2) If the thermocouple reading is lower
than set point temperature, press the
up arrow key and enter a positive
offset value that is equal to the
number of degrees below the 5°F
tolerance.
3) Exit the setup mode.
7. Allow the oven to cycle at least two times
between adjustments.
A. If the temperature variance still differs
more than 5°F from the set point, verify the
correct calibration offset value was entered
and retained.
1) Adjust the calibration offset value as
outlined in step 6, until the cycling
temperature is within tolerance.
B. If the above adjustment cannot be
obtained, replace the computer control and
check for proper operation.
ELECTRICAL OPERATION
COMPONENT FUNCTION
Power Switch (S1) ............. Determines the mode of operation; ON, OFF, or OVEN COOL.
Oven Light Switch (S2) ......... Controls the oven cavity lights.
Fan Speed Switch Hi/Low (S3) . . . Controls blower motor speed between Hi and Low settings. Available on
standard models WKG/WKGX or WKGD/WKGDX. On models with the
ROAST & HOLD option (S3) becomes the Function Switch.
Function Switch (S3) ........... Selects the cooking mode of the oven between Normal ROAST or ROAST
& HOLD and is used in conjunction with the ROAST & HOLD timer during
ROAST & HOLD cooking. The selected mode also determines the fixed
blower speed of Hi for Normal ROAST and Low for ROAST & HOLD. In
ROAST & HOLD mode only, energizes the hold relay (R2). Available on
models with ROAST & HOLD option only. On Standard models (S3)
becomes the Function Switch.
Buzzer ....................... Signals the end of a Normal ROAST cycle (normal cooking) when time
expires on the Normal ROAST timer.
Normal Roast Timer ............ Counts the ROAST time (normal cooking) of the product and signals the
buzzer at the end of the cycle. On ROAST & HOLD models only, when the
function switch (S3) is set to Normal ROAST, this timer is used.
Roast & Hold Timer ............ When the function switch (S3) is set to ROAST & HOLD, this timer must
used for ROAST & HOLD cooking. When the ROAST (then hold) time
expires and the function switch is set to ROAST & HOLD, this timer is used
to transfer control of the oven temperature to the Hold thermostat. Available
on models with Roast & Hold option only.
Door Switch .................. Allows the oven to operate when the doors are closed but stops the oven
from operating when the doors are opened.
