So glad to have found your post. Have had problems with 25960TT LG for a couple years. Anyway problem now is Error FF. I removed back panel and waited till ice melted, and started fridge again. It worked for about 1 month, then Error FF again. I saw where you said to trim the insulation. Is it the top part of the onsulation or the bottom part. I trim it on an angle across(45 degrees).
Where from in Canada-lived various locations for 31 years. Wife originally from London, Ont.
It isn't the insulation or the tubing. It is a design flaw in the icemaker heater. Your heater is kaput and the heater fan probably is as well. LGE does not have a fix. They can only replace the heater and fan, and then wait for it to blow out again.

The FF error means that the freezer fan isn't working properly. The motor may have malfunctioned or ice has built up and is preventing the fan from turning. Unplug the refrigerator, remove the food to other cold storage locations (cooler, another fridge) and allow it to defrost. Dry up any moisture around the unit. Plug it back in and allow it to cool for 4 hours. If the error returns, the refrigeratr needs service.
Generally, you need to replace the fan motor and the motherboard in the refrigerator. (The motor keeps trying to spin until it becomes damaged, even if the problem was ice build up.) The fan pushes the air into the refrigerator to keep it cool. The freezer is more directly cooled by the refrigerant cycling through the unit. If your refrigerator is still under warranty, contact LG. (There is a 1 year warranty on most of the unit. The sealed refrigerant system has a 7 year warranty on those parts.)
I hope this helps.
(Unfortunately, I do not have a source for parts.)
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.
I found another post that suggested the following. Did it and found wires/connections frozen with a huge piece of ice.
Make sure unit is unpluged!
Removed baskets (2), unscrewed back panel of freezer. A little tricky to get out. There will be electrical connections attached to the panel but you can disconnect/reconnect these. Mine were on the top, left corner. I used a blow dryer to melt the ice chunck. Dried up all the water, replaced back, baskets.
I then took the panel off the very back of the unit as the melted ice had drained into the drip pan. I cleaned the drain pan of water, dust. They don't make this an easy task for the homeowner. Replaced the back, plugged it back in and all is working again. Don't know for how long until this happens again. But....no more LG products for this homeowner.
We remodeled the kitchen 2 years ago and went stainless steel. My 16 year old Kitchenaide is still running in the garage. Guess I'll go back to that model when the LG bits the dust.
The ER-FF problem that you have is: ERROR -FAN FREEZER so it means that you have a problem with maybe the fan motor or if it's a bottom mount freezer maybe ice built up on the fan motor so it's blockin the fan motor.
Hope i helped u a little bit ! :)
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.
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.
