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