Most common repairs needed to fix a LG refrigerator

Electronic Control Board Replacement

A defective electronic control board can lead to various failures in a refrigerator, including a lack of power or cooling and water leaking. This is because the board serves as the brain of the refrigerator, controlling crucial operations such as regulating internal temperatures, running fans, managing defrost cycles, overseeing the ice maker, and controlling dispenser functions. If the electronic control board malfunctions, it can disrupt communication between many different components, including automatic doors if equipped. A failing board may cause a chattering or clicking noise from the refrigerator and may emit a burning odor. Due to the potential impact on multiple components, it is advisable to have a Sears Home Services professional conduct diagnostic tests on the board to confirm if replacement is necessary.

Power Supply Board Replacement

A dead refrigerator power supply board can result in a complete loss of power to the refrigerator, resulting in no lights, no cooling, and no operational sounds. The display panel, if present, may be blank or unresponsive. In models with automatic doors, a malfunctioning power supply board may lead to the doors no longer opening or closing automatically as intended. In some cases, there might be intermittent power issues, where the refrigerator may work inconsistently or sporadically. Additionally, the failure of the power supply board can lead to an absence of any audible humming or clicking sounds typically associated with the refrigerator's normal operation.

User Interface Control Replacement

When a refrigerator user interface control becomes inoperative, it loses the ability to communicate with the main control board, affecting settings like temperature or ice maker status. The interface will cease to display, creating the appearance of a powerless refrigerator. In some instances, it may only show an error code. If the user interface solely controls drawer temperature settings, a crack in the shelf housing the interface can prevent it from responding to the selected settings.
