This OEM LG part is also compatible with Sears/Kenmore ranges. Replace yours today with this genuine electronic control board and upgrade the functionality of your electric range oven.

This PCB assembly is the appliance's main control board that manages cycle commands, sensor signals and user inputs to keep the appliance operating correctly. Replacing a faulty board restores control and communication functions. What it does:

• Receives inputs from the control panel and sends commands to motors, valves and heaters
• Monitors sensor signals and timing functions to coordinate cycles
• Stops operation or causes errors if the board fails or loses power
• Common symptom link: unresponsive controls, error codes, or appliance that won't start

• One PCB assembly (control board)

• Disconnect power before starting and verify power is removed to avoid shock
• Handle the board carefully and avoid touching components or connectors; observe electrostatic discharge (ESD) precautions
• Inspect connectors and wiring for damage and ensure secure connections during reassembly

This control board assembly directs power and communication to key components, interpreting inputs and sensor signals so the appliance runs the correct functions and cycles. Replaces a failed electronics module to restore reliable operation.

• Distributes power and control signals to major components per the unit's programmed logic
• Interfaces with sensors and the user controls to execute selected functions
• Coordinates cycle timing and safety monitoring
• Common signs of failure: no power or won't start, unresponsive controls/display, intermittent operation, error codes, or unexpected shutdowns

• Disconnect power to the appliance before servicing
• Handle the board by the edges; use ESD protection to avoid static damage
• Photograph and label connectors, then transfer them one at a time to the new board
• Secure wiring to avoid pinching; follow the unit's tech sheet or service manual

The Encoder Board is an OEM part for LG ovens. This board is responsible for interpreting the inputs from the control knobs and buttons on the oven's control panel. It sends these signals to the main control board, which then adjusts the oven settings accordingly, such as temperature and cooking mode.

Causes of a bad encoder board can include electrical surges, wear and tear from frequent use, or physical damage to the board's components. A malfunctioning encoder board can disrupt the communication between the user interface and the oven's control system.

Symptoms of a bad encoder board include:

• Unresponsive control knobs or buttons
• Incorrect oven temperature settings
• Oven not starting or turning off unexpectedly
• Error codes displayed on the control panel

This OEM LG part is also compatible with Sears/Kenmore.

This control panel is the front user interface that lets you select cycles and settings so the appliance responds to commands and displays status. It replaces a cracked, faded, or unresponsive front control surface to restore normal operation. What it does:

• Houses the touchpad/buttons and display area that register user input and show cycle status.
• Allows selection and confirmation of wash/dry cycles, options, and settings.
• Commonly replaces panels that are cracked, scratched, or have worn-off markings.
• Can resolve issues where buttons do not respond or the control surface is damaged.

• Disconnect power to the appliance before beginning any work to avoid shock.
• Replacement typically requires removing the top or front trim and a few screws; handle the panel gently to avoid damaging the display or bracket tabs.
• Keep screws and small parts organized and verify alignment before tightening.

The Oven Selector Knob Supporter is an OEM replacement part for LG ovens. It is a crucial component that provides structural support and ensures proper functioning of the oven selector knob mechanism.

Symptoms of a bad oven selector knob supporter:

• Loose or wobbly oven selector knob
• Difficulty in turning or selecting oven functions
• Knob becoming detached or falling off
• Misalignment or binding of the knob mechanism

Causes of a faulty oven selector knob supporter can include physical damage, wear and tear over time, or manufacturing defects that compromise its structural integrity or alignment.

This OEM LG part is also compatible with Sears/Kenmore ovens.

This single wiring harness connects appliance components to route power and signals reliably, restoring electrical continuity for normal operation. It's a direct-fit replacement when the original harness is damaged or corroded. What it does:

• Carries power and control signals between components so circuits complete and controls respond
• Replaces frayed, burned, or broken wiring that can cause intermittent operation or loss of function
• Helps stop shorts, arcing, or connector-related failures when the original harness is compromised
• Matches OEM connector types and pin arrangements for an accurate replacement

• Disconnect power (unplug appliance or switch off breaker) before beginning any work
• Handle connectors gently; avoid pulling on wires—release locking tabs first
• Route and secure the harness away from hot surfaces and moving parts to prevent wear

This single wiring harness routes electrical power and signals between components to restore proper connections and reliable operation. It replaces a damaged or worn harness to help eliminate intermittent power or control issues. What it does:

• Transfers power and control signals between appliance components to maintain proper function
• Replaces frayed, burnt, or damaged wiring that can cause intermittent operation or component failure
• Helps resolve symptoms like loss of power to a module, erratic behavior, or failure to respond
• Provides a direct plug-and-play connection when matching the correct factory harness

• Disconnect all power (unplug or switch off circuit breaker) before starting any work
• Handle connectors gently and seat firmly until they click into place

This is a single wiring harness that routes power and signals between appliance components to restore reliable electrical connections. It replaces a damaged or worn harness so controls and features can communicate properly. What it does:
