Freezer is defrosting and it stopped making ice yesterday

You will need to run the unit through the diagnostic mode See page #21 in the manual lick for complete details. This will show stored error codes. Troubleshooting without error codes starts on page #37. Compressor troubleshooting is on page #61.

Press the Ice Plus button and Freezer button simultaneously to get into diagnostic mode.

All errors, except for “Er rt”, “Er SS”, “Er IS”, “Er gF”, “Er It”, “Er HS”,
“Er IS(except for Icing sensor)”, “Er gF”, “Er It” error, are displayed.
“Er IS” which is displayed without input of user is the error of Icing Sensor.
