LG Refrigerator LRBC22544st

Hi - I have a 2 year old LG, LRBC22544st and it was showing ER FF. I opened up the back panel of the freezer and there were big chunks of ice impeding the fan. I removed the ice and it now runs fine. But, I don't want the problem to occur again so I believe I should replace the defrost sensor (ADC). I want to order the piece and replace it but I don't know where it is located on the fridge. Does anyone know where I can locate the ADC on my fridge? Thanks.

Take off the back panel and cut the insullation as in the photo and this will never happen again. What happens is the water gets trapped and then ice forms and builds up and causes the blockage.

What does message: Er FF mean?

That means the freezer fan is blocked, you need to order a new High voltage board, the ice has built up enough from not defrosting that it is interfering with the operation of the evaporator fan.

LG refrigerator lrsc26944tt error code ER FF

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. :)

Error message Er FF

er ff means that the control board is not sensing evap fan motor operation this means either a bad fan motor ice in the fan motor or bad control board. you can verify fan operation by opening freezer door and feeling for old air blowing from back of freezer compartment. you will have to push in the light switch to get fan operation.
for corndo that has same problem you actually have a different problem. er dh means the control board is not sensing defrost heater operation. the most common culprit is a bad defrost sensor. message me back if you need instructions for trouble shooting..thx peyton

Error code er ff on my kenmore elite bottomfreezer model 795.7756

I fixed it. ER FF is "Error Freezer Fan." Once the evaporator fan stops turning for more than 115 seconds, this error message will be displayed. This fridge is poorly designed and is not designed with air gaps or enough air gaps to allow air behind the back panel of the freezer where the fans and condenser coils are located thus causing ice to build up around the fan and it's ability to spin. The evaporator fan helps cirulate the cold air generated by the condenser coils.

The fix is (1) defrost your refrigerator which means you'll loose all your food if you don't have another unit to keep the food in until it's done defrosting or (2) to dismantle the entire freezer by removing all the trays and railing so that you can pull the back panel far enough to get the front end of a hair dryer over the top lip of the panel to melt the ice. My unit had ice build at the top right and left corners behind the panel. I opted for the latter and didn't have to throw any food away.

This is going to be an annual chore if I want to keep this refrigerator. We should all ban together and call for a recall.
