Customer Ratings & Reviews

Hi, there. Thank you for sharing your experience with your LG Microwave (MSER2090S) model. We understand the importance of having a microwave that performs well and stays stable during everyday use—especially when features like Sensor Cook are meant to make things easier, not more difficult.

To help improve performance, one step you can try is ensuring the microwave’s leveling feet are properly adjusted. Slightly extending the front feet can help keep the unit from shifting when opening the door. For the Sensor Cook feature, wiping the humidity sensor area inside the cavity can also help the microwave read steam levels more accurately during cooking. You can explore more details about your model here: https://www.lg.com/us/cooking-appliances/lg-mser2090s-counter-top-microwave. We’d be glad to assist you further.

Hi, there. Thank you for sharing your experience with your LG Microwave (MSER2090S) model. We understand how important it is for a microwave’s controls and alerts to work consistently.

Here’s a helpful step you can try:
A power reset can often stabilize the touch controls. Unplug the microwave for about 60 seconds, then plug it back in directly to a wall outlet. This refreshes the control board and can improve touch sensitivity and sound behavior.

Hi, Darwin. Thank you for reaching out about your LG Microwave (MSER2090S) model. We understand the importance of having your microwave operate reliably.

One helpful step you can try is performing a power reset by unplugging the unit for about 30 seconds and plugging it back in. This can help clear minor electronic glitches that may prevent the microwave from powering on or responding. You can also ensure the door is fully aligned and closing securely, as the safety interlock system will prevent operation if the door isn’t making proper contact.

Hello there, Alan. We understand your inquiry and are concerned to hear that your LG MSER2090S Countertop Microwave arrived with damage to both the packaging and unit.

One troubleshooting step you can try—should you receive another microwave—is to first inspect the door latch and seal by closing the door firmly and selecting a 10-second cook cycle with a cup of water inside. This quick test will confirm that the microwave’s interlock switches and heating element are functioning correctly before regular use.

Hello there. Thank you for sharing your experience with us regarding your LG 2.0 Cu. Ft. Countertop Microwave with Sensor Cooking and Smart Inverter. We understand your inquiry and your serious concern about the mica sheet (waveguide cover) malfunctioning, causing a "frying" or "thunderstorm" effect inside the unit shortly after purchase. This is certainly not normal or safe operation, and we are glad you were able to address it quickly through your membership.

The mica sheet protects the microwave's components, and when it fails like this, it is often due to food debris or grease accumulating on it, leading to arcing, or in rare cases, a product defect. Since the unit was returned, we would like to confirm the details of the issue for our quality control.

Hi, Diana. Thank you for taking the time to share your experience with the LG Microwave (MSER2090S) model. We’re glad to hear you’re enjoying some of its features, but we understand your concern about the notification sound is too low to be useful—especially if you rely on audio cues in the kitchen. We strive to provide high-quality products that exceed our customer's needs and expectations.

This model does not offer volume adjustment for the end-of-cycle sound. We appreciate you going the extra mile to research and reach out to us, and your feedback is valuable as we continue working to improve future designs.
