AUTO-TEST
This helps with a quick check
of
the loads and sensor (thermistor), which otherwise are difficult to
activate. NOTE: - Before using the AUTO-TEST it
is
advisable to check the correct operation
of
the
refrigerator lamps, which is used for signalling possible malfunctions.

Auto-Test Sequence
1. Heaters - 6 second test
For the 'Auto-test' to check the heater circuit, the evaporator must be sensing a temperature
of
-10°C
or
colder.
The defrost, gutter and duct heater (iffitted) are connected in parallel. 'Auto-test' only checks for
a circuit, therefore provided only 1
of
the heaters are okay the 'Auto-test' will not detect a failure.
To be sure that all heaters are in order, they must be checked with a test meter individually.
2.
Sensor - 6 second test
Auto-test checks for open
or
short circuit.
3.
Fan - 6 second test
Manually check the air flow.
4. Heater, Fan - 216 second test
Check the fan operation visually - test the heater manually.
Where the Auto-test sequence highlights a failure, CHECK the wiring connections at the plugs
and sockets of the various components.
