The Goodman 10690402S Interlock Door Switch is a genuine OEM blower-door safety switch for the Amana AMES960603BNAA gas furnace. This normally-open switch cuts power to the control board and blower whenever the access panel is removed, protecting the technician and preventing operation with the cabinet open. If your furnace is completely dead only when the door is on, a failed interlock switch is a likely culprit.
This OEM Goodman/Amana switch matches the exact plunger travel and mounting bracket of your furnace. Universal door switches often have a different actuation length and mounting pattern, leading to a furnace that reads the door as open even when it's closed.
Easy (1/5). Two spade terminals and a single mounting screw or snap-in bracket — about 10 minutes. Always shut off power at the breaker before removing the blower door and servicing.
