Emerson Sensi WiFi Thermostats Recalled for Fire Hazard

house fire fire fighters on roof Emerson Sensi WiFi Thermostats Recalled for Fire HazardU.S. and Canadian authorities are urging the public to check their thermostats after learning of a fire risk associated with Emerson-branded Sensi WiFi thermostats.

The U.S. Product Safety Commission (CPSC) says that approximately 135,000 Emerson thermostats are being recalled in the U.S. because of a defect that could potentially cause a house fire. The Canadian government says an additional 15,546 units of the affected products were sold in Canada.

The wires inside the thermostats covered by the safety recall can contact each other, creating an electrical short that could lead to overheating and fire. The thermostats also can be damaged by household line voltage (120 volts or 240 volts) during service or replacement of a heating or cooling system, posing a fire hazard.

Emerson has received eight reports of fire-related property damage resulting from the defective thermostats. The company is not aware of any injuries associated with the devices.

Consumers can tell if they have a recalled unit by checking to see if the name “Emerson” is displayed on the front of the device top and center above the digital LCD screen. The back of the recalled units will display the model numbers 1F86U-42WF or UP500W and a date code that ranges from 1416 to 1536 — representing the 16th week of 2014 through the 36th week of 2015.

The thermostats are standard white plastic with three buttons below the LCD screen and an up-and-down button to the right of the screen.

UPC codes on product packaging are: 786710549335 and 786710549762.

The CPSC says the thermostats were made in Guangdong, China by Jabil Circuits and imported to the U.S. by White-Rodgers, a division of Emerson Electric Co. of St. Louis, Missouri. They were sold by Johnstone, Home Depot, and Golden State FC stores and heating ventilation and air conditioning (HVAC) equipment distributors nationwide from April 2014 through December 2016.

Anyone with the recalled thermostats should contact White-Rodgers toll-free at 888-847-8742 from 7 a.m. to 6 p.m. CT Monday through Friday for instructions on repair and replacement. Additional information can be found online at
