The Goodman 10690402S Interlock Door Switch is a genuine OEM blower-compartment safety cutoff for the AMEC960803BNAB gas furnace. It cuts power to the furnace whenever the blower access door is removed, preventing operation with the panel off and satisfying required safety interlocks.
The OEM Goodman switch matches the original plunger travel and bracket position, so the door reliably actuates it every time. Generic substitutes often sit at the wrong depth, leaving the furnace dead even with the door on. OEM guarantees correct actuation and a code-compliant interlock.
Easy (1/5) — Disconnect power, unclip the two wires, remove one or two screws, and install the replacement. A quick 10-minute job with a screwdriver.
