February 23, 2026 — An LG slide-in gas range (model ltgl6937f) has been red-tagged by the gas utility after emitting over 500 parts per million of carbon monoxide during normal operation, leading to a household member’s emergency room evaluation. This incident highlights a severe product safety defect indicating incomplete combustion, rendering the new appliance unsafe for use and prompting its removal from service.
Product Details
Incident Overview
This serious carbon monoxide (CO) hazard was first reported on January 29, 2026, concerning an LG slide-in gas range (model ltgl6937f) manufactured in October 2025 and installed in a residential kitchen on December 7, 2025.
Prior to formal CO testing, the household experienced abnormal operation, including extreme and variable oven temperature deviations of approximately ±100°F during normal use. Despite reporting these issues to LG and requesting service, two separate LG representatives reportedly advised the consumer to continue using the appliance.
Subsequently, a household member experienced acute symptoms consistent with carbon monoxide exposure and required emergency room evaluation. Following this medical emergency, an investigation revealed dangerous carbon monoxide emissions from the range. The gas utility, TECO (People’s Gas), measured CO levels exceeding 500 parts per million (ppm) during normal operation, immediately red-tagging the appliance as unsafe for use and removing it from service.
The elevated CO levels indicate severe incomplete combustion, posing a life-threatening risk to occupants. The appliance has not been used since being red-tagged and has been moved to the garage for preservation in its current condition. A replacement range has been purchased to restore kitchen functionality and resume normal household activities, including a home-based cottage food business operation, which was interrupted by the incident. Documentation, including utility reports, model/serial numbers, and photographs, is available.
Safety Concerns
The incident involving the LG ltgl6937f gas range raises critical safety concerns:
- Immediate Dangers: Carbon monoxide is a colorless, odorless, and tasteless gas, making it extremely difficult to detect without proper equipment. Levels exceeding 500 ppm are highly dangerous and can cause severe poisoning, leading to brain damage, cardiac arrest, and death in a short period. Symptoms can include headache, dizziness, nausea, vomiting, confusion, weakness, and loss of consciousness. The fact that a household member required emergency room evaluation underscores the immediate and life-threatening nature of the defect.
- Life-Threatening Risk: Incomplete combustion, as indicated by high CO emissions, means the appliance is not burning gas efficiently and is releasing a deadly byproduct directly into the living space. This is a severe design or manufacturing defect.
- Ignored Warning Signs: The report highlights that the consumer initially experienced temperature instability and was advised by the manufacturer to continue using the appliance. This illustrates the danger of disregarding operational anomalies, especially in gas appliances, and the potential for customer service advice to inadvertently exacerbate a safety risk if not adequately informed.
- Who Might Be Affected: Any occupants within the home are at risk of CO poisoning, with children, the elderly, pregnant individuals, and those with pre-existing heart or respiratory conditions being particularly vulnerable. Pets are also highly susceptible to CO poisoning.
- Property Damage Potential: While no structural damage to the home was reported in this specific incident, the appliance itself was rendered unsafe and unusable, resulting in a complete loss of its intended function. The loss of use of the kitchen significantly disrupted normal household activities and a home-based business, incurring additional costs for a replacement appliance and potential economic losses.
What Consumers Should Do
Consumers who own an LG ltgl6937f gas range or any gas appliance should take the following precautions:
- Immediate Action if CO Suspected: If you or anyone in your household experiences symptoms of carbon monoxide poisoning (headache, dizziness, nausea, confusion) or if your carbon monoxide detector alarms, immediately evacuate everyone from the home, call 911 or your local emergency services, and do not re-enter until the home has been deemed safe by professionals.
- Check Your Appliance: Verify if you own an LG slide-in gas range, specifically model ltgl6937f, or any gas range manufactured by LG Electronics, USA. Check the model and serial numbers, typically found on a label around the oven door frame, back, or bottom of the unit.
- Install and Maintain CO Detectors: Ensure you have working carbon monoxide detectors installed on every level of your home, especially near sleeping areas. Test them regularly and replace batteries as recommended by the manufacturer.
- Do Not Ignore Malfunctions: If your gas range or any gas appliance exhibits abnormal operation, such as unusual odors, yellow or orange flames (instead of blue), soot buildup, or inconsistent temperatures, cease use immediately. Contact a qualified appliance technician or your gas utility for inspection. Do not continue using an appliance that you suspect is malfunctioning, even if advised otherwise by untrained personnel.
- Professional Installation and Inspection: Always ensure gas appliances are installed by a certified professional. Consider scheduling annual inspections of all gas appliances by a qualified technician to ensure they are operating safely and efficiently.
- Report Incidents: If you experience a similar incident or suspect a defect with your appliance, report it immediately to the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov and to the manufacturer.
