Parts for Lg LRG4115ST: Controller Parts

This PCB assembly houses the side key control circuitry that registers user button presses and relays commands to the appliance's main control system. Replaces a faulty side-key board to restore responsive side controls and reliable input signaling. What it does:

• Receives and processes side button/key inputs and sends signals to the main control board
• Restores unresponsive or intermittent side-panel buttons and touch keys
• Helps stop incorrect or phantom commands caused by a damaged side-key circuit
• Works as the dedicated control interface for side-mounted user inputs

• Disconnect power to the appliance before any disassembly to avoid shock or damage
• Handle the board carefully and avoid touching contacts; protect against static discharge
• Confirm connector orientation and seating during reassembly; do not force pins

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 Display Cover is an OEM part for LG ranges. It covers and shields the control panel display located at the top of the range. This protective cover helps prevent damage from spills, splatters, and accumulated grease and grime that could compromise visibility and functionality over time.

Causes of a bad display cover include normal wear and tear from repeated cleaning, exposure to heat and cooking vapors, or accidental damage from impact.

Symptoms of a bad display cover may include:

• Cracks or clouding of the plastic material
• Missing mounting screws or clips
• Grease or grime build-up that cannot be fully cleaned
• A cover that is loose, warped or no longer fully seals the display

This OEM LG part is also compatible with some Kenmore models.

This is the appliance's primary electronic control module. It manages power distribution and coordinates functions based on user input and sensors to restore reliable operation when the original board fails or becomes unresponsive.

• Controls and synchronizes key electronic functions per the unit's design
• Distributes power and signals to components such as motors, valves, fans, heaters, or pumps
• Common symptoms of a failing board: no power, won't start, unresponsive or erratic controls, intermittent operation, or recurring error codes
• Can resolve issues following electrical surge or visible board damage

• Disconnect electrical power before servicing; shut off water/gas if applicable
• Handle the PCB by the edges and use ESD protection to avoid static damage
• Photograph/label all connectors and transfer them one at a time to the new board
• Some models may require option-code entry or service-mode setup after installation; refer to your model's service documentation

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:

• Carries power and control signals between specific components
• Restores interrupted circuits that can cause intermittent operation or component failures
• Helps resolve symptoms like no power to a component, inconsistent function, or error codes tied to open/shorted wiring
• Provides factory-style connectors for a direct fit and reliable connections

• Disconnect power (unplug or turn off breaker) before installing to avoid shock or damage
• Inspect connectors and routing, match connector types and wire colors before connecting
• Avoid pinching or sharply bending wires; secure harness using existing clips or ties

The Supporter, PCB Range is an OEM component specifically designed for LG ranges. This part supports and protects the Printed Circuit Board (PCB) which controls many of the range's electronic functions. 

Over time, the plastic housing and clips that make up the PCB Supporter can weaken or become brittle due to heat exposure inside the oven. This repeated heating and cooling can cause cracks or breaks which compromise the protection of the circuit board. 

Symptoms of a bad PCB Supporter include:

• Exposed or loose PCB that is at risk for impact damage  
• The circuit board that does not seat properly or makes poor contact
• Intermittent or unpredictable function of electronic controls

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