Kenmore Microwave 721.88502800 (72188502800, 721 88502800) Parts

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 factory fastener secures appliance panels and components. Use it to replace a missing, stripped, or corroded screw so brackets, covers, and assemblies stay tight and properly aligned, helping reduce vibration and rattling.

• Secures panels, brackets, and internal components in their proper positions
• Replaces missing, worn, or cross-threaded hardware
• Helps eliminate vibration and rattling from loose parts
• Supports proper alignment of covers and assemblies

• Disconnect power to the appliance before servicing; allow any moving parts to stop
• Match this screw to the location shown in your model's parts diagram
• Start threads by hand to avoid cross-threading, then tighten snugly with the correct driver
• Do not overtighten to prevent stripping threads or cracking plastic bosses

This door frame assembly replaces a damaged or cracked outer door frame to restore the washer/dryer door's appearance and structural support. It helps secure the door glass and maintain proper door alignment for safe operation. What it does:

• Replaces a broken, cracked, or warped outer door frame to restore form and function
• Supports and secures the door glass/window to prevent rattling or movement
• Helps maintain correct door alignment so the latch and seal engage properly
• Can reduce drafts, leaks, and vibration caused by a damaged frame

• Disconnect power (and water if applicable) before starting any repair
• Handle glass and frame edges carefully; wear gloves and eye protection
• Retain original screws and mounting hardware unless replacement parts are supplied
• Check door seal/gasket and latch engagement when reinstalling to ensure a proper fit

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 truss head tapping screw secures interior panels and small components on compatible appliances, restoring proper fit and stopping rattles or loose trim. It's a direct hardware replacement for a single mounting point. What it does:

• Fastens panels, brackets, and trim where a low-profile truss head is required
• Replaces missing or stripped screws that cause rattling or loose parts
• Provides a secure hold by forming threads in sheet metal during installation
• Useful for repairing cosmetic or functional panel alignment issues

• Disconnect power before working on any appliance to avoid shock or injury
• Use the correct sized Phillips or Torx driver to prevent cam-out or screw damage
• Start straight and thread slowly; do not overtighten to avoid stripping sheet metal
• Replace only with the exact part number for best fit and performance

This cooling fan motor spins the internal fan that moves air through the appliance to dissipate heat and protect sensitive components. Replacing a noisy, weak, or seized motor restores proper airflow and dependable operation.

• Drives the cooling fan to circulate cooling air within the cabinet
• Helps prevent overheating and thermal shutdowns of internal parts
• Restores airflow when the original motor is worn, noisy, or not turning
• Typical signs include no fan movement, unusual humming/squealing, reduced airflow, or the unit shutting off from heat

• Disconnect power (and gas, if applicable) before servicing; allow the appliance to cool completely
• Access the motor by removing the appropriate rear/top or control-panel cover for your model
• Note wire orientation; transfer the fan blade and any mounting parts from the original motor if required
• After installation, ensure the fan spins freely and verify proper airflow and quiet operation

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 is a motor start/run capacitor that helps the appliance's motor start and run smoothly by supplying a brief boost of electrical energy. Replacing a failing capacitor restores reliable motor startup and operation. What it does:

• Provides the brief electrical surge needed to start and keep the motor running
• Commonly linked to motors that hum, fail to start, or run intermittently
• Helps prevent overheating from repeated start attempts when functioning properly
• Works with the appliance's start circuitry to ensure consistent performance

• Disconnect power to the appliance before accessing electrical components
• Discharge the capacitor and use insulated tools
• Observe polarity/terminal layout and secure connections to factory specifications
• Dispose of the old capacitor according to local electronic-waste regulations

A Tap-Tite binding-head screw used to fasten appliance panels and components where a self-tapping metal thread is required. Replaces missing or damaged fasteners to restore secure assembly and reduce vibration or rattling. What it does:

• Creates its own mating thread in thin sheet metal for a secure hold without a nut.
• Holds panels, brackets, and trim in place to prevent looseness or movement.
• Commonly used where stripped, missing, or broken screws cause rattling, misalignment, or parts that won't stay attached.
• Compatible with standard screwdrivers or nut drivers sized to the binding-head.

• Disconnect power and unplug the appliance before working on it.
• Use the correct driver bit to avoid cam-out or head damage.
• Start straight and apply steady pressure; avoid overtightening to prevent stripping the formed threads.
• If the original hole is badly damaged, assess for repair or use of a larger fastener as needed.
