THERMOSTAT

WIRING CONFIGURATION

FRONT VIEW

The thermostat is a solid state control. The thermostat supplies power to the burner solenoid valves and indicator lights when turned on or until the temperature setpoint is reached.

Disconnect the electrical power and follow lockout / tagout procedures

THERMOSTAT TROUBLESHOOTING

SYMPTOM – BURNER WILL NOT COME ON

1.Check for loose or excessively greasy/dirty connections at thermostat terminals

2.Check that thermostat is set higher than griddle plate surface temperature.

A.Check for 120 voltage going to L1 terminal on thermostat

B.If no voltage, check wiring and power switch.

3.Check safety ignition module.

4.Check for resistance (approx. 50 Ω) from L2 wire to ground when safety circuit should be made.

A.If no resistance, check that pilot is lit and check safety ignition module.

SYMPTOM – GRIDDLE SURFACE TEMPERATURE IS MORE THAN ±5°F OF THERMOSTAT SET POINT

1.Ensure that you are using a high quality, calibrated surface temperature measuring device.

A.Do not use an infrared thermometer – these are highly inaccurate on a griddle plate.

B.Refer to instructions on page 8 for proper placement of probe and method.

2.Check that burners are properly adjusted.

3.Check that burner valves are operating correctly.

4.Check that there are no burner orifice obstructions

5.Check that the high temp. thermostat probe wire insulation is completely covering the wire. If you have found no problems in steps 1 – 5, proceed page 9 for calibration instructions.

6.If thermostat will not calibrate after all previous steps – replace thermostat.
