Clock/Timmer stopped working

First I disconnected all power sources. I removed the two clock buttons and the clock/timer switch from the front of the stove. I then removed the back panel from the stove by removing 4 screws holding the panel. This I found was not necessary. The clock was accessable from the front of the stove. This access from the back did allow me to do much needed cleaning from the back side. The front glass insert is held in place by 2 srews. After removing glass plate the clock is easily accessable. Removed two screws holding the clock in place, disconnected the two wires that supply the power to the clock, attached wires to the new clock, screwed the clock body back into the frame of the stove, and replaced the front glass panel.
