Query: Great for awhile and then POOF!

I loved this cooker. It was great until the last time I used it and it was just as some others said. The plastic lid melted and I'm still trying to get the stench out of the house. Apparently, it didn't turn off when it was supposed to. Glad I was at home so the house didn't burn down or something! Am so disappointed because I really liked it!
