Compressor Compartment Layout
The diagrams below will assist in identifying the various pipes within the compressor compartment. They
should be read in conjunction with the full system diagram (refer to Diagram 4.4).
Diagram 4.9
4.10 Cross Rail
The cross rail contains part of the condenser copper tubing (mullion heater) providing heat to the gasket
area between the PC and FC compartments, preventing sweating of the gasket. Also mounted on the cross
rail is the Reed Sensor, under the plastic cover in the centre.
4.11 Door and Door Hinge
On the Designer models, the upper door hinge is concealed and cannot be seen with the door closed. The
upper door height is extended past the top of the cabinet to cover the hinge area.
4.12 Compressor
The compressor is turned on when cooling is required. It is switched by a Triac (solid state switching device)
on the power/control module.
4.13 Thermal Fuse
There are two thermal fuses mounted in the wiring harness of the defrost element, having a tripping
temperature of 72
O
C. Once open circuit they cannot be reset. Replacement is part of the element heater
assembly.
These fuses in both leads of the element protect the refrigerator from any over heating through failure of the
element itself or a triac failure in the power/control module. Both sides are protected in case phase and
neutral are reversed.
NOTE:
Care should be taken if manually defrosting the evaporator if using heat guns, that the thermal fuses
are not over heated.
4.14 Drain Heater Wire
A drain heater wire is fitted to all cabinets except R134a B models. This drain heater helps to prevent the
drain tube from blocking with ice. The wire clips onto the double-pass defrost element, with the tail of the
heater wire in the drain tube, thus conducting heat from the defrost element into the drain tube area during
defrost.
