A broken motor mount can cause overheating that could led to a fire, the Consumer Product Safety Commission said.
The recall involves Kenmore oscillating fan heaters with model number 127.90914310.
The fan heaters are gray and white, measuring 12 inches tall and 9 inches wide. They have two dials on the top, one to regulate temperature and one to regulate fan speed.
Kenmore is printed on the front bottom of the fan heaters.
The retailers have received seven reports of fans smoking or catching fire. Two of the reports included descriptions of injuries, the agency said.
The fans were imported from China and sold nationwide from September 2013 through November 2013 for around $37.
They were imported by Sears Holdings of Hoffman Estates, Ill.
Consumers were advise to turn off and unplug the fans and return them to any Kmart or Sears store for a full refund.
