Lg Microwave MT4155SPT Parts

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

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

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.

This is a wire holder clip used inside a microwave to secure and route internal wiring. It keeps wires organized and safely positioned away from heat sources and moving components. Replace this holder if it is broken or missing, which can allow wires to hang loose and potentially contact hot surfaces or interfere with other parts.

This control panel is the user interface assembly that houses the touchpads, buttons and display used to select and monitor appliance cycles. It restores responsive controls and a clear display so you can operate the appliance normally. What it does:

• Provides the front-facing buttons/touchpad and display used to start and change cycles
• Replaces cracked, damaged, or unresponsive control surfaces and worn button labels
• Restores normal input response when pushpads or touch controls fail
• Works with the appliance's electronic control to show status and error codes

• Disconnect power to the appliance before starting any repair to avoid shock
• Handle the display and ribbon/connectors carefully to prevent damage
• Some installations require removing trim or the outer door/panel—keep fasteners organized
