Consumers who have griddles with model number XJ-14207 should return them to any Walmart store for a full refund.

The model number can be found on the bottom of the griddle on a label mold.

“Consumers should immediately unplug and stop using the recalled griddles and return them to any Walmart store for a full refund,” the CPSC said.

The home appliance brand is sold exclusively at Walmart in stores and online. The griddle sold for about $20 from July 2015 to December 2015.

About 330,000 units are being recalled.
