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, 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.

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, BharatP. Thanks for sharing what happened with your LG Microwave (MSER2090D) model. We understand the importance of having a reliable microwave that heats your food quickly and efficiently for your daily meals. If your microwave is running but not heating, (1) we recommend performing a quick "Hard Reset" by unplugging the unit for 60 seconds and then plugging it back in. This can sometimes resolve internal control glitches. (2) Additionally, please ensure that the door is fully latched and that there are no obstructions, such as food debris, near the door seals, as a secure closure is required for the heating elements to engage. For more guidance, visit https://www.youtube.com/watch?v=pTCLNZ9l74E. We want to review your past interaction and the current status of your unit to explore available options.

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, Clyde. Thank you for reaching out about your LG Microwave (MSER2090D) model, and we understand the importance of having store‑related commitments handled clearly. Since refunds for in‑store purchases are processed directly by the retailer, one helpful step you can try is checking your bank or card statement for any pending transactions, as some refunds may take a few business days to appear depending on the payment method. You can also review LG’s product support resources here if you need assistance with your unit: https://www.lg.com/us/support/product/lg-MSER2090D.BBDELGA.

Hi, Rick. Thank you for sharing your experience with us regarding your LG Microwave (MSER2090S) model. We understand the importance of having an appliance that operates quietly and reliably throughout its daily use. When a microwave stops functioning after a short period, it is often related to the power supply or the internal door switch assembly. To troubleshoot this, please try the following: (1) Power Cycle: Unplug the microwave or flip the dedicated circuit breaker in your home's electrical panel to the "OFF" position for at least 60 seconds. Restore power and check if the unit responds.

(2) Door Switch Check: Ensure there is no debris preventing the door from latching completely, as the internal switches must fully engage for the unit to initiate a cooking cycle.

Hi there, DavidA. Thank you for sharing your experience with us. We understand your inquiry regarding the LG MSER2090D Microwave and the challenges you’re facing with its design and cooking settings. We appreciate your feedback as it helps us improve our products and customer experience.

For the release button, it’s designed for safety purposes, ensuring the door is properly opened and closed for optimal performance. However, if you're finding it inconvenient, please make sure that the microwave's manual is consulted for alternative methods of operation or any settings you might adjust to make the experience smoother.

Regarding the cook time and food settings, you can press "Quick Start" to easily set cooking times such as 1, 2, or 3 minutes without needing to go through the full menu. This can be a faster way to start your cooking session without needing to choose the food type each time.

Hi, Chris. Thanks for reaching out about your LG Microwave (MSER2090D) model. We understand the importance of having a microwave that stays reliable well beyond just a few months of use.

If the unit stopped working early on, one helpful step you can try is performing a power reset by unplugging the microwave for about 30 seconds and plugging it back in. This allows the internal control board to recalibrate and can help restore basic functions if the issue is related to the electronics. For more guidance, visit https://www.lg.com/us/support/product/lg-MSER2090D.BBDELGA. We’d be glad to take a closer look and help you move forward. Please send us an email at lgdigitalcare@lg.sprinklrsupport.com so our team can assist you directly. ^Juvy

Hi, Steven. Thank you for sharing your experience with us. We understand how important it is for your LG Microwave (MSER2090D) model to operate reliably, especially after your initial positive use.

For buzzing or cracking noises followed by the unit stopping, one helpful step is to unplug the microwave for 5 minutes and then plug it back in to reset the electronics. If the noise persists, it may indicate an issue with the magnetron or internal components, which requires inspection by an LG technician. You can review troubleshooting guidance here: https://www.lg.com/us/support/product/lg-MSER2090D.BBDELGA. Since your unit is within the first 12 months of ownership, LG covers the warranty directly. Please send us an email at lgdigitalcare@lg.sprinklrsupport.com so we can assist you further with service coordination. ^Juvy

Hi, Abia. Thank you for reaching out about your LG Microwave (MSER2090S) model. We understand the importance of having a unit that performs reliably. To optimize your model, (1) ensure it is plugged into a dedicated wall outlet, not a power strip or extension cord, for stable voltage. (2) Also, verify that the turntable ring and glass tray are properly aligned for even cooking. For more guidance, visit https://www.lg.com/us/support/product/lg-MSER2090S. If you’d like us to take a closer look at what’s happening with your unit, we’d be glad to assist further. Please send us an email at lgdigitalcare@lg.sprinklrsupport.com. We're here to help. ^Juvy

Hi, Mary. Thank you for reaching out to us. We understand the importance of having your LG Microwave (MSER2090S) model operate reliably. To address the heating issue, please try the following troubleshooting steps: Unplug the microwave for at least 60 seconds to reset the internal control board. Appliances may mistakenly switch to "Demo" or "Display" mode, causing the timer to count down without the magnetron activating. To exit this mode, open the door and press and hold the Clock or Settings button for a few seconds until "Off" or "On" appears on the display. Put a microwave-safe cup with one cup of water inside and run it on high for one minute to check for heat.
