About this item

The LG Microwave Main PCB Assembly (Part Number / SKU: EBR73020625, Board ID: P-A640831, Right Mount for 21L Convection Keypad Models) is an authentic OEM electronic control board designed for select LG convection microwave ovens, including the MC2146BP and MC2146BL series. The main printed circuit board (PCB) acts as the central nerve center, processing inputs from the keypad interface and regulating high-voltage relays, magnetron power, convection heating elements, and cooling fans. Over time, power surges, electrical shorts, or moisture exposure can damage internal microcontrollers or traces, leading to a dead unit or unresponsive buttons. This genuine OEM replacement board restores factory-calibrated cooking performance and electrical safety.

Key Features

  • OEM Central Processing Unit: Factory-programmed main control board designed specifically for exact model compatibility and seamless communication across all internal microwave peripherals.

  • Integrated Power & Relay Switching: Features robust onboard relays, transformers, and microprocessors to handle heavy-duty convection and microwave electrical loads safely.

  • Precise Firmware Integration: Comes pre-loaded with official microwave operating logic to manage precise convection temperatures, cooking power levels, and error monitoring.

Benefits

  • Solves major microwave failures like complete lack of power, unresponsive keypad buttons, failure to heat or convection bake, and persistent electronic error codes.

  • Restores factory-grade operational reliability and electrical safety.

  • Direct plug-and-play wiring harness integration eliminates modification hurdles during advanced servicing.

Applications

Designed for LG 21-liter convection microwave keypad models including MC2146BP and MC2146BL series requiring part number EBR73020625 / P-A640831.

What's Included

  • 1 x Genuine LG Microwave Main PCB Assembly Control Board (EBR73020625 / P-A640831)

Usage Instructions

1.Unplug & Discharge:Prep.

Disconnect the microwave entirely from the main AC electrical power outlet and allow all internal high-voltage capacitors to discharge fully before touching any internal components.

2.Swap & Connect:Replace.

Remove the outer cabinet housing, carefully unclip and photograph all wiring harnesses connected to the old board, unscrew the mounting chassis, install the new EBR73020625 PCB, and reconnect all plugs securely.

Safety Instructions

Safety Warning

Microwaves contain high-voltage capacitors that can retain a lethal electrical charge even when unplugged. Always discharge capacitors safely before servicing. Electrostatic discharge (ESD) precautions should also be observed when handling circuit boards.

Care Instructions

  • Ensure the electronic compartment remains completely dry, clean, and free from dust or moisture accumulation to prevent premature board failure.
