LG ER FF Code

9 posts in this topic

Forum readers,

Brand New to the site forgive me if I miss any forum etiquette. I did read a few post related to my problem and they helped. As a matter of fact it help me replace the freezer fan motor in my LG LRSC 26925TT side by side. Unfortunately it did not solve the problem. I did NO software updates or mother board replacement just the freezer fan motor. It still gives me the er ff code after a plug in. There is  also no ice build up and the unit has been down for a week. Are there any simple test or is it evident the tandem parts need replacing as well.

 

:thanks:  for any help

The Dean explains the pitfalls with this repair in detail here.  

 

Basically make sure you installed the upgraded evap fan:  http://www.repairclinic.com/PartDetail/Evaporator-Fan-Motor/4681JB1029A/1330410

 

Note the part number in the linked fan and compare with the one you replaced.

 

Not sure if the muthaboard in this model has been upgraded or not:  http://www.repairclinic.com/PartDetail/Main-Control-Board/EBR58010501/1472874

 

We'll sit tight and wait for the Dean to guide us.

No service bulletin concerning Main PCB although I suspect that's the booger.  Evap fan motor has been upgraded.

Depends on the Serial Number...

 

LG has been struggling with moisture contamination/damage in their refrigerators for some years now.

 

As of this posting---it *appears* that they're finally getting a handle on it.

 

For the LRSC26925 models---if the Serial Number is:

 

 

603MRXXX through 812MRXXX (Mar 2006 - December 2008)...

 

The MAIN BOARD was changed from (6871JB1929Y) to the revised/corrected part number (EBR58010501).

This corrected *overcooling* complaints.

LG servicers were also instructed to visually inspect the THERMISTORs in both---the Freezer and Refrigerator compartments---for "partially-buried" Thermistors (inside the blow-injected foam insulation).

Any Thermistor found "stuck" in the cured insulation---is to be pulled out and re-attached to the Thermistor Case/Cover (for accurate temperature sensing).

 

If the Serial Number is:

 

906MRxxx or older...

 

Both Door Gaskets were re-designed---to improve sealing (moisture control).

 

Freezer Door Gasket (4987JJ1010L)

 

Refrigerator Door Gasket (4987JJ1010M)

 

In your particular case---the Evaporator Fan Motor likely failed due to moisture contamination---shorting out the tiny intergrated-circuit inside the Fan Motor Housing.

Which then---damaged the Main Board.

 

Replace both.

 

Evaporator/Freezer Fan Motor (4681JB1029A)

 

Main Board (EBR58010501)

 

Other possibles---though less likely...

 

Damaged wiring in freezer door hinge (top of door)

 

Failing/failed Door Switch

Thanks  very much for all  the help. Works very much like my motorcycle boards every one willing to lend a hand, much appreciated.

I checked the serial number and my unit is an 2005 (502KRLR00152) bought in Jan 2006. I will try the main board if the cost does not out weigh the remaining life of the unit. I have replaced the freezer fan motor behind the ice maker.

I am assuming the thermistors can be checked with a meter? Where can I find a schematic on here to locate these parts on this unit?

 

I have been getting my LG parts from S**rs. For me the consumer they have been excellent in shipping and customer service and pricing have been excellent.

<<<I am assuming the thermistors can be checked with a meter?>>>

 

**********

 

No need to test the THERMISTORS---just pluck 'em out from the insulation---and attach them to the small white plastic "cage" (which can be seen in both compartments).

Sears does not "lend a hand" like that motorcycle forum does---and their return policy is woefully lacking compared to RepairClinic:)

Especially when it comes to electronics.

Much more knowledge in a short time . I will try the main control board next. It looks very easy to replace and somewhat cheaper than a new unit. I will also clean the coils and evaporator fan area which I may have been one of the millions to neglect this area for maintenance.
