D. Label and disconnect the Timer wiring, OR disconnect the wires one at a time and transfer them to
the identical location on the replacement Timer. Terminal "4" on the Timer should be connected to
the Oven Power Switch [21]. Terminal "6" on the Timer should be connected to one side of the
appropriate Buzzer Alarm [16]. Make sure all connections are clean and tight.
E. Position the replacement Timer on the back side of the Control Panel and secure it in place with
the two mounting screws. Install the Timer Knob by pushing it onto the end of the Timer Shaft.
F. Replace the Control Panel on the face of the unit, being careful not to pull or pinch any wires
while installing the panel.
G. Restore electrical power to the unit. Check the Timer by setting it for any time over five minutes

NOTE: If the Buzzer sounds BEFORE the Timer reaches "0" or AFTER the Timer runs past "0"
the Timer Knob can be adjusted by loosening the two Phillips-head screws on the back of the
Knob, repositioning the clear index dial on the Knob, and tightening the screws.
