Parts for Lg FB4753LS: Controller Parts

This power control board assembly manages power distribution and control signals for the appliance's main electrical functions, restoring reliable operation when the sub control board fails. What it does

• Routes voltage and control signals between the main board and appliance components to enable normal operation.
• Replaces a damaged or faulty sub PCB that can cause intermittent power, control failures, or non-responsive cycles.
• Commonly used when the appliance won't start, shows control errors, or behaves unpredictably due to power/control faults.
• Matches OEM design to maintain original wiring connections and mounting points.

• One power control board assembly

• Disconnect power before beginning work to avoid shock or damage.
• Handle the board carefully and avoid touching components or conductive traces; observe electrostatic discharge (ESD) precautions.
• Verify board orientation, connector seating, and harness routing before restoring power.

Replace your range's control board support bracket if the PCB is loose or unstable. This mounting bracket secures the circuit board. DIY-friendly repair.

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

Fix intermittent power loss or electrical failures in your range with this wiring harness. Restores proper connections between components. Moderate DIY.

Fixes intermittent power or control issues caused by damaged wiring. This harness restores electrical connections between range components for reliable operation.

Protects your range control panel display from spills, grease, and damage. Replace when cracked, discolored, or visibility is reduced. Verify fit with your model.

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

Range not heating or turning on? The main control board manages all electronic functions. Moderate DIY repair requiring careful wire transfer to labeled terminals.

Note: Per LG, the buzzer is now built into the board and the connector harness can be left disconnected.
