Hope this helps; keep us updated.

it means there is a fault with the units compressor fan you will notice the fridge is running with less noise you will need to call a service man to come fix it good luck

ER in temp means error code next 2 letters are first letter of part giving problem or where problem located.. if " ER DH" means def heater not coming on, does not mean heater bad but def control bad not letting voltage to heater. could need main bd also

That stands for "error defrost heater"
Even though the refrigerator has gone through a defrost cycle, if a temp sensor does not reach a set temp within an hour, that error will display. You may have a bad defrost heater, defrost relay, thermal fuse, blocked defrost drain,..... something wrong with the defrost system anyway.

it the def t-stat, def. thermistor, or def. fuse whatever lg decides to call it this week that is causing your issue

Hi. Error FF is your Fresh Food Fan. Otherwords, the evaporator fan motor has failed. You should replace the motor and motherboard. You may get by just replacing the motor. Sears doesn't manufacture the refrigerator. They just pay extra to have Kenmore put on it. Its the manufacturer that needs to back their equipment. If you bought it from Lowes, you can't hold Lowes responsible for the ongoing issue. They sell the same refrigerator. Anytime this model refrigerator displays an Error code, unplug it for 5 miniutes and replug it. Sometimes it was a computer misfuction. Good luck! Mack
