Have replaced the heater defrost assembly. Still freezes up. Waiting for a new conductor as I didn't know the old one could be blown (open) Is this the problem? Don't know what else to do!

I am assuming the heater defrost assembly is working as all runs normally for a few days.

As detailed as possible--explain the original problem that you were having with the refrigerator. Any error message displayed? Refrigerator too warm but freezer somewhat okay? Icemaker stopped functioning? Heavy frost accumulation on *everything* inside the freezer,etc. Post the SERIAL NUMBER* (located in the fresh food compartment on the side wall) Also---check the MODEL NUMBER again. There are two add'l letters at the end of the number---some have additional numbers as well (such as: 01---02---03 etc)

Okay--got your pm. LG Refrigerator Model: LFC25760ST Serial: 608KREL01412 Symptom: Food compartment too warm / Freezer "okay" Also showing an error: "er/dh" A few things to consider... Try replacing the CONTROLLER ASSY (6615JB2005H) which is next to the *evaporator coils* in the freezer. This is most likely the cause of the *er/dh* error (since you've already replaced the DEFROST HEATING ELEMENT). If this fails to resolve it---the MAIN BOARD may be at fault. If you haven't had the *ENERGY UPGRADE" performed yet---this would be a good time to have it done. This involves replacing the MAIN BOARD and the addition of small foam insulation strips at the top of both doors. Free of charge. Having this "upgrade" also eliminates another known problem in your model refrigerator (by serial number info)---and that would be---potential lightbulb relay failure on the MAIN BOARD. Your model was built in August 2006. To qualify for this free upgrade, visit: http://www.lgrefrigeratoroffer.com Last edited on Tue Sep 28th, 2010 02:52 am by john63 |

A Thousand Apologies... Your model is *not* one of the affected models for ENERGY UPDATES. These apply only to "French Door" models *with an in-the-door icemaker / chilled water dispenser assy* on the left-hand door. Sorry for the confusion...

Very good. Thank you for the info. Have already ordered the controller assembly, should have it tomorrow. Problem with the free upgrades is I bought this fridge used so I don't think I am eligible for them. Will check it out though.

If you still have the original defrost heating element---test it with a Volt / Ohm meter. A simple continuity test (battery current sent from one terminal to the other) will confirm if it's "good" or has "failed". Keep it as a spare---if the test shows that it is not defective.

you'd need a meter and know how ro use it If you have a Harbor Freight Store near you, they have these meters, w/battery but sometimes on sale for $ 1.99 if on sale, print sale page and take to store click on picture  click on picture  You could also probably use a few of these: click on picture

did you test the Defrost Heater and Sensor/Fuse before replacing... If not, that's a sure way to waste money May be a bad Controller .. If you have a Harbor Freight Store near you, they have these meters w/battery sometimes on sale for $ 1.99 if on sale, print sale page and take to store click on picture click on picture LFC25760ST Service Manual link PM'd

Ok fellow guru's. I'm really not a guru just a truck driver trying to fix a fridge! I STILL have an error message on the display. Er dH. I have replaced the heaater defrost assembly ( lots of blood to clean up from my sliced up fingers from the sharp fins above the heater itself!) Also replaced the conductor. Fridge seems to be working properly as there is no frost buildup on the back of the freezer compartment. Have a digital thermometer in the fridge ( cause the display only has the error message. Pretty constant temp between 38 degrees and 44 degrees. Freezer is @ 0 degrees. Is this the temperature control senser? HELP PLEASE!
