42 THE CONTROL SYSTEM

Thermocouple – Cook Chamber (Figure 47) Thermocouple – Electrical Compartment (EC)

Type K Thermocouple. Thermocouple measures the temperature of the recirculating impingement airflow. If the display indicates 999ºF/C, the Thermocouple is “open,” resulting in an F7 Fault.

To replace a defective CC Thermocouple:

1.Ensure “Cool Down” process is completed (“Cool Down” message will disappear upon completion) and unplug the oven.

2.Remove Right Side Panel.

3.Pull back insulation where necessary.

4.Replace defective thermocouple with P/N NGC-1140.

5.Reset insulation and reattach Right Side Panel.

This Type K Thermocouple measures the temperature of the Electrical Compartment. If the temperature within the Electrical Compartment is above 158ºF (70°C), the control will display an F6 Fault.

To replace a defective EC Thermocouple:

1.Ensure “Cool Down” process is completed (“Cool Down” message will disappear upon completion) and unplug the oven.

2.Remove Right Side Panel.

3.Disconnect defective thermocouple from the I/O Control Board and install new one (P/N 700-1199). See page 61 for schematic.

4.Reattach Right Side Panel.
