A circular lug designed to join a stripped wire to a threaded terminal for a secure electrical connection. Helps restore reliable contact at terminals and reduces the chance of intermittent power or arcing at connection points. What it does:

• Provides a strong mechanical and electrical connection between a wire and a screw or bolt terminal.
• Helps prevent loose connections that can cause intermittent operation, sparking, or overheating.
• Commonly used where a ring-style termination is required for safe, stable wiring.
• Works with properly sized wire and fasteners to maintain consistent conductivity.

• Always disconnect power to the appliance before inspecting or replacing electrical parts.
• Use the correct lug size and gauge for the wire and terminal; crimp or solder per manufacturer recommendations.
• Tighten terminal hardware to the appliance manufacturer's specified torque; avoid over-tightening which can damage the lug or terminal.
• If wiring insulation or the terminal is damaged or corroded, replace the affected components rather than reusing them.

This small, board-mounted tactile push-button switch is used on the control panel. It registers a momentary press so the control board can accept your selection. Replacing a worn switch restores reliable button response and consistent operation.

• Mounts to the user interface board and provides momentary contact when a button is pressed
• Sends a low-voltage signal to the control, enabling cycle or option selection
• Typical failure symptoms: unresponsive or intermittent buttons, needing extra force to register, stuck/always-on input, or unintended beeps/changes
• Helps restore consistent user-interface input when an individual button switch has failed

• Disconnect power to the appliance before servicing; shut off gas/water if applicable
• Access the control panel to reach the user interface board
• This is a board-level repair; note switch orientation. Replacement may require desoldering/soldering per OEM procedure
• Use ESD precautions and avoid overheating PCB pads; test button function before reassembly

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.
