Lre 30453St/10 Parts

This electronic control board (sub PCB assembly) is the "brain" of the appliance. It interprets user inputs and sensor feedback to power the correct components at the right time, restoring normal operation when the original board fails.

• Regulates power and timing to motors, fans, valves, and heaters based on selected settings and sensor inputs
• Interfaces with the user/display controls to execute cycles and options
• Common symptoms include no power or won't start, unresponsive or erratic controls, intermittent shutdowns, or random beeping
• May store or trigger error codes related to control or power faults

What's included: 1 electronic control board assembly Install notes:

• Disconnect electrical power before servicing; verify power is off with a meter where applicable
• Use anti-static handling; avoid touching component pins and traces
• Photograph wiring; move connectors one at a time and confirm locking tabs are fully seated
• Mount securely and route harnesses as original; follow the service manual for any required configuration or test modes after installation

Replacement display power control board assembly that restores display and control-panel functions on compatible LG appliances. Installs into the control module to address blank or erratic displays and unresponsive panel controls. What it does:

• Powers and drives the control-panel display and associated buttons/touch inputs.
• Relays user commands from the control panel to the appliance's main control board.
• Resolves symptoms such as a blank or dim display, unresponsive buttons, flickering or garbled characters, and intermittent display errors.
• Requires the correct part number for proper fit and function.

• Disconnect power to the appliance before beginning any service to avoid electrical shock.
• Handle the PCB by its edges and use antistatic precautions; avoid touching components or solder joints.
• Photograph or label all connectors before removal so wiring can be reinstalled correctly.

This power control board assembly regulates power to the appliance's control and motor circuits so the unit runs reliably and responds to user inputs. Replaces a failed sub power board to restore normal electrical control. What it does:

• Routes and distributes power to control circuits and related components
• Works with the main control to manage motor, heater, and user-interface functions
• Can cause no-power, intermittent operation, or control/display errors when faulty
• Helps stop erratic starts, unexpected shutdowns, or failure to respond to controls

What's included:

• One power control board assembly (as shown)

Install notes:

• Always disconnect the appliance from power before starting service
• Handle the board by its edges and avoid static discharge; use ESD protection if available
• Verify connector orientation and seating; replace only if this exact assembly is required
• If symptoms persist after replacement, test related components and wiring harnesses
