Kenmore Microwave 721.80002400 (72180002400, 721 80002400) Parts

This microwave thermostat is the safety control that monitors temperature and opens the circuit if overheating is detected, protecting internal components. Replace it if your oven is dead, loses heat, or shuts off mid-cycle due to a failed thermostat. What it does:

• Monitors temperature and interrupts power when overheating occurs to help prevent damage
• Helps protect internal components and wiring from excessive heat
• Failure can cause: no power, shuts off during or shortly after starting, or runs but does not heat
• Replacing a failed thermostat helps restore normal operation and safety protections

• 1 thermostat

• Unplug the appliance; microwaves contain high-voltage components that can retain a lethal charge even when unplugged
• Remove the outer cover to access the thermostat; location varies by model
• Move wires one at a time to the new thermostat and mount it firmly against the mating surface for proper heat sensing
• Reassemble, restore power, and test operation

A high-voltage capacitor for the appliance's high-voltage circuit that stores and releases electrical energy to support proper heating operation. Replacing a failing capacitor can restore consistent heating and prevent related electrical faults. What it does:

• Stores and delivers high-voltage energy used by the magnetron/ high-voltage assembly to generate heat.
• Failure may cause no-heat or weak-heat conditions in the oven.
• Faulty capacitors can contribute to arcing, loud humming, or blown high-voltage fuses.
• Works as part of the HV circuit; not a user-serviceable low-voltage control.

• High-voltage components can hold a dangerous charge—disconnect power and discharge the capacitor before servicing.
• Use insulated tools and avoid touching terminals; verify proper operation with appropriate test equipment.

This is a truss-head tapping screw used to secure trim, panels, and small assemblies on compatible LG appliances. It provides a low-profile, wide-bearing head that helps hold parts flush and resist pull-through. What it does:

• Fastens plastic and sheet-metal components where a self-tapping thread is needed
• Truss head spreads load to prevent damage to soft or thin materials
• Helps secure control panels, brackets, or trim pieces that require a low-profile head
• Common replacement when original mounting screws are missing, stripped, or corroded

• One truss-head tapping screw

• Use the correct screwdriver bit and moderate torque to avoid stripping the screw or workpiece
• Start threading straight and let the screw form threads without forcing at an angle
• Disconnect power and follow appliance-specific service safety procedures before working internally
• Replace any damaged mating threads or clips for a secure fit

This replacement mounting screw secures panels and small appliance components to restore proper fit and prevent vibration or loose parts. A simple, direct replacement when the original fastener is missing or damaged. What it does:

• Secures panels, brackets, or small assemblies to keep parts aligned
• Stops rattling or vibration caused by loose or missing screws
• Restores normal fit where a stripped or corroded screw failed
• Matches the OEM fastener form for a correct, long-lasting fit

• Unplug the appliance or disconnect power before servicing
• Use the correct driver to avoid stripping the head
• Thread carefully and do not overtighten to prevent damage to threads or housing

Inner plastic door film covers the holes in the inner door frame.

This replacement lamp assembly restores interior illumination so you can see the appliance cavity clearly and safely. It fits the original mounting and electrical connections for a direct swap. What it does

• Replaces a burned-out, flickering, or dim interior lamp so you can inspect food and parts easily
• Provides the correct shape and connector to match the appliance's original lamp location and mounting
• Helps eliminate intermittent lighting caused by a damaged lamp or failed lamp connection
• Restores normal light output for safe loading and unloading

• Disconnect power to the appliance before starting any repair
• Allow the appliance and old lamp to cool completely before handling
• Handle the lamp by its base or use gloves to avoid oil contamination on the bulb
• Follow the appliance's service manual or OEM diagram for correct removal and installation
