That is a freezer fan motor error, the freezer fan is no longer running. Check the freezer fan for a loose connection, if everything checks out ok there you probably need to replace freezer fan.

ZFSB26DRESS water runs warm and freezer not staying cold.


It sounds like the condenser coils , the coils by the compressor , need cleaned badly . This (and the compressor cooling fan) , can cause the compressor to cut off on overload (due to the heat) , thereby not circulation refrigerant thru out the freezer coils .
The water line goes from inside the freezer door ( cold ) , under the refrig ( warm ) , then to the inside refrig water reservoir ( cold ) . After that , you should get cold water , until the reservoir is drained of cold water .

HELP!!__CALLING ANY GE FACTORY TECHS


You say " all thermistors check fine " , how did you check them ? Did you check for the 5-8 DC volts at the main control board , for the thermistors ? Did you do the diagnostic check for the thermistors from the control panel ? I'm sure you know there are 5 thermistors , since the refrig has the dual evap . Possibly the # 5 is bad , since it is the freezer temp " controller " , yet if it tells the board it's not cold enough , it still sends refrigerant to the refrig evap . Since the refrig evap has 2 fan motors , can't remember if there is a damper there also . Maybe when the # 3 thermistor is satisfied , it only cuts the fans off , even though refrigerant is still going thru the refrig evap .

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!!

I have code error "err ff"


I also had an "eR FF" message. I discovered that the fan inside the freezer compartment was locked up from accumulated frost. I unplugged the refreigerator for about 6 hours and left the freezer compartment door open so it could completely defrost. So far, it's been running smoothly (and more quietly!) for about 24 hours now. (My fingers are still crossed).
