I have had my King sized heated blanket for ~ 3 yrs. Actually this is my 3rd winter I will be using it or not. 1st year loved it, worked great, 2nd yr I felt as if all wires/coils were not heating, maybe just down by my feet, just took it out of closet and does not work at all!!
this is my 3rd Sunbeam heated blanket with same issue, my  husband if beyond angry for me buying another one but price point has been affordable, now I know why, he threw out the cord but I kept the blanket, it's a blanket but I did not need another blanket, i need a heated one!  I have searched all over internet for replacement cord thinking that might be the issue to  no avail. The blanket is only used seasonally. I do not recommend this product. I will be calling Sunbeam for options. Ridiculous to have to buy a blanket each winter.
