Lg Microwave Displaying ‘locked’: Unraveling The Mystery And Finding A Solution

If you’ve ever tried to use your LG microwave only to be met with the dreaded “locked” message, you know how frustrating it can be. But don’t worry, you’re not alone. This is a common problem that can be caused by a variety of factors. In this blog post, we’ll explore the various reasons why your LG microwave might be saying “locked” and provide step-by-step instructions on how to fix the issue.

Safety Lock Feature

One of the most common reasons why your LG microwave might be locked is because the safety lock feature has been activated. This feature is designed to prevent children from accidentally using the microwave, and it can be activated by pressing and holding the “Lock” button for three seconds. To disable the safety lock feature, simply press and hold the “Lock” button again for three seconds.

Door Switch Malfunction

Another possible reason why your LG microwave might be saying “locked” is because the door switch is malfunctioning. The door switch is responsible for detecting when the microwave door is closed, and if it’s not working properly, the microwave will not be able to operate. To test the door switch, open and close the microwave door several times. If the microwave still says “locked,” you may need to replace the door switch.

Control Panel Issues

In some cases, a locked LG microwave can be caused by a problem with the control panel. If the control panel is not working properly, it may not be able to send the correct signals to the microwave, which can result in the “locked” message. To troubleshoot this issue, try cleaning the control panel with a damp cloth. If that doesn’t work, you may need to replace the control panel.

Magnetron Failure

The magnetron is the heart of the microwave, and if it fails, the microwave will not be able to heat food. A failed magnetron can cause the microwave to display the “locked” message. To test the magnetron, you will need a multimeter. Set the multimeter to measure AC voltage and connect the probes to the magnetron terminals. If the multimeter reads zero volts, the magnetron is likely failed and will need to be replaced.

Power Supply Problems

If your LG microwave is not getting enough power, it may not be able to operate properly and may display the “locked” message. To check the power supply, unplug the microwave and then plug it back in. If the microwave still says “locked,” you may need to replace the power cord or the outlet that the microwave is plugged into.

Faulty Wiring

In some cases, a locked LG microwave can be caused by faulty wiring. This can be a dangerous problem, so it’s important to have it repaired by a qualified technician.

Final Note: Unlocking Your LG Microwave

If you’ve tried all of the troubleshooting steps above and your LG microwave is still saying “locked,” you may need to contact LG customer service for further assistance.
