LG Keypad is simply awful
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I wanted to give the product a single star, but the microwave works fine if you can turn it on. This oven has the worst keypad imaginable. No tactile feedback. No visual cue for the location of each button. Hard to believe LG couldn’t design an ergonomic keypad.

Posted .Hi, Mark. Thank you for sharing your experience with us. We’re glad to hear that your LG Microwave (MSER0990S) model works fine once it’s on, but we understand your concern with the keypad design.

To improve the experience, we suggest pressing the buttons more firmly to ensure they register, as sometimes a slight adjustment in pressure can help.

Microwave

Posted .Hi, TaquannaW. Thank you for reaching out, and we understand the importance of having your LG Microwave (MSER0990S) model work right away. A microwave that shows no signs of power can sometimes be caused by a simple connection issue. One helpful step is to test the outlet by plugging in another small appliance to confirm the outlet is active. If the outlet is working, try unplugging the microwave for 30 seconds and plugging it back in to refresh the internal control board. For more guidance, visit https://www.lg.com/us/support/help-library/lg-microwave-oven-troubleshooting-no-power-issue--1429709038316. We’d like to take a closer look and help you move forward with the right next steps.

Good microwave bad glass door design
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Was a good microwave and happy with it for 2 months but beware that there is glass on the front door that is not protected and very vulnerable to a chip and then glass disintegrates making microwave useless. Best Buy would not honor money back or exchange because bumping it and chipping was out fault. Anyone could bump this with anything and it will chip and fail. Out $140 and protection plan. Best took for recycling at least. All other microwaves have the front glass protected from bumps and items falling.

Takes forever to hear things up
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It looks good. That’s about it. This microwave seems to take longer to cook everything than even a 1000 watt oven takes. Food is always cold, needs to go back in. Other things get cold waiting. Wish I hadn’t bought this. Want to go back to my old LG.

Immediately fried itself
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.had high hopes for this product, but unfortunately, it failed me right from the start. As soon as I started using it, it essentially fried itself and became completely non-functional. Despite following all the setup instructions carefully, it just didn’t work as intended. This was a disappointing experience, and I cannot, in good conscience, recommend this product to anyone. Save yourself the frustration and look for a more reliable alternative

Posted .Hi there. Thank you for sharing your experience with us. We understand your situation since you received a product that doesn’t work as expected, especially when you were looking forward to using the LG 0.9 Cu. Ft. Countertop Microwave (MSER0990S). We’d like to help resolve this issue for you.
If the microwave became non-functional immediately after use, it’s possible that there may have been an electrical issue or a malfunction with the unit. We recommend starting with a few troubleshooting steps:
Check the power source: Make sure the microwave is plugged into a working outlet, and confirm that the outlet is not tripped by a circuit breaker.
Reset the microwave: Unplug the microwave for about 1 minute and then plug it back in to reset it.
If the microwave remains non-functional after these steps, we suggest contacting us directly through @LGUSSupport on social media so we can assist with scheduling a technician visit or discuss your options for repair or replacement.

Buyer's remorse
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Sorry I bought it! The sound of the door opening and closing is unusually loud. The "child safety" feature is annoying to fix. Contains far less options than the much less expensive Insignia Microwave this is replacing.

Poor quality
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I recently purchased a Samsung microwave from Best Buy, and I’m extremely disappointed. The unit arrived dirty and covered in dents, making it clear that it was refurbished—despite being sold as new. This is completely unacceptable. Best Buy should not be allowed to sell used or damaged products without properly disclosing it to customers. I expected a brand-new appliance, not something that looks like it came from a scratch-and-dent sale. Will definitely think twice before shopping here again! 1/5 stars.
