Lg Wall Oven 87440 Parts

The Time Delay Fuse is an OEM part for LG microwaves. This fuse provides a safety mechanism by delaying the flow of electricity, protecting the microwave's electrical components from power surges and ensuring the appliance operates safely. It helps to prevent immediate damage in the event of a power surge or electrical fault, thus prolonging the lifespan of the microwave.

Over time, the time delay fuse can become damaged due to electrical surges, wear and tear, or faulty connections. If the fuse blows, it can disrupt the microwave’s ability to function correctly.

Symptoms of a bad time delay fuse include:

• The microwave not turning on
• No response from the microwave control panel
• The microwave stopping unexpectedly during operation
• Electrical issues or blown circuits in the microwave

This OEM LG part is also compatible with Sears/Kenmore models.

Microwave won't heat but runs normally? A failed magnetron is the likely cause. This part generates the microwaves that cook food. Moderate DIY repair.

Microwave door won't stay closed or latch? This door latch spring provides tension to secure the door shut. DIY repair in under 10 minutes with video help.

The Interlock Door Switch is an OEM part for LG microwaves. It is a safety component located on the door of the microwave designed to prevent the microwave from operating unless the door is securely closed. The interlock door switch works with the microwave's electronic control board to sense when the door is open or closed and allow or disallow operation accordingly.

Causes of a bad interlock door switch can include normal wear and tear from repeated opening and closing of the microwave door over time.

Symptoms of a bad interlock door switch include:

• The microwave runs or heats with the door open
• Error codes or diagnostic messages related to door sensors on the control board
• The microwave fails to operate even when the door is securely closed

This OEM LG part is also compatible with some Sears/Kenmore microwaves.

Microwave won't heat or makes loud buzzing noise? The diode regulates magnetron current flow. Simple repair—test with multimeter for continuity.

Turntable stopped turning or making noise? This microwave motor rotates the glass tray for even heating. Easy DIY fix with basic tools in under an hour.

Fix a microwave that won't start or runs with the door open. This door interlock switch ensures safe operation by detecting when the door is fully closed.

Microwave won't start or stops mid-cycle? This door latch assembly engages door hooks and activates interlock switches to restore proper operation.

Microwave won't heat? A failing high-voltage capacitor disrupts the heating circuit. This part stores electrical energy for consistent operation.

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 thermostat controls refrigerator temperature to help maintain proper cooling and prevent spoilage. It replaces a failed or inaccurate temperature control to restore consistent operation. What it does:

• Senses internal temperature and signals the compressor to cycle on/off
• Helps keep food at steady, safe temperatures when functioning correctly
• Commonly replaces thermostats that cause warm temperatures or inconsistent cooling
• Works as a direct replacement when matching the OEM part number

• Always disconnect power to the appliance before servicing to avoid shock or injury
• Handle the sensor and terminals carefully; avoid bending or damaging components
• Basic hand tools are typically required; follow your model's service manual for exact instructions

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

Replacement mounting screw for microwave installation and assembly. Use when original screws are lost, stripped, or damaged during service or relocation.

Base plate for microwaves. Installs at the bottom of the unit to provide structural support. Replace if cracked, warped, broken, or missing.

Truss head tapping screw secures panels, brackets, and covers in appliances. Replaces missing or damaged fasteners to restore snug fit and alignment.

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.
