The LG LMC2075ST microwave is a popular kitchen appliance known for its convenience and efficiency. However, like any electronic device, it may encounter issues from time to time. In this article, we will explore common problems that users may face with the LG LMC2075ST microwave and provide troubleshooting tips to help resolve these issues.
Microwave Not Heating
One of the most common issues with microwaves is when they fail to heat food properly. If you find that your LG LMC2075ST microwave is not heating, try the following troubleshooting steps:
- Check the power source: Ensure that the microwave is properly plugged into a functioning power outlet. If the outlet is working, try plugging the microwave into a different outlet to rule out any electrical issues.
- Reset the microwave: Sometimes, a simple reset can resolve the issue. Unplug the microwave from the power source, wait for a few minutes, and then plug it back in. This can help reset any internal components that may have malfunctioned.
- Check the door latch: The microwave door must be closed securely for it to operate properly. Make sure that the door is fully closed and that the latch mechanism is engaging properly. If the latch is damaged or misaligned, it may need to be replaced.
- Test with different power levels and time settings: Sometimes, the issue may be with the power level or time settings. Test the microwave with different settings to see if the heating issue persists. If it only occurs with specific settings, there may be a problem with the control panel or the internal circuitry.
If none of these troubleshooting steps resolve the heating issue, it is recommended to contact LG customer support or a qualified technician for further assistance.

Microwave Turntable Not Rotating
Another common issue with microwaves is when the turntable fails to rotate. If you are experiencing this problem with your LG LMC2075ST microwave, try the following troubleshooting tips:
- Check for obstructions: Inspect the turntable and the area underneath it for any obstructions that may be preventing it from rotating. Remove any debris or objects that may be blocking the movement.
- Clean the turntable and roller ring: Over time, food particles and grease can accumulate on the turntable and roller ring, hindering their movement. Remove the turntable and roller ring from the microwave and clean them thoroughly. Make sure they are dry before placing them back in the microwave.
- Check the turntable motor: The turntable motor is responsible for rotating the turntable. If the motor is faulty or damaged, it may need to be replaced. Contact LG customer support or a qualified technician for assistance with motor replacement.
- Test with different settings: Try operating the microwave with different power levels and time settings to see if the turntable rotates. If it only fails to rotate with specific settings, there may be an issue with the control panel or the internal circuitry.
If these troubleshooting steps do not resolve the turntable rotation issue, it is recommended to seek professional assistance.

Microwave Display Not Working
If the display on your LG LMC2075ST microwave is not working, follow these troubleshooting tips:
- Check the power source: Ensure that the microwave is properly plugged into a functioning power outlet. If the outlet is working, try plugging the microwave into a different outlet to rule out any electrical issues.
- Reset the microwave: Similar to the troubleshooting step for heating issues, try resetting the microwave by unplugging it from the power source for a few minutes and then plugging it back in. This can help reset any internal components that may have malfunctioned.
- Check the control panel: Inspect the control panel for any physical damage or buttons that may be stuck. If any buttons are stuck or damaged, they may need to be replaced. Contact LG customer support or a qualified technician for assistance with button replacement.
- Test with different settings: Try operating the microwave with different settings to see if the display starts working. If the display only fails to work with specific settings, there may be an issue with the control panel or the internal circuitry.
