A:Answer Hello Lily - this is Nancy at GE. We are sorry to hear that the "Locked" function keeps flashing on your control panel, and I'm happy to help you. You may have pressed a self-clean function. We recommend to disconnect power to the range at the main power supply for a couple of minutes and then restore power. If this does not clear the function, then we recommend contacting the GE Consumer Service to schedule an appointment. They can be reached at 1.800.432.2737, Mon. - Fri., 7:00 am to 10:00 pm, and Sat. - Sun., 8:00 am to 6:00 pm, EST. You may also schedule service online at: http://www.geappliances.com/service_and_support/service/ I hope this helps!
