Thread: LG refrigerator = "Er FF"

how much do you think would be the approx cost for this ?
In my case, each we get the mesg, we turn off the refrig & start it back and
it works fine for half a day or so.
I removed all the ice but that does not seem to have solved the problem.
I don't have the water filter inside anymore. Removed it recently and since
then I have seen this problem emergr. Probably they are unrelated?

I don't remember exactly what we charged

If you pay an appliance repair company, expect the bill to be around $275-$400

Im not sure if this is related but this morning when I got up I could hear a humming noise. Sounds like a fan starting to fail or motor thats slightly off balance. When I open the fridge door the motor sound stops.

I actually lucked out. I thought I had purchased 3 yr warranty but found
that I had bought 5yr service plan from best buy for 149.99.
So the best buy guy changed the fan and reset the computer under
service plan.
I found the fan on e-bay being sold for 20 or 30 and the tech said it would have been abt 100 or more for him to come and fix the issue.
So this service call itself paid that 149.99 investment that I made 3.5 yrs ago.
Best.

It turns out the grinding noise I was hearing each night was ice building up on the evaporator fan located in the back of the freezer. When we pulled the panel off there was ice packed all around the fan. The repair man said he was going to have to replace the fan. After we deiced the fan with a hair dryer he pulled it our and handed it to me. The fan said it was a nominal 13v so I hooked it up to a 12V regulated power supply in the garage and it worked just fine. When testing the leads to the fan it only showed 1.5V with the door button pressed. When testing the mother board it shows only 3V output from the fan output leads. Once he said it was going to cost me another $125 in labor and $119 for the board I found the thread that said to unplug it for 1 min to reset the caps. After doin that it purs like a kitten and spits arctic cold air.

Total cost $75 diagnostic fee for repair

Definitely EFM and motherboard... not a fun job....

Somewhat common problem with LG I can now see....

First timer here and I just wanted to say THANKS! guys! I have recently learned that I own a garbage can LG calls a fridge and without the help of you guys and this site I would have been stuck. I recently recieved the infamous ER FF code and my warranty was out by like 4 months. First tried to de-ice but it kept coming back so I ordered and swapped out the main board and Freezer fan and now it's back to good again. Thanks again!

Freezer still worked. Fridge did not. Thanks to infor from this site - I pulled out unit, unplugged, took off lower back panel, then came round to front and removed all freezer drawers and trays. Put a ocsilating heat tower (set on low) and a fan on the kitchen floor which is exposed when the freezer door is open. Lots of continuous flow of water caome down the drip tube system in the back. It drips into the drip tray for evaporation but I had to carefully sop it up with little rags. My theory, leave the unit unplugged, doors open, fans blowing into the freezer area to thaw for at least 24 hours. The water was flowing for that long of a time on mine. Behind the back wall of the freezer It must have been completely frosted and iced up. I'm hoping that by letting it thaw so completely and dry somewhat due the the continuous use of fans that this will not recurr for several years. I put reinstalled everything, plugged it in, and so far the electronics and cooling systems are working good. Prior to this mine had been running well for 4 years. My only complaints to this point had related to ice machine jams and poorly designed, cheaply made refridgerator drawers.

upper right area contained a brick of ice nearly 3" thick (built up after 7 years). 2nd picture is back view of freezer rear panel. Center fan motor is freezer fan. Freezer fan was iced up and didn't spin. I warmed and dried all and everything works fine now. No tools required (except hair dryer & ceramic heater). No work done on rear side of unit. No reason to pull away from wall.
