You rely on your LG microwave’s clock to accurately time your cooking and keep track of the hour. But lately, you notice the display randomly flickers and blinks – 10:23 rapidly becomes 10:22 before switching back again. While not a serious appliance issue, this glitchy clock can be incredibly distracting and make it difficult to use key functions.
Before you uninstall your LG microwave in frustration, know that this is often an easy fix. In this post, we’ll explain what commonly causes the clock display to flicker and how to troubleshoot the problem. With a few simple steps, you can banish the blinking for good and have your clock working normally again.
Don’t live with a frustratingly flickering display! We’ll show you how to decode this issue and implement the targeted fix. Let’s shed some light on restoring your LG microwave’s clock to full brightness and stability.
The main reason why your LG microwave clock flickers is because of a loose or faulty display connector cable. To fix it, you need to unplug the microwave, remove the front casing, and reattach the connector cable firmly.
Why does my LG microwave clock flicker?
The clock display on your LG microwave is connected to the control board by a thin plastic strip called an elastomeric connector. This connector has metal contacts that transmit electrical signals from the board to the display. Sometimes, this connector can become loose or dirty, causing a poor connection and resulting in a flickering display.
Another possible cause of a flickering display is a faulty display board. The display board is the circuit board that controls the LED lights on the display. If the board is damaged or malfunctioning, it can cause the display to flicker or dim.
A less common cause of a flickering display is a short-circuit in the microwave. This can happen if water or moisture gets inside the microwave and causes an electrical arc. This can damage the components and wires inside the microwave and affect the display.
How to fix a flickering LG microwave clock
The first thing you need to do is unplug your microwave from the power outlet. This is important for your safety and to prevent further damage to your microwave.
Next, you need to remove the front casing of your microwave. This may vary depending on your model, but usually you need to unscrew some screws on the back or side of the microwave and then slide off the casing.
Once you have access to the control board, locate the display connector cable. It should be a thin plastic strip with metal contacts on both ends. It should be plugged into a socket on the control board, usually in the top right corner of the microwave.
Check if the connector cable is loose or dirty. If it is loose, push it firmly into the socket until it clicks. If it is dirty, use some alcohol and a cotton swab to gently clean the contacts on both ends of the cable.
After you have reattached or cleaned the connector cable, put the casing back on your microwave and screw it in place. Plug your microwave back into the power outlet and test if the display still flickers.
If this does not fix your problem, you may have a faulty display board or a short-circuit in your microwave. In that case, you may need to replace the display board or contact a professional technician for repair.

A: To replace your display board, you need to follow similar steps as fixing a loose connector cable. You need to unplug your microwave, remove the front casing, and locate the display board.
