INTERNAL AIR FLOW

The freezer fan draws air through the evaporator and into a duct in the rear wall of the freezer compartment.
This air exits through the fan grill at the top of the freezer compartment. The air behind the freezer coil cover
is also diverted through the divider partition to another fan, which supplies the cold air into the PC
compartment. The amount of air is controlled electronically by two sensors, which in turn regulate the speed
of both PC and FC fans to maintain selected temperatures in each compartment.
Air from the PC returns to the FC evaporator by way of the return air duct, which is built into the divider
partition. This air is drawn across the evaporator by the evaporator FC fan motor to be recirculated again
throughout the PC / FC compartments.

DIAGNOSTICS

A spanner symbol and LCD fault code will appear automatically if there is a fault in the temperature measuring
system, defrost system, fans or low ambient heater. (Refer diagram below)
When the PC door is opened, an alarm will sound. The number of beeps also indicates the fault code.
Pressing any of the control buttons can deactivate these alarms.
Example: When a fault develops, the LCD fault code appears with the spanner.
After rectifying the problem, the fault code and spanner will disappear. Faults are only rectified when that
feature is used. So in the case of a defrost fault, the code will remain until a defrost is initiated and it is
successful.

The previous 2 defrosts were aborted after 40 minutes.
Check defrost element assembly in the FC. If faulty, replace.
The resistance of all the temperature sensors are outside the normal range. (> 45K

Check the 6-way RAST connector at the power module.
Re-terminate the 6-way RAST connector.
Replace the power module.
