Question about LG LRBC22544 Bottom Freezer Refrigerator

Open Question

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.

    The problem persist..
    I tested the Fan Freezer is ok.
    I tested the resistor is ok.
    The evaparator coil is completly clean.....
    When I connected to the AC, start running ok. up to more or less 3 min, then go to ERR FF, and keep this status permanently. Then I unplug from AC and plug again, start display ok, then after few minute go and go fo ERR FF, any command not respond........
    So, please foward me to another posible fixing......

    Regards,

If it was.. ICE.. NOT frost... Dont think it was a defrost problem, I read on hear somewhere about LGs having a problem with warm air leakage that maybe causing your problem.. i will see if i can find that post for you

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.

My LG display is reading ER FF what does this mean and what can I do to fix it?


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.

Hope helps.

Refrigerator LG LFC25760ST Serial # 701KRUC00022 PROBLEM ERROR CODE: ER FF What is this? How can I solve the problem?


Hi, The FF error code indicates that the freezer fan motor is defective. You could also get this code if ice is preventing the fan from turning. Please set up service for refrigerator before the fan motor gets worse !

It's written like this in the repair manual:
Which means what I just wrote above about the fan motor!!
Error detection category:
Abnormality of BLDC FAN Motor for Mechanic Room

Error Display: FF

Error generation factors:

It is caused when F/B signal isn’t over 115 seconds during BLDC FAN motor operating


Remarks:
Poor BLDC Motor connection, DRIVE IC, and TR.You can check the below trick, if that might work on your model :-

Pull the top and bottom baskets out, and take the back panel out from inside. There would be asolid block of ice built up around both fans and wires. Take a blow dryer and gradually melt the ice around the fans and wires. Then, pull the remaining ice chunks off of the wires. Then put the thing back together and it should clear the message.

Unless call a tech from LG.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

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. :)

Freezer cold/fridge warm


You have a defrost issue and needs to be serviced by a qualified LG technician.  The freezer fan motor is blocked by a large chunk of ice behind the rear panel of the freezer section.  You will need to remove the rear panel to get access to the fan and get rid of the ice.  This will get your refrigerator working again but this problem will return.  You will need to have your control board replaced.

Error Code ER FF


I had the same problem. I can tell you that simply unplugging the fridge and letting it defrost isn't going to work. You need to get take it apart.

I had the Er FF code about 2 months ago and let the freezer defrost for a couple hours and it started working again. Then two days ago I got the error again. This time I decided to get inside there.

First and foremost, UNPLUG the fridge and TURN OFF the water!

Next empty everything out of the freezer and start taking it apart. You have to get everything out of it to get that back panel off. This includes the ice maker and the rails that the drawers slide on.

Now that the freezer is completely empty there are two screws that hole the back panel on. In my freezer one is a white screw high in the center and one was a gold screw in the little panel that the ice maker hooked up to.

Next grab the back panel by the little fins on the top of it in the middle. Give it a good firm pull, but take care not to yank it too far... it's still connected by wires back there. When I pulled my panel out I found a HUGE chunk of ice on the top of the panel just to the right of the fan that feeds cold are to the fridge. Get that thing off of there taking care not to damage the foam insulation and watch those shiny metal fins that are behind the panel.

While you're putting it back together try to dry everything off as much as possible (I tried see the bright side of the whole evolution and realized I could really clean my freezer).

Once it's all put back together plug that baby in, turn on the water, and enjoy the next four hours as it gets back to being cold.

I'd say you need moderate tinkering skill to do this. If you only own one screwdriver and you never use it you should probably call someone.

Hope this helps!
