CPSC said affected Emerson Sensi WiFi thermostats can be damaged by household line voltage, posing a fire hazard, which can happen during replacement or service of the heating or cooling system. About 15,000 of the thermostats are also being recalled in Canada, CPSC said.
The agency has received at least 8 reports of burn damage to the thermostat with minor property damage, but no injuries. Health Canada has no reports of incidents or injuries.
Affected thermostats were sold under the Emerson brand name from April 2014 to December 2016 at Home Depot, Johnstone, Golden State FC, and HVAC equipment distributors nationwide. The devices have 1 of the following 2 model numbers: 1F86U-42WF or UP500W.
To tell if your thermostat is affected by the recall, take it off the wall and look at the date code on the back side of the unit. If you have a recalled device, you should contact White-Rodgers for a repair or free replacement.
