When I realized I broke the knob I tried to crazy glue and compress it back into form with a vice but it didn't hold. So I went on the internet and found this site which sold parts. I thought I found the correct part and ordered it. When it arrived ( a couple days later ) I realized it was the wrong part. Frustrated , I got on the phone with the site and I spoke to a young lady from Tennessee who spent 30mins helping me find the correct part. But it gets better, when I arrived home the next day, the part was in my mail box! Less then 24 hrs later!!!
