Replacing the electric blanket cord replacement may seem like a daunting task, but with the right tools and materials, it’s doable. First, you’ll need new wires, which you can buy at an electronics store, as well as a screwdriver and electrical tape. It’s important to make sure the new connection is safe to avoid short circuits or fires. If you’re not confident in your skills, it’s best to call in a professional. My experience was this: when the cord broke, I tried to replace it myself, but I connected the wires incorrectly, causing the unit to overheat. After that, I went to a service center, where they fixed it for me.
