The 10690402S is a genuine OEM door interlock safety switch for the Goodman VMES960603BNAA gas furnace and compatible Goodman/Amana models. This switch cuts power to the furnace whenever the blower access panel is removed, preventing operation with the door open — a required safety interlock on modern high-efficiency furnaces.
OEM ensures the plunger length, actuation force, and electrical rating match the factory spec so the door seats and the switch closes reliably. Generic switches are cheaper but often differ in plunger geometry, leading to intermittent no-heat calls. For a code-required safety part, choose OEM.
Easy (1/5). Snap-in or single-screw mount with two spade terminals. Power off before replacing; confirm the plunger is depressed when the door is closed.
