Thousands of thermostats installed in homes across the country are now being recalled because they may pose a fire hazard. The Emerson Company says contact between the thermostat wires and household line voltage of the Sensi Wi Fi thermostats can damage the thermostat and cause a fire. So far the firm has received eight reports of burn damage to the thermostat, involving minor property damage. No injuries have been reported. The thermostats are white with an LCD screen and have the name “Emerson” printed on the front. The date code on the back will be between 1416 and 1536.
