If you can pull the capillary tube and the bulb moves it is not held tight enough against the griddle plate. This will cause variations in the temperature of the griddle surface. If both of these items have been checked and you still have a differential over 75.F then the thermostat is bad replace it. Determine the average temperature Note the temperature for each section of the griddle as the burners ignite. Note the temperature for each section of the griddle as the flame extinguishes. The flame extinguish temperature plus the flame ignition temperature divided by two equals the average temperature. EXAMPLE: Flame extinguished 367.F Flame ignition 341.F 708. / 2 Average temperature = 354.F If the average temperature is within 15.F of the dial marking you probably leave the calibration where it is. If the average temperature is outside of 15.F of the dial setting you will want to calibrate the thermostat. To calibrate a thermostat first remove the knob by pulling it straight off the shaft. Next take a small flat head screw drive and turn the screw inside the shaft, clockwise to decrease, counterclockwise to increase. . turn clockwise will decrease the temperature approximately 24.F. . turn counterclockwise will increase the temperature approximately 24.F. Adjust and re-measure the average temperature until you get the temperature to your desired point. NOTE: avoid making more than . turn at a time. Calibration is not linear and you can get the thermostat significantly out of calibration to a point where it is difficult to reset. If after adjusting the thermostat three times and getting no change in calibration the thermostat is bad. Then replace the thermostat. 9 TROUBLESHOOTING GUIDE PROBLEM POSSIBLE CAUSE Heat does not come on when thermostat is turned on. Thermostat is bad. Pilot burner not lit. Gas valve is bad.
