Parts for Lg LMV1683SB: 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 replaces the user control board that registers button presses and sends commands to the appliance, restoring normal control and cycle selection. Ideal when buttons are unresponsive or the control panel fails to register inputs. What it does:

• Receives and interprets keypad/button presses and transmits user commands to the main control
• Restores tactile/signal response for cycle selection, start/pause, and other front-panel functions
• Resolves symptoms like unresponsive buttons, intermittent control operation, or missing user input feedback
• Works with the existing display and wiring harness to reinstate normal front-panel control

• Disconnect power (unplug or disconnect appliance breaker) before installing
• Handle the assembly carefully; avoid touching circuit contacts or bending connectors
• Verify connector orientation and seat harnesses fully before reassembly
• Test operation after reinstalling the control panel; if problems persist, check wiring and the main control

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

This genuine replacement parts assembly restores the original component grouping to bring your appliance back to proper operation. It replaces worn or damaged factory parts so the unit can function as intended. What it does

• Replaces the original factory parts grouping that controls or supports a specific appliance function
• Restores fit and connection points for reliable operation after part failure or damage
• Helps stop symptoms caused by a failed assembly, such as intermittent function, loose fittings, or visible damage
• Matches OEM mounting and connection interfaces to simplify reassembly

• One complete parts assembly as shown

• Follow manufacturer service manual
• Disconnect power and water (if applicable) before starting work to avoid shock or leaks
• Handle connectors and wiring carefully to avoid damage; verify proper routing and secure fasteners

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.
