Replacement Of Compressor

• Disconnect the refrigerator from the power supply.
• Remove the drawer from the cabinetry.
• Check the compressor resistances at the wiring harness to the power/control module.
• The whole drawer can be rotated to place it upside down to make it easier to work on.
Note: Care is required to prevent damage to the floor and to the drawer. Do not allow any pressure to
be applied to the User interface, as it is glass. If in doubt, remove the interface before inverting the
drawer.
• Remove the 5 self-tapping screws securing the rear panel cover to the back of the cabinet and remove
the panel.
• Remove the screw attaching the 3 earth wires to the earth tab.
• Remove the 16 self-tapping screws attaching the base panel to the base of the cabinet and remove the
base panel.
Note: A screwdriver bit with a length of at least 160mm is required to reach 3 screws on the edge of the
panel on one side.
This exposes the compressor mounting. The refrigerant can be reclaimed at this stage. The wiring to the
compressor can be disconnected and all pipes to the compressor can then be un-brazed.
Note: The body of the compressor base mount is plastic and care needs to be taken to prevent damage in
this area.
Having un-sweated the pipe work, the 2 screws securing the compressor base mount to the body of the
cabinet can be removed. This enables the compressor to be lifted clear of the cabinet.
Refitting of the replacement compressor is done upside down once the compressor has been mounted on its
base mount.
Refit the overload and plug to the compressor pins.
Refitting the compressor base mount to the base of the cabinet is done by holding the screw fastening side
slightly higher than the other side and pushing the edge in to locate it with a screw driver.
Refit the replacement filter drier, pressure test, evacuate and recharge.
In refitting the base panel, ensure that the pipe work is not going to generate rattles.

Compartment Spills And Clean Up Procedure

A service technician can remove the lower front access panel (refer to Section 12.3.5), and then place a
shallow container under the air intake on the left hand side of the base panel to catch the contents from the
water evaporation tray. Next place a wide strip of PVC tape across the front edge of the water evaporation
tray and base panel (this will prevent water running between the tray and the base panel). Having removed
the evaporator cover (refer to Section 12.3.17) to gain access to the evaporator area, with a sponge and a
small brush with a 500mm long handle, scrub the evaporator area and the water evaporation tray the
spillage has run into. Then proceed to flush out the tray with water, using a sponge to soak up the surplus
liquid from within the water evaporation tray.
