I can understand your dismay when you found out that that part is no longer available through Sears Parts Direct.com. I did a search and couldn't find it either. But I will forward your question to an expert who will investigate the matter further and get back to you. You will hear from them within two business days if not sooner. Until you hear from us, have a nice day.
Thanks for contacting ManageMyLife.com. Sergio, I know how important it is to have parts for your appliances. I also did some research and found it not to be available through any outlets. Due to the age, the part is no longer made. Sorry for any inconvenience.
Please feel free to let me know if you need further assistance.
