The thermostats are made by White-Rodgers, but some have different brand names printed on the front, including ComfortSentry, DICO, Emerson, Frigidaire, Maytag, Nutone, Partners Choice, Rheem, Ruud, Unico, Water Furnace, Westinghouse and Zonefirst.
About 740,000 of the thermostats were sold in the United States and 403,000 were sold in Canada from January 2006 to December 2013 through hardware stores and heating and air conditioning companies.
There have been seven reports of burn damage to the thermostat, with two involving minor property damage, the U.S. Consumer Product Safety Commission said. No injuries have been reported.
Recalled thermostats don't have a battery icon on the left side of its blue lighted screen, the CPSC said. Customers should call White-Rodgers at 888-624-1901 or register at www.regcen.com/1f8recall/ .
White-Rodgers, based in St. Louis, Mo., is a division of Emerson Electric Co. The thermostats were made in China.
