Anyone there willing to troubleshoot? I have a three year old Dacor micro model DCM24S. Pressing the button will not open the door. During the past few months it would periodically give us some trouble; however, it bounced back. Now the button has no resistance when depressed. One video suggests silicon spray, but the problem may need a part. (Spring,etc.) Any clues? I am very good at home repair, yet I may need someone to service the unit. Thanks. - Chris
