Checking the Griddle Plate Temperatures
Use a surface probe such as the one pictured below to check the griddle temperatures. Locate the
probe on the griddle plate just above each thermostat sensing bulb at the center of each burner.
The temperatures should fluctuate between 360° and 390° when the thermostat knob is set to
375°F. The temperature may overshoot at first but should stabilize after the thermostat has cycled
on and off about three or four times. The burners will turn off at about 16 to 18 minutes after turning
on. They will stay off about 10 minutes and then relight and come on for about 5 minutes. This on
and off time is the typical cycle at the 375°F setting.
Calibrating the Snap-action Thermostats (ONLY BY QUALIFIED SERVICERS)
Remove the thermostat knob by pulling it straight out. The slotted stem into which the knob inserts into has a
screw directly at the center. It has been factory sealed to a preset position with a drop of epoxy. If it has been
determined that after several cycles the griddle temperature is not holding the range per test above, break the
epoxy seal and adjust per below.
On
JGTS
models, ½ turn CCW will increase temperature approximately 40°F.
180 arc degrees = 40°F
90 arc degrees = 20°F
45 arc degrees = 10°F
221/2 arc degrees = 5°F
