My refrigerator is giving me some error codes.
For example, on the door’s touch board it keeps giving me the code Er dH.
It doesn’t let me do anything on the touch board.
I really need to know what this code means because I need to fix my refrigerator.
It’s a side by side LG refrigerator.
PLease and Thank you.

You have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer.
dH looks like an open defrost heater error.
Try unplugging the unit for 10 minutes or so to see if it will clear.
Try forcing a defrost cycle to see if the defrost heater comes on.
If not check the heater and the heater fuse.
I think theses are 408A and 400A in Section 3 of the parts but am not sure about the fuse.
If the above are OK then it is probably a control board problem.
