We loosened two screws, pulled the old one out, and put the new one in. It took five minutes or so. The so-called repair man who supposedly fixed it twice after my husband took the stove to him is in deep trouble with us. We live way out of town, and we took it to him as a courtesy. He never worked on it either time and charged us. We are going to rely on the internet instructions and repair our own from now on.
