correctly
- Close the panel holding the components as described in 5.3.4
5.4 CHANGING THE SAFETY THERMOSTAT
WARNING! Regularly check that the safety thermostat is
operating correctly.
After carrying out the operations described in 5.1 above, to replace
the safety thermostat proceed as follows:

39 item L).
- To take apart the regulation of the air (picture 17 part. A) (only for
the T97G)
- Remove the top left door (fig. 39 item A) by unfastening the fixing
screws.
- Move the insulating material to one side and extract the thermostat
sensor (fig. 39 item V).
- Open the panel holding the electrical components, using the
procedure described in point 5.3.1.
- Remove the reset button cover plug and unfasten the thermostat
fixing nut (fig. 29 item P).
- Disconnect the thermostat faston connectors.
- Replace the thermostat with the relative sensor and restore any
portion of insulating material that may have been damaged.
PANEL HOLDING THE
- Perform the above operations in reverse order to reassemble.
- Close the panel holding the electrical components, using the
procedure described in point 5.3.4
5.5 CHANGING THE THERMOCOUPLE
After carrying out the operations described in 5.1 above, to change
the thermocouple proceed as follows:

screws.
- Unfasten the thermocouple fixing nut (fig. 39 item E).
- Mark and disconnect the two cables feeding the thermocouple.
- Change the thermocouple, making sure you lock it in the position
indicated in fig. 39 with the ceramic part to the correct distance from
the wall of the cooking chamber
- Perform the above operations in reverse order to reassemble,
making sure that the connectors are in the right positions.
NOTE! If a temperature of 699 is displayed, this indicates that
the thermocouple is disconnected.
5.6 CHANGING THE LCD MONITOR OR CONTROL
PANEL
