Parts for Lg LDG3017ST/00: Controller Parts

This is a truss-head tapping screw used to secure trim, panels, and small assemblies on compatible LG appliances. It provides a low-profile, wide-bearing head that helps hold parts flush and resist pull-through. What it does:

• Fastens plastic and sheet-metal components where a self-tapping thread is needed
• Truss head spreads load to prevent damage to soft or thin materials
• Helps secure control panels, brackets, or trim pieces that require a low-profile head
• Common replacement when original mounting screws are missing, stripped, or corroded

• One truss-head tapping screw

• Use the correct screwdriver bit and moderate torque to avoid stripping the screw or workpiece
• Start threading straight and let the screw form threads without forcing at an angle
• Disconnect power and follow appliance-specific service safety procedures before working internally
• Replace any damaged mating threads or clips for a secure fit

This truss head tapping screw secures interior panels and small components on compatible appliances, restoring proper fit and stopping rattles or loose trim. It's a direct hardware replacement for a single mounting point. What it does:

• Fastens panels, brackets, and trim where a low-profile truss head is required
• Replaces missing or stripped screws that cause rattling or loose parts
• Provides a secure hold by forming threads in sheet metal during installation
• Useful for repairing cosmetic or functional panel alignment issues

• Disconnect power before working on any appliance to avoid shock or injury
• Use the correct sized Phillips or Torx driver to prevent cam-out or screw damage
• Start straight and thread slowly; do not overtighten to avoid stripping sheet metal
• Replace only with the exact part number for best fit and performance

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.
