My LG refrigerator has the code E rF. Do I have to replace the fan motor? Or what? The ice and water is not working.
Grace Nunes,
LG fridge has error err and ff = That error code is your freezer (evaporator) fan motor that’s inside your freezer.
It will need to be replaced.

My LG fridge has err and ff on my display. I am also hear a vibration when I close the doors. When I open the doors the noise stops.
Leann,
LG refrigerator Error Code Er 1F
The IF error code indicates that the refrigerator has detected a problem with the refrigerator’s ice maker fan.
This can sometimes occur when frost or ice buildup occurs around the ice maker fan.
Note: For french door refrigerators, please check the gasket along side the door.
Frost buildup can occur if the doors on the unit are not aligned properly.
For more information on door alignment and proper refrigerator leveling, refer to LG Refrigerator Leveling Instructions.

How do I know which is what is wrong? This makes me ill. I bought this very expensive refrigerator (french doors, oversize, stainless steel) to replace one I thought was going out three years ago. I kept the old one as a backup in our laundry room. The one in laundry room is still going, this one keeps getting this error code. I tried turning it off overnight, it worked fine for about two hours after I turned the switch back on, but it’s back. Any help is appreciated, I am not a repair person at all but willing to learn!
Lizell Strauss,
An dH error code on the LG refrigerator’s display means that the unit spent more than 1 hour trying to defrost. During defrost, the refrigerator will increase the temperature at the evaporator to a preset temperature depending on the model. If this temperature is not reached within 1 hour, the DH error code will display. You may have a defrost issue with the fridge. Have you given the fridge time to clear the error on its own? You may need to give it some time and it will go away since it is happening during defrost mode. Try unplugging the fridge for 10 minutes and see if that clears the errors.

We have a double door LG fridge and freezer – Serial No 406TRCNOK843. The computer shows at Freezer dH and at the Fridge E. What should we do? We bought the refrigerator a year ago.
