12.12 Cross / Base Rail Door Switches

1. Disconnect the refrigerator from the power supply.
2. Remove the door switch cover (located in the centre of the cross and base rails).
3. Unclip the encapsulated reed switch from the housing.
4. Replacement of the switch is done by cutting the old switch from the wiring and soldering in a new
switch, making sure both connecting wires are not shorting but are insulated with heat shrink sleeving.
Take care not to leave too much excess wire, as the reed switch must be able to be fitted back in to the
housing.
5. Refit in reverse order.
12.13 Removal Of Display Module – Non-Ice & Water Models
1. Disconnect the refrigerator from the power supply.
2. Remove all PC shelving.
3. Remove the bottom PC air duct cover.
4. Remove the polystyrene duct cover insulation.
5. Disconnect the low ambient heater – "T" model only.
6. Remove 1 screw from the top duct cover and unclip – "T" model only.
7. Compress the clips on the display module and release it from the duct cover.
8. Remove the PC sensor from its location.
9. Unplug the 5 and 3 way edge connectors from the display module.

12.14 PC Sensor Replacement

1. Disconnect the refrigerator from the power supply.
2. Remove all PC shelving.
3. Remove the bottom PC air duct cover.
4. Remove the polystyrene duct cover insulation.
5. Disconnect the low ambient heater - "T" model only.
6. Remove 1 screw from the top duct cover and unclip - "T" model only.
7. Remove the PC sensor from its location.
8. Replacement of the new sensor is done by cutting the wiring back from the sensor end and soldering in
a new sensor, making sure both connecting wires are not shorting, but are insulated with heat shrink
sleeving.
9. Refit in reverse order.

12.15 FC Sensor Replacement- "T" and "B" Models

1. Disconnect the refrigerator from the power supply.
2. Prise out the fan shroud using a flat blade screwdriver at the bottom of the grill cover.
3. Unclip the FC fan motor.
4. Remove the FC fan motor plug connection.
5. Unclip the FC sensor and remove the evaporator coil cover.
6. Replacement of the new sensor is done by cutting the wiring back from the sensor end and soldering in
a new sensor, making sure both connecting wires are not shorting, but are insulated with heat shrink
sleeving.
7. Refit in reverse order.

12.16 FC Sensor Replacement - 900 Models

1. Disconnect the refrigerator from the power supply.
2. Remove all bins/trays from the freezer and remove the FC drawer.
3. Remove the FC cover by removing two screws. Removal of the icemaker will make removal of the FC
cover easier. (Refer Removing Icemaker, Section 11.1.2.)
5. Remove the fan grille cover. This unclips with the aid of a small screwdriver.
6. Move the FC cover to access the FC sensor. (Removal of the FC cover is not necessary.)
7. Cut the FC sensor as close as possible to the sensor.
8. Replacement of the new sensor is done by cutting the wire off the new sensor about 60mm (2¼ inches)
from the sensor, stripping the wire back about 10mm (

12.17 Icemaker Temperature Sensor Replacement

1. Remove the icemaker (refer to Section 11.1.2).
2. The sensor wires are to be cut as close to the sensor as possible. Strip the wires back 10mm (
on the new sensor and on the wiring in the cabinet to allow the wires to be soldered together.
3. Place heat shrink onto both wires of the sensor.
