Ice Maker (Finger Evaporator Fresh Food Compartment)
After pushing 'power on-off' to start automatic test or
turn on the load, the ice maker control will display the
test result on the freezer two digit display. When waiting
for the test to be automatically performed and the result
displayed, the test number (test ID) will flash on/off. After
the automatic test is completed the test result will be
displayed as "P" – pass, or "F" – Fail.
For an interactive test, the technician manually activates
the load using 'power on-off' and physically verifies the
system response. Pressing 'power on-off' again turns
the load off. The freezer display shows the current or
expected state of the load. During the load transition the
fresh food display flashes the test ID. After the last test
step in the ice maker test sequence is completed, the next
advancing action will scroll back around to the first ice
maker test. Stepping back from the first test, will scroll the
test sequence backwards to the last test in the sequence.
