12.4 COMPONENT REMOVAL & REPLACEMENT
12.4.1

Removal Of Power/Control Module

Located in the unit compartment on the right hand side and held in place by 2 self-tapping screws.
1. Unplug the refrigerator from the outlet socket.
2. Remove the cover mounting screw and remove the cover.
3. Remove the screw holding the module to the unit compartment. It may be necessary to move the
power cable and earth wire to the inverter over the inverter to remove the module.
4. Pull the power/control module outwards to disengage the mounting lugs at the back of the
module.
5. Remove all connectors along the top and side edges of the power/control module.
6. Remove the defrost connector (brown wires).
7. Remove the inverter connector.
8. Refit in reverse order.
Note: It is important that the power/control module is clipped securely to the side of the unit compartment and
the copper earth spring clip is not damaged, as this maintains good earthing and provides a low inductance
path to the chassis for RF voltage. Check that the flat pins at the back of the module are properly engaged
with the lugs on the unit compartment when refitting.
12.4.2

PC Sensor Replacement

Located in the provision compartment and attached to the PC duct cover.
1. Unplug the refrigerator from the outlet socket.
2. Remove all the PC shelving.
3. Unclip the PC air duct cover but do not remove.
4. Remove the polystyrene duct cover insulation.
5. Turn the PC cover to expose the back of the cover.
6. Remove the PC sensor from the cover and cut off the sensor wires as close to the sensor as possible.
7. Replacement of the new sensor is done by cutting the wire off the new sensor about 50mm from the
sensor, stripping the wire back about 10mm, stripping the old sensor wiring back about 10mm, and
soldering the new sensor to the old wiring, making sure both connecting wires are not shorting but are
insulated with heat shrink sleeving.
8. Refit in reverse order. (Ensure that sensor is protruding at least 12mm.)
12.4.3

PC2 Sensor Replacement

This sensor is located at the rear of the water tank. It is held in place by a piece of aluminium tape.
1. Unplug the refrigerator from the outlet socket.
2. Remove all the PC shelving.
3. Unclip the PC air duct cover but do not remove.
4. Remove the polystyrene duct cover insulation.
5. Turn the PC cover to expose the back of the cover.
6. Remove the PC sensor from the cover.
7. Remove the tank cover to expose the tank.
8. Remove the aluminium tape holding the sensor and cut sensor wires as close to the sensor as possible.
9. Replacement of the new sensor is done by cutting the wire off the new sensor about 60mm from the
sensor, stripping the wire back about 10mm, stripping the old sensor wiring back about 10mm, and
soldering the new sensor to the old wiring, making sure both connecting wires are not shorting but are
insulated with heat shrink sleeving.
10. Ensure the tank is dry, then re-tape the sensor onto the tank using a new piece of aluminium tape.
11. Refit in reverse order.
