SERVICE PROCEDURES AND ADJUSTMENTS
OVEN THERMOSTAT
CALIBRATION
1.
Place a temperature tester probe in the
geometric center of the oven.
2.
Set the infinite switch (1, Fig. 33) for the top oven
element to OFF during oven thermostat
calibration.
3.
Set the thermostat (2, Fig. 33) to 350°F.
4.
Allow the thermostat to cycle three times.
5.
Note the tester reading when the oven indicator
light (3, Fig. 33) turns ON and OFF.
Fig. 33
6.
Add these two temperatures together, then
divide the sum by 2 to obtain an average
temperature.
A.
If the average temperature is within 25°F of
the set temperature, the thermostat is
calibrated.
B.
If the average temperature is not within 25°F
of the set temperature:
1)
Remove thermostat knob. Maintain
thermostat setting during removal.
2)
Hold thermostat stem to prevent
movement. Insert a flathead
screwdriver into thermostat stem (1,
Fig. 34) until it reaches the calibration
screw.
Fig. 34
3)
Turn adjustment screw clockwise to
increase and counterclockwise to
decrease temperature.
NOTE:
A 1/4 turn equals 35°F change.
7.
Replace knob and repeat steps 4 to 6 until
average temperature is within 25°F of set
temperature.
8.
Reseal adjustment screw to prevent movement.
9.
If thermostat cannot be calibrated, replace
thermostat as outlined under OVEN
THERMOSTAT.
GRIDDLE THERMOSTAT
CALIBRATION
1.
Clean temperature test area on griddle surface
then place temperature tester surface mount
probe at that location. See table for proper testing
locations according to griddle size.
NOTE:
This procedure will need to be performed for
each testing location on the 24" and 36" griddles.
Griddle Size
Distance(s) From Left
Edge of Griddle
12"
6"

6", 18"
36"
6", 18", 30"
NOTE:
All readings taken 12" from front of griddle.
2.
Set thermostat to a temperature above 300°F.
3.
Allow thermostat to cycle three times.
