June 11, 2026 — A consumer has reported an incident involving an LG LWC3063ST combo microwave oven, where the appliance’s glass door spontaneously cracked and broke into pieces during operation. The incident raises concerns about the safety and durability of the microwave’s components.
Product Details
Incident Overview
On May 25, 2026, a consumer reported that the glass on their LG combo Microwave Oven, model LWC3063ST, failed during cooking. The glass reportedly cracked and broke into multiple pieces without warning while the appliance was in use. The microwave oven was purchased in October 2021 and installed shortly thereafter, on October 18, 2021, indicating that the unit was approximately 4.5 years old at the time of the incident. The report specifies the sudden and unexpected nature of the glass failure while the unit was actively performing its cooking function.
Safety Concerns
The sudden failure of a microwave oven’s glass door presents several significant safety concerns:
- Immediate Dangers: Exploding or shattering glass can cause severe lacerations, cuts, and puncture wounds to anyone nearby. Hot food or liquids inside the microwave could also be expelled, leading to burns. The sudden noise and unexpected nature of the event could also cause shock or injury from involuntary reactions.
- Long-Term Risks: If the structural integrity of the microwave door is compromised, there’s a potential risk of microwave radiation leakage if the unit continues to be used. While the reported incident specifies glass failure, further damage to the door’s seal or other components could occur.
- Who Might Be Affected: Consumers, particularly those in the immediate vicinity of the microwave, including children and pets, are at risk of injury from flying glass shards. Individuals retrieving food from the microwave or simply present in the kitchen area could be affected.
- Property Damage Potential: Beyond personal injury, shattered glass can damage kitchen surfaces, flooring, and other nearby appliances. The contents being cooked could also be ruined or spill, creating a mess and potential fire hazard if spilled onto hot components.
What Consumers Should Do
Consumers who own an LG LWC3063ST combo microwave oven or similar models should take the following precautions:
- Immediate Steps to Take: If your microwave oven’s glass door breaks or shows signs of cracking, immediately cease use, unplug the appliance, and ensure no one touches the damaged area. Carefully clean up any broken glass using thick gloves and appropriate protective gear. Do not attempt to operate the microwave with a damaged door.
- How to Check if They Own the Affected Product: Locate the model number on your LG microwave oven, typically found on a label inside the door frame or on the back of the unit. Compare it to the LWC3063ST model mentioned in this report.
- Prevention Measures: Regularly inspect your microwave door for any signs of cracks, chips, or damage to the glass or seals. Avoid slamming the microwave door and ensure proper ventilation around the appliance. If you notice any issues, stop using the microwave and contact the manufacturer for guidance.
- Reporting Procedures: If you experience a similar incident with your LG microwave or any other consumer product, report it to the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov. This helps the CPSC gather data and identify potential patterns of defects.
