COMPONENT FUNCTIONS
General Information
The power module is made up of a number of smaller individual modules (sections), each one controlling a
functional component. The modules are linked together when required to control a particular function or fun-
ctions. The linking of the individual modules is optional and therefore allows for each module to be switched
ON or OFF, this is determined from the data stored or collected by the modules and the results of module
comparisons.
The power module memory stores information such as temperatures and times.
Having individual set of parameter values built in to it, directly aimed at providing the specifi c control needs
for the physical and system characteristics of the model type.
Fridge & Freezer Control
The power module monitors the fridge and freezer air sensors, comparing their sensor resistance values with
the cut-in and cut-out parameter values stored in its memory.
Although the parameters are set, they allow for adjustment within those parameters so that the user has
control. The results from the comparisons will determine if cooling is initiated, other circuits of the module will
also use the results.
The power module will enable normal operation provided there is no malfunction condition.
Fridge or Freezer Malfunction Module
The fridge or freezer malfunction module enables the appliance to continue operating in the unlikely hood of
the fridge or freezer sensors failing. Pre-set timed functions stored in the modules memory is used to cycle
cold request on and off.
A malfunction occurs when the fridge or freezer cabinet sensors return a value to the module of either
Open or Closed circuit, rather than a particular resistance value.
Evaporator Fan Module
The freezer fan is located above the evaporator coil and is designed to distribute the cold air produced by the
evaporator coil uniformly inside the freezer compartment and when necessary in the fridge compartment.
The freezer fan is managed by the module and is switched on/off after a preset time interval that is parame-
terised in the modules memory after a compressor start/stop.
The fan will not operate when in the defrost cycle.
After the defrost cycle the fan starts after a timed interval following a compressor start, this interval is also
parameterised in the modules memory; this interval is different from the interval programmed for normal
operating conditions.
Electronic Motorised Damper Assembly (Baffl e)
The purpose of the damper is to allow the cold air produced by the evaporator to be distributed inside the
refrigerator compartment.
The damper is located in the top left hand (SX) corner of the fridge compartment. It is controlled by a fridge
air sensor (thermistor) positioned in the centre of the rear wall of the fridge. Cold air from the evaporator is
distributed in the refrigerator compartment.
