I need to buy a new cord.

Just this morning as I was cooking rice with the use of the rice cooker, I was surprised that the cord of the rice cooker produces smoke that was coming from it. I turned it off and I checked the problem. Oh my...! The cord was overheat. That is why, it produces smoke. The rubber was hot. It gradually smoke and melt. I soon discovered that it overheats. That is why, I need to buy a new cord for my rice cooker. But the problem is where could I purchase one because I remembered that I bought it as a set. I hope that I can find one.
