July 14, 2026 — A recent incident report details a consumer’s experience with an LG MSER2090S countertop microwave oven whose glass door unexpectedly shattered while the appliance was not in use. The incident highlights potential safety concerns regarding glass integrity in household appliances and raises questions about manufacturer and retailer warranty coverage for such events.
Product Details
Product: LG MSER2090S
Incident Overview
On October 17, 2025, a consumer purchased an LG MSER2090S countertop microwave oven from Lowe’s in West Bridgewater, Massachusetts. Approximately seven months later, on May 29, 2026, the owner reported hearing a “bang” from their kitchen. Upon investigation, they discovered that the top section of the microwave oven’s glass door was broken. Further inspection revealed that the glass had completely shattered *inside* the protective panes, with small pieces of glass beginning to fall out. Crucially, the microwave was not in operation at the time of the incident.
Following the event, the consumer contacted LG on May 30, 2026, and provided photographs of the damaged door. On June 1, LG reportedly informed the consumer that the damage was not covered under warranty, classifying “glass damage” as “cosmetic,” and advised them to contact Lowe’s. Subsequently, on June 8, the consumer contacted Lowe’s, only to be informed that the damage was also not covered under their extended warranty, again citing “cosmetic” glass damage, and directing them back to LG. The consumer asserts that the damage is not merely cosmetic but is both functional and dangerous, as shards of glass are falling from the appliance.
Safety Concerns
The spontaneous shattering of an appliance’s glass component, particularly while idle, presents several significant safety concerns:
- Immediate Dangers: The primary and most immediate danger is the risk of injury from flying or falling glass shards. These pieces can cause severe cuts, lacerations, and puncture wounds to anyone nearby, including adults, children, and pets. Even after the initial incident, small pieces of glass can continue to fall, posing an ongoing hazard.
- Long-Term Risks: If glass fragments are not fully contained or cleaned, they could inadvertently contaminate food preparation surfaces or food itself, leading to ingestion risks. The structural integrity of the microwave door may also be compromised, potentially affecting its ability to contain microwaves safely during operation, though the consumer reported the microwave was not in use.
- Who Might Be Affected: Anyone in the vicinity of the microwave at the time of the incident, or anyone attempting to handle or clean the appliance afterwards, is at risk. This includes family members, guests, and pets, with children being particularly vulnerable due to their height and natural curiosity.
- Property Damage Potential: Beyond personal injury, falling glass shards could scratch or damage countertops, flooring, and other kitchen surfaces. The microwave itself becomes unusable, representing a financial loss.
What Consumers Should Do
If you own an LG MSER2090S microwave or a similar model and experience a similar incident, here’s what you should do:
- Immediate Steps:
- Do not use the microwave. Unplug the appliance immediately to prevent any further potential hazards.
- Keep a safe distance. Avoid touching the broken glass.
- Document the incident. Take clear photographs and videos of the shattered door, the surrounding area, and any fallen glass pieces. This documentation will be crucial for reporting and potential claims.
- How to Check Your Product: Verify your microwave’s model number, typically found on a label inside the door frame or on the back of the unit, to determine if you own an LG MSER2090S or a similar model.
- Prevention Measures: While incidents like this are often unforeseen, ensuring proper installation and avoiding impacts or extreme temperature changes around the appliance may help prevent damage. However, in this case, the incident occurred while the microwave was idle, suggesting a potential inherent defect.
- Reporting Procedures:
- Contact the manufacturer and retailer: As the consumer in this report did, contact both LG Electronics, USA and Lowe’s to report the issue and inquire about warranty coverage or product replacement. Be prepared to provide your incident documentation.
- Report to the CPSC: File a report with the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov. Your report helps the CPSC monitor product safety, identify potential widespread issues, and initiate investigations or recalls.
Manufacturer’s Response
As of June 29, 2026, LG Electronics, USA has provided the following general statement regarding their products: “LG manufactures this microwave to meet or exceed all relevant standards including UL923. Our process not only rigorously tests to insure the quality of product leaving our factory, but we also carefully monitor how our products perform in use.

This response emphasizes LG’s commitment to quality and safety standards but does not specifically address the individual consumer’s warranty claim or the specific incident of glass shattering while the unit was idle.
