Consumer Reports has sounded an alarm after investigating a string of disturbing incidents: certain Toshiba-branded microwaves and air fryer–microwave combos have reportedly started running on their own, overheated, and in some cases produced smoke or flames. The findings have prompted safety warnings and raised fresh concerns about kitchen appliance hazards in homes nationwide.
What Consumer Reports discovered about spontaneous operation and fire risk
In June 2026, Consumer Reports published a safety alert after reviewing consumer complaints and incident data. The main problem: some units appear to begin heating without a user pressing any buttons. That can lead to overheating, melting plastics, and even ignition.

CR examined reports submitted to the U.S. Consumer Product Safety Commission and consumer posts on social platforms to build its case. Between January 2023 and April 2026, the organization identified 28 incident reports tied to these microwaves and combo appliances.
Which Toshiba models are called out by Consumer Reports
Consumer Reports named several specific models linked to malfunction reports. If you own one of these, be aware of the issues being reported.
- Air fryer + microwave combos: ML2-EC10SA, ML2-EC10SA(BS), ML2-EC09SA
- Standard countertop microwaves: EM131A5C, EM925A5A-SS
These model numbers came up repeatedly in consumer complaints and online reviews. Listings on retail sites still show many of the devices with high star ratings despite troubling safety anecdotes.
Reports from owners: incidents, social posts, and product reviews
Firsthand accounts shared on Reddit and in Amazon reviews describe unsettling behaviors. Users reported microwaves turning on late at night, running while empty, or powering up with the door open. Several posts claimed sparking or smoke that required unplugging or emergency response.
One reviewer said the appliance began operating with the door ajar. Others recounted smells suggesting melting insulation or scorched plastic. On social feeds, photos and videos fueled peer warnings to avoid certain Toshiba models until the issue is resolved.
Patterns in the complaints
- Appliance activates without user input.
- Heating cycles extend or start unexpectedly.
- Smoke, sparks, or burning odors appear during operation.
- Some incidents reportedly escalated to actual fires.
Manufacturer and regulator reaction so far
Midea, the company that manufactures these Toshiba-branded units, told Consumer Reports it considered the appliances safe while also acknowledging it has been made aware of incidents. Consumer Reports, though, pushed for stronger action.
CR sent a letter to the Acting Chair of the U.S. Consumer Product Safety Commission urging a formal investigation. The nonprofit asked the agency to consider remedies up to and including a recall if hazards are confirmed.
Practical safety moves for people who own these microwaves
Experts advising on the issue stress vigilance. Juan Alberto Arguello, PhD, who leads CR’s product safety testing, recommended several simple steps to reduce risk.
- Watch the appliance while it runs. Do not leave it operating unattended.
- Stop using it if you see smoke or sparks. Unplug immediately and contact the manufacturer.
- Avoid storing items inside the microwave. Objects left in the cavity can melt or catch fire.
- Unplug after use when feasible, especially if you notice unusual noises or smells.
- Check model numbers against the list of implicated units before buying or continued use.
How to stay updated and report problems
Consumers should monitor announcements from Consumer Reports, the CPSC, and the appliance maker for updates. If you experience a malfunction, report it to the CPSC and keep documentation, photos, or videos.
Retail listings may not reflect safety actions immediately. For now, many safety advocates advise caution with the named Toshiba models and stress that any microwave showing signs of failure should be taken out of service until it is inspected or replaced.
