Electric Thermostat - Garland G Series Technical Reference Manual

1. Turn all griddle temperature control dials to 350°F
(177°C). In order to allow the temperature to stabilize,
the controls must be allowed to cycle three times before
taking a test reading.
2. Check the temperature reading when the control cuts
down to by-pass by placing the sensor firmly on the
griddle surfaces directly above the sensing bulb of
the control. Reading of the test instrument should be
between 335°F (168°C) and 365°F (185°C).
3. If the dial setting does not agree with the test instrument
reading within the above limits, re-calibrate as follows:

Thermostat Operation
It is normal for a hydraulic thermostat to cycle with a
temperature differential of 45° to 50°. If the thermostat is
cycling beyond the 15° tolerances above or below the set
point and the appliance is under warranty, re-calibrate the
thermostat or if not under warranty, consult the owner for
proper action. If the thermostat is out of calibration more
than 50°, it will not likely hold an attempt of re-calibration.
We suggest that the thermostat be replaced.

4. Remove the dial making sure the setting is not disturbed.
5. Each division mark on the calibration plate equals 15°F.
With a screw driver, turn the calibration screw clock-wise
(toward LOW) to reduce the temperature, or counter-
clockwise (toward HIGH) to increase the temperature.
Example – The dial setting is at the 350°F mark. The test
instrument is reading 380°F. Turn the calibration screw
clockwise (toward LOW) two divisions.
6. Replace the dial, turning the dial to the "OFF" position.
7. Repeat steps 1 through 3 to make sure the correct
adjustment has been made.

Oven thermostat
1 Place the thermocouple of the test instrument in the
center of the oven.
2. Turn the oven temperature control dial to 400°F. In order
to allow the oven temperature to stabilize, the oven
control must be allowed to cycle twice before taking a
test reading.
3 Check the temperature reading just when the control
cycles "OFF" as indicated by the cycling pilot lamp. If the
temperature dose not read within 15° of the dial setting,
re-calibrate as follows:
