The U.S. Consumer Product Safety Commission and Frigidaire has announced a recall of about 7,500 Kenmore Wall Ovens. Gas can build in the oven cavity during extended broiling and escape when the oven door is opened, posing a significant fire and burn hazard. Sixteen incidents involving burns to the hands, face and singed hair have been reported. This recall involves Kenmore 24-inch-wide gas and propane, wall-mounted ovens in white, black, bisque and stainless steel. The model and serial numbers can be found on the frame on the left side of the oven cavity. The recalled ovens have models numbers 790.30472400, 790.30473400, 790.30474400, 790.30479400, and the serial numbers range from NF401xxxxx through NF610xxxxx. The ovens were sold nationwide from September 2004 through October 2007. Consumers should stop using the "broil" feature on the oven immediately and contact Sears at (800) 479-6408 for a free repair.
