ELECTRICAL PANEL
After carrying out the operations described in 5.1 above, to replace
components on the electrical panel proceed as follows:
- Open the electrical panel components as described in point 5.3.1
- Disconnect the component electrically.
- Replace the component.
- To refit, carry out the above steps in reverse order, taking care to
connect the component correctly.
- Close the electrical panel following the procedure described in
point 5.3.3.
NOTE: If the electronic card has to be replaced, perform a
general Reset of the appliance as described in point 5.17.
5.3.3 CLOSING THE ELECTRICAL PANEL
After carrying out the operations described in 5.1 above, to close the
electrical panel proceed as follows:
T75E-T97E: Remove the two nuts (fig.17 item K) and replace them
on the screw (fig.17 item J).
- Slide the electrical panel inwards (fig.17 item Z), allowing the
power cable to slide through the cable clamp (fig.11 item N).
- Fit the screws (fig.17 item V).
- Tighten the cable clamp (fig.11 item M).
TT98E: For the electrical panel on the opposite side of the gear
motor, close by turning the switch panel (fig.17 item Z) and fit the
screws (fig.17 item V).
For the electrical panel on the gear motor, turn the side panel and
tighten the 2 screws (fig.16 part L).
T64E: Close the side panel by turning and tighten the 2 side
fastening screws.
IMPORTANT! When sliding and repositioning the electrical
panel take great care not to scrape, block or crush the safety
thermostat wires or capillary.
5.3.4 CHANGING THE FUSE
The electrical circuit is fitted with a fuse which, in case it burns out,
prevents the appliance and control panel from starting. If this
happens, check the state of the fuse and replace it if necessary.
After carrying out the operations described in point 5.1 above,
proceed as follows:
- Open the electrical panel components as described in point 5.3.1
- Remove the fuse (fig. 17 item
N), check it, and if necessary replace it with another of the same
type.
COMPONENTS ON
- Carry out the steps in reverse order to reassemble.
- Close the electrical panel following the procedure described in
point 5.3.3.
5.3.5 BELT MOTOR BRUSH REPLACEMENT
(T75E-T97E-TT98E only)
NOTE: The belt motor (Tab.A and B part.42) has two brushes
inside (Tab.A and B part.35) which become worn with use, at
which point they need replacing.
Make sure that the brushes are not worn and if they are, replace
them. There is a spare set in the gear motor compartment. It is a
good idea always to keep a spare set of brushes handy.
Carry out the operations in point 5.1, proceeding as follows:
- Open the electric panel on the gear motor side, following the
procedure in point 5.3.1
- Unscrew the two caps covering the brushes and remove the brushes.
- Insert the new brushes and refit the two caps covering the brushes.
- Close the electrical panel following the procedure described in
point 5.3.3.
5.3.6 MOTOR/BELT GEAR MOTOR REPLACEMENT
T75E-T97E-TT98E only: after replacing some sets of brushes, it
may be necessary to fit a new belt motor (Tab.A and B item 42).
Carry out the operations in point 5.1, proceeding as follows:
Open the panel holding the electric components on the gear motor
side, as described in point 5.3.1
- Dismantle the gear motor, take it to a worktop, and replace the
motor (if any).
- Install the gear motor again, taking care to align it to the belt shaft
THE correctly
Close the panel holding the components as described in 5.3.3
5.4 REPLACING THE SAFETY THERMOSTAT
IMPORTANT!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:
T75E T97E: Remove the left adjustable side wall (fig.10 item I) by
unfastening the knobs (fig.10 item L).
- Remove the top left door (fig.18 item A) by unfastening the
fastening screws.
- Move the insulation and loosen the two screws (fig.19 item C)
locking the thermostat sensor.
- Remove the rear panel (fig.19 item D) by unfastening the fixing
screws and pull out the thermostat sensor located inside the
insulation.

nut (fig.14 item P).
- Disconnect the thermostat fastons.
- Replace the thermostat with the relative sensor and restore any
damaged areas of the insulation.
- Carry out the steps in reverse order to reassemble.
- Close the electrical panel following the procedure described in
point 5.3.3.
TT98E: The oven has two independent safety thermostats with
manual reset: one for the left side (fig.14 item P) and one on the right
side of the oven (fig.36 item G).
Open the front door (fig.10 item S) and slide the conveyor belt from
the baking chamber, following the steps in point 5.2.1.
