Mt4155sp Parts

This is a high voltage diode wire assembly used in the microwave's power circuit. It works with the capacitor and magnetron to convert electrical current and generate microwave energy for cooking. Replace this part if the microwave runs but does not heat, or if the diode has visibly burned or shorted out.

Supports the turntable drum for smooth rotation. Replace if cracked, broken, or worn to eliminate scraping noise and restore stable spinning action.

Replace your cracked or broken microwave glass turntable tray to restore even heating. This rotating tray sits on the roller ring for smooth operation.

Fix a microwave that won't heat with this high voltage capacitor. Stores electrical charge to power the magnetron. Replace if heating has stopped.

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

Mounting screw secures panels, brackets, and trim to the appliance frame. Replace if screw is stripped, missing, or damaged to restore secure fastening.

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 lever release restores the lever that engages and releases an appliance latch so doors, drawers or dispensing components open and operate smoothly. It fits where a snapped or worn lever prevents normal release action. What it does:

• Replaces a broken, cracked or worn release lever that won't operate
• Restores proper engagement so door, drawer or dispenser can open and close correctly
• Helps stop sticking, slipping or incomplete release when you press or pull the lever
• Matches OEM form and function for a direct fit where specified

• One lever release

• Disconnect power (and water if applicable) before beginning service
• Remove exterior trim or access panels to reach the lever assembly; keep small fasteners organized
• Inspect surrounding latch components; replace any damaged clips or springs for reliable operation

If your microwave overheats or shuts off during use, the cooling fan motor may have failed. This motor circulates air to prevent component damage.

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

Mounting screw for microwave installation and panel assembly. Replace if stripped, missing, or damaged during maintenance. Essential hardware component.

Wire harness for microwaves. Connects internal electrical components. Replace if wires are frayed, damaged, or connections are loose or corroded.
