Kenmore Microwave 721.80522500 (72180522500, 721 80522500) Parts

This truss head tapping screw secures panels, brackets, and covers in your appliance. Replacing a missing or damaged fastener restores a snug fit, reduces vibration, and helps keep components properly aligned for reliable performance.

• Provides low-profile holding power; wide truss head helps secure thin panels and trim
• Replaces lost, stripped, or corroded screws at the original mounting points
• Helps eliminate rattling, vibration, or loose handles/covers
• Addresses situations where a screw will not tighten or backs out during use

• Disconnect power; shut off water/gas if applicable before servicing
• Align parts and hand-start threads to avoid cross-threading
• Tighten until snug; do not overtighten to prevent stripping
• If the receiving hole is damaged, for repair before installing the new screw

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 thermostat controls oven/dryer temperature by opening or closing its contacts as the appliance reaches set temperatures, helping maintain safe and consistent operation. Replaces a worn or failed thermostat to restore proper temperature regulation. What it does:

• Senses temperature and interrupts heating when limits are reached to prevent overheating
• Re-establishes heating when temperature falls, maintaining normal cycle performance
• Commonly installed when an appliance won't heat, overheats, or cycles erratically
• Works as a direct replacement for the OEM thermostat designed for compatible LG units

• One thermostat

• Disconnect power to the appliance before starting any repair to avoid shock or injury
• Note wire locations or take a photo before removing wiring; reconnect wires to the same terminals
• Use a multimeter to verify thermostat continuity and correct operation before and after replacement

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 door frame assembly replaces the appliance's outer door trim and support to restore proper door fit and protect the inner door components. Ideal when the door frame is cracked, bent, or no longer secures the door evenly. What it does:

• Restores the outer door trim and structural support so the door closes and latches properly.
• Protects the door glass and inner components from impact and moisture intrusion.
• Helps eliminate gaps or misalignment that can cause rattling, air leaks, or difficulty closing the door.
• Matches the OEM form for a direct replacement when the original frame is damaged.

• Disconnect power and unplug the appliance before starting any repair.
• Remove the existing door trim/frame by loosening the retaining screws or clips; handle any glass carefully.
• Check door alignment and seal after installation; adjust hinge or strike as needed for proper fit.
• If the assembly has bonded or sealed components, consider replacing any associated gasket or fasteners if damaged.

The Door Latch Housing and Interlock Switch Assembly is an OEM replacement part for LG microwaves. It consists of the protective door latch housing casing along with the two-door switches and interlock switch.

The interlock switch prevents microwave energy from being generated inside the oven when the door is open. It shuts off all power once a faulty seal is detected between the door and cavity.

Symptoms of issues can include:

• Microwave failing to turn on or cook with the door open
• Sparking or arcing seen near the door seal or frame
• Error codes displayed related to interlock detection faults

Compatible models include some GE, Kenmore, and Samsung units using matching door designs sourced from LG.
