Parts for Lg LMV1683ST / 00: Controller Parts

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 keypad controller assembly is the user-facing control module that accepts button input from the appliance control panel and communicates commands to the main control board, restoring reliable input and display response. What it does:

• Converts button presses into signals the main control board can read
• Restores responsive or stuck/unresponsive buttons and touch controls
• Resolves intermittent control, unregistered inputs, or loss of panel feedback
• Addresses control-related error messages when caused by a faulty keypad interface

• Always disconnect power at the breaker or unplug the appliance before servicing
• Handle the assembly and any ribbon cables gently to avoid damage; avoid touching exposed circuit traces
• Reconnect all wiring and verify correct orientation before restoring power

Power Control Board (PCB assembly) that manages incoming power and distributes voltage to the appliance's control, motor and sensor circuits. Replacing a faulty board restores reliable power delivery and control to affected components. What it does:

• Regulates and routes power to control modules, motors and sensors — symptoms include appliance not powering on, intermittent shutdowns, or failure to start cycles.
• Supplies and stabilizes voltage for the control panel and displays — symptoms include dim or blank displays and intermittent or erratic control behavior.
• Interfaces with user controls and safety switches to enable normal operation — symptoms include unresponsive buttons, stuck cycles, or error codes.
• Contains protective components that can fail visibly — symptoms may include burning smell, scorch marks on the board, or tripped breakers.

• Disconnect power (unplug or switch off breaker) before accessing the appliance.
• Photograph wiring and connector positions before removal; compare connector types and board part numbers to fit.
• Avoid touching board components and use basic ESD precautions when handling the PCB.

This metal mounting bracket secures the appliance control panel to the console, restoring a stable user interface and preventing loose or misaligned controls. It's a direct-fit replacement designed to revive panel alignment and tactile feedback. What it does

• Secures the control panel assembly to the appliance frame so buttons and display stay properly aligned
• Prevents the control panel from sagging, shifting, or vibrating during use
• Helps restore reliable button actuation and consistent control contact
• Addresses symptoms like a loose, wobbly, or misaligned control console

• One control panel mounting bracket

• Disconnect power before starting any repair to avoid shock or damage
• Access typically requires removing the console or top panel—keep fasteners organized
• Reuse OEM screws if service instructions advise; replace any stripped hardware

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

The Magnetron Thermostat is an OEM part for LG microwaves and built-in ranges. Its primary function is to monitor the temperature and ensure that it remains within a safe operating range. If the temperature exceeds the preset limit, the thermostat will interrupt the power supply to the magnetron, preventing overheating and potential damage.

Causes of a faulty magnetron thermostat can include electrical malfunctions, component failures, or physical damage. These factors can result in issues such as erratic heating, microwave not heating properly, or the appliance shutting off unexpectedly.

Symptoms of a bad magnetron thermostat may include:

• Microwave not heating food evenly or at all
• Inconsistent or weak heating performance
• Microwave shutting off or displaying error codes related to temperature issues

This OEM LG part can also be used on Kenmore/Sears appliances.
