Test Procedure
F1 - Control malfunction.
F2 - Oven over temperature.
F3 - Open sensor or sensor circuit
F4 - Shorted sensor or sensor circuit
F7 - Shorted input key.
F9 - Door lock or door lock circuitry
malfunction (door unlocked)
FF - Door lock or door lock circuitry
malfunction (door locked)
DOOR - lock status is not sensed
within 90 seconds of energizing door
lock relay.
Press BAKE
Press + slew pad until an oven
temperature greater than 500° shows
on display. Immediately press and
hold BAKE until "00" appears in
display, approximately 5 seconds.
To decrease oven temperature (for a
cooler oven), press - slew pad until
negative numbers appear. Oven can
be adjusted from -5 to -35 degrees lower .
To avoid over adjusting oven move
temperature -5 degrees each time.
To increase oven temperature (for
warmer oven), press + slew pad until
positive numbers appear. Oven can
be adjusted 5 to 35 degrees higher.
To avoid over adjusting oven move
temperature 5 degrees each time.
Press OFF CANCEL. Temperature
Adjustment will be retained even
through a power failure.
Control will automatically cancel any
baking operation and remove all relay
drives 12 hours after the last pad touched.
This is a safety feature that can be used
to prevent children from accidentally
programming the oven. It disables the
electronic oven control. Press and hold
BAKE and BAKE TIME for 5 seconds.
"OFF" will display where the tempera-
ture normally appears. To reactivate the
control press and hold BAKE and BAKE
TIME for 5 seconds. Child lockout feat-
ure must be reset after a power failure.
