scroll the test sequence backwards to the last test in the

Test 48C: Freezer Recovery Mode (FRM)
(See Flow Chart Test #48C)
If the FRM Exceed Flag is True, then Freezer Temp
window of the UI will display "Fr". If the FRM Exceed
Flag is False, then Freezer Temp window of the UI will
display "1". While in 48C, the ON/OFF icon will be
illuminated. If pressed and held for 5 seconds, the value
display in the Freezer display will flash 3 times and then
the display will be updated to show "1" and the FRM
Timer will be reset to 0 and the FRM Exceeded Flag shall
set to False.
Test 49C: EEV Manual On/Off
(See Flow Chart Test #49C)
To start this interactive test, touch the ON/OFF key to
fully open the valve. Fresh Food display starts flashing
the test ID until EEV is fully open and Fresh Food
displays "on". Pushing the ON/OFF key again will close
the valve. Fresh Food display will flash the test ID
while the EEV is driven back to the closed position and
Freezer display shows "OFF". If ON/OFF key is pressed
during transitional state of EEV, the input is ignored.
Prior to sealed system evacuation, the service
technician needs to open the Ice maker EEV and
then power down the system. (Unplug refrigerator's
AC power cable). The valve will close automati-
cally on system (POR) when the IM is turned "On"
and the system AC power is restored. The POR
sequence is followed and, if needed, the reentry
back into the diagnostic mode can be performed.
