WARNING! 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 prevents the
appliance from starting and the LCD from lighting up if it blows. 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 panel holding the electrical components, using the
procedure 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.
- Perform the above operations in reverse order to reassemble.
- Close the panel holding the electrical components, using the
procedure described in point 5.3.3
5.3.5 BELT MOTOR BRUSH REPLACEMENT
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 in point 5.3.3.
5.3.6 REPLACING THE BELT MOTOR
After the replacing some sets of brushes, it may be necessary to fit a
new belt motor (Tab.A and B part.42).
After carrying out the operations described in 5.1 above, proceed 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.
- Install the gear motor again , taking care to align it to the belt shaft
correctly
- Close the panel holding the components as described in 5.3.3
5.4 REPLACING 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:
T75E-T97E: Remove the left adjustable side wall (fig.10 item I) by
unfastening the knobs (fig.10 item L).
- Remove the top left hatch (fig.18 item A) by unfastening the fixing
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.
- Open the electrical panel following the procedure described in point
5.3.1.
- Remove the rearm button cover and unscrew the thermostat fixing
nut (fig.14 item P).
- Disconnect the thermostat faston connectors.
- Replace the thermostat with the relative sensor and restore any
damaged areas of the insulation.
- Carry out the above operations in reverse order to reassemble.
- Close the electrical panel following the procedure described in
point 5.3.3.
TT98E: the oven has two independent, manually reset safety
thermostats, one for the left side (fig.14 part.P) and one on the right
side of the oven (fig.36 part.G).
Open the front door (fig.10 part.S) and slide the conveyor belt from
the baking chamber, following the steps in point 5.2.1.
- Slide out the bottom blower from the side concerned so as to check
the position of the actual thermostat sensor through the baking
chamber.
- Remove the bottom hatch (fig.36 part.A or H) loosening the
fastening screws.
- Slide out the safety thermostat sensor.
- Open the electrical panel from the side concerned, following the
steps in point 5.3.1.
