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

A small replacement fastening nut used to secure components on LG appliances. Replacing a worn or missing nut restores a secure fit and helps eliminate looseness or rattling for reliable operation. What it does

• Fastens and secures mating parts or hardware on appliance assemblies
• Stops movement that can cause rattling, vibration, or misalignment
• Useful when a nut is stripped, lost during service, or damaged
• Helps maintain safe, stable operation of the repaired area

What's included One nut as shown Install notes

• Disconnect power and water before servicing the appliance
• Verify the nut matches the original by thread, size, and profile before installation
• Hand-thread first to avoid cross-threading, then tighten with the correct tool; avoid overtightening
• Keep small parts away from children and pets during repair

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

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

• Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
• Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
• Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
• Use when the existing sensor fails to report correct temperatures or the part number matches.

• Always disconnect power to the appliance before servicing to avoid shock or damage.
• The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
• Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.

A replacement glass shelf that provides a sturdy, easy-to-clean surface for storing food inside your refrigerator. Restores lost or damaged shelving to help keep items organized and stable. What it does:

• Replaces a cracked, chipped or missing interior glass shelf so food no longer sits unevenly or risks falling.
• Provides a solid, flat surface for bins, containers and loose items.
• Helps maintain proper airflow by fitting into the intended shelf supports.
• Matches original OEM fit and finish for a flush, secure installation.

• Remove all items from the surrounding area and support adjacent shelves before installing.
• Slide into existing shelf tracks until it rests securely on the supports; do not force.
• Handle with care to avoid chipping; wear gloves to reduce cut risk.
• If glass is broken, remove debris carefully and unplug the appliance before cleaning the area.

A flat washer used with the appliance's fastening hardware to distribute load and reduce wear. Helps maintain secure connections and prevents damage to mating surfaces for reliable operation. What it does:

• Provides an even bearing surface for bolts or screws to prevent pull-through
• Reduces friction and wear between fasteners and housing parts
• Helps keep fasteners tight and resists loosening from vibration
• Commonly used where a smooth, protective spacer is needed

• Verify correct location and orientation before reassembly
• Use manufacturer-recommended fasteners and torque specifications
• Power off and unplug the appliance before accessing internal components

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 4.0x16mm tapping screw secures trim and internal components on compatible appliances, providing a reliable fastener for repair or reassembly. Use the correct screw to maintain fit and function during service. What it does:

• Fastens appliance panels, brackets, and small components where a self-tapping thread is required
• Replaces stripped or missing screws that cause loose panels or rattling
• Helps restore proper alignment and secure electrical or mechanical parts
• Suitable where a 4.0 x 16mm size and tapping/sharp thread are specified

• One 4.0x16mm tapping screw (quantity: 1)

• Use the matching screw location and thread engagement; do not force a misaligned fastener
• Tighten until seated; avoid over-torquing which can strip threads or crack plastic
• Disconnect power and follow appliance safety procedures before servicing
• If screws repeatedly strip, inspect mating threads or use an approved repair insert

This thermostat is a temperature-sensitive safety switch used in LG microwaves. It monitors internal temperature and opens the circuit when overheating is detected to help protect components from heat damage.

• Monitors temperature at its mounting location inside the microwave
• Opens on overtemperature to interrupt power for safety
• Depending on model/location, a failed or open thermostat can cause no heat, the unit shutting off mid-cycle, or no power until it cools
• Helps prevent damage to the magnetron, cavity, and wiring due to overheating

• Unplug the microwave before service; the high-voltage capacitor can retain a dangerous charge
• Note wire positions, remove mounting screws, and install the new thermostat flat against the surface for proper heat sensing
• Reassemble and test; ensure vents and filters are clear to maintain proper airflow and prevent future overheating

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
