I finally found the problem. i got into the service menu once and change a couple of settings. i call sears tech line and they told me the same, so i look over the net and found a site that tells me how to go back into the technicians menu and now everything went back to normal. they wont tell you how to go in these menus when you call, they rather let you spend hundreds of bucks to repair a minor problem that you can fix yourself!!!
