LG Microwave Oven PCB Assembly,Main

The LG Microwave Main PCB Assembly (Part Number / SKU: EBR73020626) is a genuine OEM main control board for compatible LG microwave ovens. The main PCB is the brain of the microwave: it reads every keypad press, runs the cooking programmes and timer, and switches the relays that power the magnetron, heaters, turntable motor, lamp and cooling fan. Power surges, voltage fluctuations or moisture can damage the board, leaving the oven dead, the display blank, buttons unresponsive or the oven starting and stopping on its own. This original LG main PCB assembly restores full control and factory cooking functions.

Key Features

Safety Instructions

Microwave ovens contain a high-voltage capacitor that can hold a dangerous charge even after the unit is unplugged. Always disconnect mains power and safely discharge the high-voltage capacitor before opening the cabinet. Installation should be carried out by a qualified technician. Never operate the oven with the outer cabinet removed. Handle the board by its edges and avoid touching components to prevent static damage.
