LG Model No GR-B207WTQ

SOURCE: Error code ER FF

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.

Had the same problem + a weird noise, which turned out to be ice build up on the blower fan. Unplugged overnight and then opened the lower back panel. There is a small fan that blows over some small coils at the bottom of the box. There is also a drip pan that should be "full" of water. I sponged out the drip pan, put the panel back on and then plugged back in. Works great.

Turn off the switch for the icemaker, then flip the circuit breaker to off for a few seconds and turn it back on. The display should remain lit and operable, but you won't have an icemaker. See service manual pg. 32: http://136.166.4.200/contents/Fridge/LFX25960/LFX25960_Service_Manual.pdf

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.
