January 15, 2026 – A consumer has reported a serious safety incident involving a Cosori Smart Air Fryer/Toaster Oven, model AO-RXB, which was received as a replacement for a previously recalled product. The appliance, barely two years old, escalated from making extremely loud noises to causing electrical sparking and smoke at the outlet when attempts were made to shut it off or unplug it, raising significant fire and electrical shock concerns.
Product Details
Incident Overview
The initial report on December 22, 2025, described a Cosori Smart Air Fryer/Toaster Oven, model AO-RXB, making an “extremely loud noise” sporadically upon startup. The consumer indicated that the only way to stop the noise was to unplug the appliance, expressing fear that the item had the potential to be dangerous. This particular unit was provided as a replacement for a previously recalled Cosori product.
An update on December 30, 2025, revealed a significant escalation of the issue. The loud noise became more frequent and severe, and the appliance could not be shut off using its designated “off” button. Critically, when the consumer attempted to unplug the machine, the outlet began sparking, accompanied by the smell of smoke. The consumer noted that the machine did not fully shut off even after the plug was pulled, indicating a severe and persistent electrical malfunction. This incident caused fear of burns and a potential fire. The appliance is only two years old and is just outside its warranty period. The consumer also highlighted that discussions of this exact model with identical issues are prevalent online, suggesting this may not be an isolated incident.
Safety Concerns
The reported incident with the Cosori Smart Air Fryer/Toaster Oven (AO-RXB) presents several grave safety concerns:
- Immediate Dangers: The most immediate and critical dangers are electrical shock and fire. Sparking at the electrical outlet combined with the smell of smoke is a direct indication of an electrical fault that can lead to severe burns, electrocution, or ignite nearby combustible materials, resulting in a house fire.
- Inability to Power Down: The inability to shut off the appliance using its controls, and the continued electrical disturbance (sparking) even when attempting to unplug, signifies a catastrophic internal failure. This loss of control over a high-power appliance makes it incredibly dangerous to interact with.
- Long-term Risks: If not immediately addressed, such a defect could lead to repeated electrical overloads, damage to the home’s wiring system, and persistent fire hazards. The risk of the fault occurring when the appliance is unattended also significantly increases the fire risk.
- Who Might Be Affected: Anyone using the appliance, children or pets in the vicinity, and anyone occupying the dwelling are at risk of injury or harm from fire or electrical shock.
- Property Damage Potential: A fire originating from an appliance like an air fryer/toaster oven has the potential to cause extensive damage to the kitchen and surrounding areas of a home, including structural damage. Electrical damage to the outlet and internal wiring is also a direct consequence.
What Consumers Should Do
If you own a Cosori Smart Air Fryer/Toaster Oven, model AO-RXB, or any other Cosori appliance that exhibits similar symptoms:
- Discontinue Use Immediately: If your appliance is making unusual noises, sparking, smoking, or cannot be turned off, stop using it immediately.
- Safely Disconnect Power (if possible): If the appliance is *not* currently sparking or smoking, carefully unplug it. If it *is* sparking or smoking, do NOT attempt to unplug it directly, as this could worsen the situation or cause injury. Instead, trip the circuit breaker controlling the outlet the appliance is plugged into. If you are unsure which breaker it is, turn off the main breaker to your home’s power.
- Do Not Re-plug: Under no circumstances should you plug the appliance back in or attempt to use it again if it has exhibited these dangerous symptoms.
- Check Your Model: Verify if you own the Cosori Smart Air Fryer/Toaster Oven model AO-RXB. The model number is typically found on a label on the back or bottom of the unit.
- Report the Incident: File a detailed incident report with the U.S. Consumer Product Safety Commission (CPSC) at www.cpsc.gov.
- Contact the Manufacturer: Reach out to Vesync Group or Cosori customer service to report the issue and inquire about potential remedies or a recall, especially given that this unit was a replacement for a prior recall.
