er dH error message on LG refrigerator
« on: September 18, 2015, 04:13:33 PM »

I have a LG model LAC26945TT that is about 8 years old.  I started getting the error message er dH message a few months ago.  I would unplug and plug the refrigerator and the message would go away for a day or 2, and then re appear.

I found here that some have replaced the thermostat, so I did that first.  Did not change a thing.  I then ordered a re manufactured control board (LG no longer makes this part) and that worked for  a couple of months, no problem.  Sadly the error message er dH occurred again.  I was able to replace the control board at no charge, since it was only 2 months old.  Again, second board and error message er dH is happening again.

So, what now?  Everything cools great, and I really like the refrigerator.  I hate to throw it out, but I'm still having problems with the error message for the defrosting of the refrigerator.  What would be the next part I should replace to hopefully fix the problem?

Thanks.

check the defrost sensor. 90% of the time that is the issue. Since you already have the board.

Usually I find the fuse open.

I agree it is normally that thermal fuse if it's warranty I replace all three on LG and usually techline and LG agree just replace them all.

Thanks for all your help.  Where is the thermal fuse located?  I have already replaced the thermostat and the control board. 

May replace the sheath heater after I test for continuity.  Would like to take a look at the thermal fuse since a couple of you believe that's the problem.  Lee
