The problem with 616,000 A.O. Smith Ultra-Low NOx water heaters, sold under seven brand names including Kenmore and Whirlpool, isn’t that they don’t heat water.
The problem, as stated in the U.S. Consumer Product Safety Commission recall notice, is “The water heater’s gas burner screen develops tears. The water heater’s burner can then create excess radiant heat, posing a fire hazard if the water heater is installed directly on a wood or other combustible floor.”
And this has happened six times, the notice states. Which is why those with the recalled water heaters are asked to turn them off and contact A.O. Smith for a free repair.
To see if a water heater is included in this recall, check the serial number, which is on the data plate next to the gas control valve. Serial numbers with the first four digits between 1115 and 1631 are included. To double check, go to www.waterheaterrecall.com and put in the model and serial number.
