I also had a similar problem with my Sears Craftsman garage door opener. While Sears said the part may be covered by warranty, it would cost $65 for them to get it done. I am considering filing a class action lawsuit against Sears and Craftsman. If you would like more information on joining the class, please email a summary of your experience with Sears and/or the garage door opener, along with your contact information: name, tele. no., e-mail address.
