Parts for Lg LDG3017ST: Controller Parts

This replacement power control board is the main PCB that manages and distributes electrical power to the appliance's components, restoring proper power-related functions and control when the original board fails. What it does:

• Regulates and supplies voltage to motors, sensors, and user interface circuits
• Controls startup and shutdown sequences for safe operation
• Helps stop symptoms like no power, intermittent power loss, or erratic component behavior
• Works with other control boards and sensors to maintain normal appliance operation

• Disconnect power (unplug or trip breaker) before servicing to avoid shock
• Wear an anti-static wrist strap or discharge static before touching the board
• Verify connector locations and cable seating match the original before reassembly

Power Control Board Assembly manages power distribution and electronic control for the appliance, restoring proper sequencing, user-interface response, and safety interlocks so the unit operates reliably when the original board fails. What it does:

• Regulates power to major components and coordinates operational sequencing for cycles and functions.
• Processes inputs from the control panel and sensors to start, stop, and change modes.
• Common symptoms that indicate board failure: no power or display, unresponsive controls, intermittent operation, or erratic behavior.
• Replaces a damaged or burned control board that causes electrical or control faults.

• Disconnect all power to the appliance before servicing to avoid shock or damage.
• Handle the board by its edges and use static-safe precautions (ESD wrist strap recommended).
• Inspect wiring harnesses and connectors for heat damage or corrosion; ensure secure connections when installing the new board.

Factory replacement parts assembly that replaces a damaged or worn internal assembly to restore the appliance's original operation. Use to replace a failed assembly and return the affected functions to working order. What it does:

• Replaces a defective internal assembly to restore the specific subsystem supplied by that assembly.
• Can resolve symptoms such as intermittent operation, unresponsive component behavior, or loss of the affected function.
• Restores electrical and mechanical connections that may have failed at the assembly level.
• Fits in the original mounting points and connects to existing wiring harnesses when matched to the correct part number.

• Always disconnect power (and water supply if applicable) before beginning service.
• Handle connectors and wiring carefully; avoid pulling on wires—use proper tools for connector release.
• Follow the appliance service manual for disassembly/reassembly steps and torque specifications.
