Re: fan in the freezer stop working ater a while
You may have a serious issue with the wiring harness inside the refrigerator. You will need to have the technician come back out and check the continuity of the wires leading from the control board to the fan checked out. If there is no continuity, it is not repairable.

Hi, here are the error codes and meanings for your Refrigerator
Error Code, All Error Codes will have an ER on the left side, followed by the error on the right: Er IF - Icemaker Fan Error - This can be caused by frostaccumulation on or around the icemaker fan. Unplug the unit for 3-4hours to allow this to melt off. If error code persists, call CustomerService. Er FF - Freezer Fan Error - This can be caused by frost accumulationon or around the freezer fan. Unplug the unit for 3-4 hours to allowthis to melt off. If error code persists, call Customer Service. For remaining error codes, try unplugging the unit for a couple ofminutes to reset the unit. If the error code persists, call CustomerService Er FS - Freezer Sensor Error Er rS - Refrigerator Sensor Error Er ds - Defrost Sensor Error Er dH - Defrost Heater Error Er CF - Cooling Motor Error Er CO - Communications Error
Error Code Er FF This code is not to be confused with the O FF or demo mode error message. The "Er FF" error code indicates a problem with the unit's freezer fan. The freezer fan controls the temperature in the freezer. The source of this error is most likely ice buildup. As with the Er IF error, allowing the unit to thaw should resolve the issue. Contact customer service if the error code continues to be displayed after having thawed the unit.
Er FF is Error, Freezer Fan. The fan blade in the freezer is most likely blocked by some ice or frost. Clear that and the control will see the feedback from the fan showing that the motor is turning and the code will clear.
Er FF - Freezer Fan Error - This can be caused by frost accumulation on or around the freezer fan. Unplug the unit for 3-4 hours to allow this to melt off. If error code persists, call Customer Service.
er ff indicates that the computer on your refrig is not sensing freezer fan operation. a guess as to your problem is that the fan is hitting on ice (the noise your hearing) and teh fan is not able to reach operation speed causing the error code. the fix would be to remove the ice from the fan area either maually or by unplugging the unit and letting it defrost for several hours. also to reset the computer you will neeed to unplug it for a few minutes then plugging it back up. hope that helps thanks Peyton
I'm no major appliance repairman. However, after reading several posts, I investigated the issue further since I received an ER FF on the front panel. I have a LFX25960SW refrigerator. I pulled the top and bottom baskets out, and was able to take the back panel out from inside. There was a solid block of ice built up around both fans and wires. I took a blow dryer and gradually melted the ice around the fans and wires. Then, as I was able, I pulled the remaining ice chunks off of the wires. I put the thing back together and it cleared the message. My wife says no more LG appliances for us. :)
The error indicates the freezer fan is not functioning properly. The
fan supplies cold air to the refrigerator that is why it seems warmer.
The fan may be frozen, try unplugging it for a few hours to let it
thaw. Also check to see if something may have gotten into the vent
holes in the freezer that could be blocking the fan from turning.
