite.

Part number: B1370819
Function: Blower door safety interlock (power cutoff)
Contact type: Normally open, plunger actuated
Voltage: Low-voltage 24V control circuit
Fits: Goodman ADV80905CXBB and compatible Goodman/Amana furnaces
Material: Molded housing with spring-loaded plunger

OEM vs. Generic: Our genuine Goodman OEM switch matches the factory mounting bracket, plunger travel, and contact rating exactly, so it seats correctly and actuates reliably. Aftermarket switches often have slightly different plunger heights that cause nuisance no-heat calls or fail to make contact when the door is closed.

Install difficulty: Easy — 15 to 20 minutes. Two spade terminals and a single mounting screw. Always shut off power at the breaker before servicing.
