Incident Overview

On July 18, 2025, a consumer who purchased a Ninja DT501 Prestige XL Air Fryer & Countertop Oven from Amazon reported that the device began overheating severely and developed burn marks on its back. After contacting Ninja support, a replacement unit was sent. However, the replacement also exhibited overheating and burn marks, along with a loose internal fan blade. The consumer provided photos to Ninja documenting the damage and safety concerns.

Ninja sent a third replacement unit, which again showed burn marks on the back. The excessive heat from the unit also caused damage to the consumer's countertop backsplash. The consumer reported that this repeated defect across multiple units raises serious safety concerns, including the risk of fire and property damage. The incident is documented in CPSC SaferProducts report ID 5917332 (https://www.saferproducts.gov/PublicSearch/Detail?ReportId=5917332).

Safety Concerns

Immediate Dangers: The reported overheating and burn marks indicate a risk of fire during use. If the internal components continue to overheat, they could ignite nearby flammable materials, such as kitchen towels or cabinets, posing an immediate threat to life and property.

Long-Term Risks: Repeated overheating across multiple units suggests a systemic design flaw that may not be resolved by simple replacement. Continued use could lead to cumulative thermal damage, increasing the likelihood of a catastrophic failure such as an electrical fire.

Property Damage Potential: The consumer reported that the heat damaged a countertop backsplash. This shows that even if the device does not catch fire, the heat emitted can cause permanent damage to surrounding surfaces, including countertops, walls, and appliances.

Warning Signs: The presence of burn marks on the back of the unit and a loose internal fan blade are clear warning signs that the device is malfunctioning. A loose fan blade can indicate mechanical failure, potentially leading to blade detachment or further overheating due to reduced cooling efficiency.
