SERVICE PROCEDURES
Note:
No work is to be carried out on the product while in a live situation. All
components can be at a 230volt potential. The product is to be turned off and
disconnected from the power source.
Electrical Safety Checks
Whenever any part of the electrical circuit is serviced or disturbed in the course of
carrying out service adjustments or repair, it is essential that insulation and earth
continuity tests are carried out using the appropriate test equipment.
4.1
Control Module
•
Remove the drain pan/tray.
•
Remove the two screws securing the module to the cabinet.
•
Pull the module outwards.
•
Remove all the connectors from the control module.
•
Refit the module in reverse order making sure all wiring is secured in the module
and the wiring harness is located in the module slot.
4.2
Compressor Overload
Remove the compressor cover. Once the cover is removed, the compressor
connector from the control module needs to be removed before the overload is
removed by pulling off the compressor terminals. An Ohmmeter is used to test for
continuity of the overload.
4.3
FC & PC Sensors
The FC & PC sensor are tested at the module. The module is to be removed and the
Sensor RAST connector can be removed for testing.
4.3.1 To Replace PC Sensor
•
Unplug the refrigerator from the power source.
•
Remove control housing and rear duct from housing.
•
Disconnect all connectors to give access to PC sensor.
•
Replacement of the sensor is done by cutting the wiring to the old sensor as close
to the sensor as possible. Strip each wire back far enough (about 10mm) to allow
it to be soldered to the wiring of the new sensor. Strip each wire of the new
sensor back a similar amount and slide some heat shrink sleaving over each wire.
Solder a wire from the new sensor to a wire of the harness that was going to the
old sensor. Slide the heat shrink sleaving over the joint and heat to shrink.
Repeat with the other wires.
•
Reassemble in reverse order.
•
Test light operation after assembly.
4.3.2 To Replace FC Sensor
•
Unplug the refrigerator from the power source.
•
Remove air duct (on B models). Note: Care should be taken in removing duct so
as not to damage duct or cabinet.
•
Remove rear evaporator cover, disconnect fan wiring and remove cover from
refrigerator.
