Parts for Kenmore 721.66222011 (72166222011, 721 66222011): Latch Board Parts

This is a replacement screw used to secure appliance components and panels. It restores proper fastening where a stripped, missing, or damaged screw causes loose parts or rattling. What it does:

• Fastens panels, trim, or internal components to maintain structural fit
• Helps stop vibration-related noise from loose assemblies
• Replaces missing or corroded screws that prevent proper closures
• Restores secure mounting after repairs or disassembly

• Use the correct screwdriver or bit to avoid stripping the head
• Tighten until snug—do not over-torque to prevent thread damage
• Keep small parts away from children and pets
• Disconnect power or water before accessing internal parts

This door interlock micro switch is part of the microwave's latch assembly. It detects when the door is fully closed so the oven only runs when latched, helping restore safe, consistent start/stop operation.

• Senses door-latch position within the interlock assembly
• Cuts power when the door opens; permits operation when fully closed
• Helps resolve "won't start" complaints or stopping when the door is jostled
• Often fixes the need to press or lift the door to keep the unit running

• Unplug the microwave before servicing; high-voltage components can retain a dangerous charge.
• Access the interlock/latch bracket behind the control panel; note switch orientation and terminal labels (COM, NO/NC).
• Transfer wires to the new switch, secure it in the bracket, and ensure the actuator aligns with the door latch.
• Reassemble and test with a cup of water to ensure proper start/stop operation.
