Component Removal & Replacement

11.4.1

Removal Of Power/Control Module

Location: Behind a metal plate in the unit compartment on the left hand side when viewed from the
rear of the refrigerator.
1.  Unplug the refrigerator from the outlet socket.
2.  Remove the cover mounting screws securing the metal plate and remove the plate.
3.  Unclip the plastic locking tab on the underside of the module cover and remove the module. It

may be necessary to move the power cable and earth wire 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 rear edges of the power/control module.
6.  Remove the connectors (except the transformer) along the bottom edge.
7.  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.

11.4.2

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 and trays.
3.  Unclip the PC air duct cover.
4.  Remove the polystyrene duct cover insulation.
5.  Turn the air duct cover to expose the back.
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

(2”) from the sensor, stripping the wire back about 10mm (0.4”), stripping the old sensor wiring
back about 10mm (0.4”), and after sliding heat shrink onto the wires, connecting 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 the sensor is protruding at least 12mm / ½”).

11.4.3

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 and trays.
3.  Unclip the PC air duct cover.
4.  Remove the polystyrene duct cover insulation.
5.  Turn the air duct cover to expose the back.
6.  Remove the PC sensor from the cover, then remove the air duct 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

(2.4”) from the sensor, stripping the wire back about 10mm, stripping the old sensor wiring
back about 10mm (0.4”), and after sliding heat shrink onto the wires, 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.
