MAKE SURE ALL POWER TO THE UNIT IS OFF. FAILURE TO DO SO MAY CAUSE
SEVERE EQUIPMENT DAMAGE OR PERSONAL INJURY!
A. Remove the Knob of the defective Timer by pulling it straight out from the face of the Control
Access Panel.
B. Remove the two mounting screws from the Oven Control Access Panel [73] and gently pull the
Control Access Panel toward you.
C. Remove the two screws securing the Timer [24 or 36] to the Control Access Panel and pull the
Timer out from the back of the panel.
D. Label and disconnect the Timer wiring, OR disconnect the wires one at a time and transfer them
to the same location on the replacement Timer. Terminal "6" on back of the Timer should be
connected to the Oven Power Switch [21] with a black wire. Terminal "4" on back of the Timer
should be connected to a terminal on 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 Access Panel and secure it in
place with the two mounting screws.
F. Replace the Oven Control Access Panel and secure it in place with the two mounting screws.
Be careful not to pull or pinch any wires when installing the panel. Install the Timer Knob by
pushing it onto the end of the Timer Shaft.
G. Restore electrical power to the unit. Check the Timer by setting it for any time over five minutes
and letting it run down. The Buzzer should sound when the Timer reaches "0".
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.
