An electric blanket can keep you warm on a cold winter's night without turning up the thermostat. It can also warm up cold sheets before you hop into bed. Sunbeam is a major manufacturer of electric blankets, and sometimes, the digital display starts flashing or doesn't turn on. On some models, a flashing "FF" will appear. These are signs that you need to reset your blanket. The tag should feature set of reset instructions, but in general, Sunbeam electric blankets are reset in a fashion similar to most electric blankets.
Push the "On/Off" button, and then turn it back on. Resetting may be as simple as that.
Unplug your electric blanket from the electrical socket and check to make sure the cord is plugged in securely at the base of your blanket. Also at this point, check that the blanket appears to be in good repair. Plug it back in to the wall socket and turn the blanket on.
Repeat Step 2 two more times. If your blanket still does not reset, unplug your blanket and call customer service at 800-892-7684 in you're located in the United States or 800-667-8623 in Canada.
