SERVICE PROCEDURES AND ADJUSTMENTS
Certain procedures in this section require electrical test or measurements while power is
applied to the machine. Exercise extreme caution at all times. If test points are not easily accessible,
disconnect power and follow lockout / tagout procedures, attach test equipment and reapply power to
test.
OVEN THERMOSTAT
CALIBRATION
1.
Place a temperature tester probe in the
geometric center of the oven.
2.
Set the thermostat to 350°F.
3.
Allow the thermostat to cycle three times.
4.
Note the tester reading when the oven indicator
light turns ON and OFF.
NOTE:
If the difference between the ON and OFF
temperature is greater than 25°F, replace the
thermostat.
5.
Add these two temperatures together, then
divide the sum by 2 to obtain an average
temperature.
A.
If the average temperature is within 10°F of
the set temperature, the thermostat is
calibrated.
B.
If the average temperature is not within
10°F of the set temperature:
1)

2)
Insert a flathead screwdriver into
thermostat dial stem until it reaches

3)
Turn adjustment screw CW to
increase and CCW to decrease
temperature.
