Oven Temperature Calibration - Viking veso165 Service Book

Electric oven calibration using the EATON
thermostat. The adjustment screw is located
on the bottom of the thermostat ( 3/32 Allen
head screw ). Each 1/4 turn is equal to approx-
imately 35 degrees. COUNTERCLOCKWISE
adjustment will DECREASE the temperature.
CLOCKWISE adjustment will INCREASE the
temperature.
If the oven temperature is off more then 50 degrees
you should change the thermostat.
REMEMBER WHEN YOU CHANGE THE OVEN
TEMPERATURE YOU ARE ALSO CHANGING
THE SELF-CLEAN TEMPERATURE. (As a rule
of thumb you should only calibrate the thermostat only
to increase the oven temperature.)
A. Center Oven Temperature Check: Before
turning the oven on, check the thermostat
sensor bulb position. It should be straight, no
kinks and secured in the mounting clips.
B. Place the oven rack in the center of the oven.
C. Place the thermocouple lead in the center of the
rack and close the door. Avoid touching metal
with the thermocouple junction.
D. Set the selector switch to " BAKE" and the
temperature dial to 350º.
NOTE: Do not overshoot the 350* mark. When
you go beyond 350º, return the control to the
lowest setting and reset to 350º.
E. Cycle the oven 5 times ; Average the 3rd, 4th,
and 5th cycles. The temperature is acceptable if
the average is 350º ± 25 º.

1. Check air shutter adjustment: sharp blue
flame, no yellow tipping.
2. Check orifice hood adjustment.
