The U.S. Consumer Product Safety Commission, in cooperation with OJ Electronics of Chicago, announced a voluntary recall of about 30,000 208-volt and 240-volt thermostats found in under-floor radiant heating systems.

The recalled thermostat’s floor sensor or its cable can be damaged from cutting, drilling or nailing. This poses a risk of electric shock to consumers if the power supply is not disconnected.

No incidents or injuries have been reported.

The recall involves thermostats that have a built-in GFCI and are designed for use in under-floor heating systems. Thermostats included in the recall are connected to 208-volt or 240-volt power supplies (120V units are not included in the recall). They were sold under the brand names of Canisol, Danfoss, Elektra, Momento, OJ Microline, Raychem, Thermosoft, Warmly Yours and Warmup. The brand name is located on the front of the thermostat.

The thermostats were sold at various home improvement stores, tile shops and other retail shops nationwide from January 2004 through December 2008 for between $150 and $200.

Consumers should not cut, drill or nail into the heated floor, and contact the manufacturer to arrange for a free in-home repair.

For additional information, contact OJ Electronics at 800/380-6940 between 9 a.m. and 5 p.m. CT Monday through Friday or visit the firm’s Web site at www.ojelectronics.com.
