Lg Range MB4349H Parts

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

Connects the turntable motor to the glass tray hub so it rotates during cooking. Replace this shaft coupler if it's cracked, worn, melted, or broken.

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.

This is an AC synchronous motor that drives the turntable glass tray inside the microwave. It rotates the tray slowly during cooking to ensure food heats evenly. Replace this motor if the turntable has stopped spinning, turns intermittently, or makes a buzzing or humming noise without rotating.

Microwave not heating or sparking inside? This high voltage capacitor stores power for the magnetron. Common repair taking 30-45 minutes with care.

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

Secures interior panels and components. Replace when stripped, corroded, or missing to stop rattles and secure loose trim. Verify fit with your model number.

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.

This is a circular wire harness holder that secures and organizes internal wiring within the range. It clips onto the frame or mounting points to keep wires routed properly and away from heat sources. Replace this part if it is broken or missing, which can cause loose wiring or potential contact with hot surfaces.

Insulator cover protects internal components from heat. Replace this part if your original cover is cracked, broken, melted, or missing from your appliance.

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

Microwave won't turn on or stopped working suddenly? This fuse protects your microwave from power surges. Simple DIY fix with basic tools in 15 minutes.

Microwave won't heat but runs normally? This magnetron generates microwave energy to cook food. Requires high-voltage safety knowledge to replace.
