Hi!

Please check the "Troubleshooting" part of the manual to a similar LG fridge
https://manualsbrain.com/en/manuals/942858/?page=37

q sinnifica er dh

ER in temp means error code next 2 letters are first letter of part giving problem or where problem located.. if " ER DH" means def heater not coming on, does not mean heater bad but def control bad not letting voltage to heater. could need main bd also

That stands for "error defrost heater"
Even though the refrigerator has gone through a defrost cycle, if a temp sensor does not reach a set temp within an hour, that error will display. You may have a bad defrost heater, defrost relay, thermal fuse, blocked defrost drain,..... something wrong with the defrost system anyway.

The error codes are listed in the service manual (p. 32) at the address below:
LFX25960 Service Manual

"Er dH" seems to be a defroster issue.

it the def t-stat, def. thermistor, or def. fuse whatever lg decides to call it this week that is causing your issue

Hi. You have an Error Defrost Heater. Its taking too long for the heater sensor to open the circuit during defrost. You normally replace the heater, heater sensor and circuit board(motherboard) located on the back of the refrigerator in this situation. Check your mollex plugs and make sure they are connected tightly at the evaporator coil area. Sometimes they come loose. I reccommend replacing the heater and heater sensor located top right on the evaporator coil. This should take care of the problem. Need parts see me on ebay as user, themackshack. Good luck, Mack

That stands for a defrost heater problem. Usually it's the defrost detect circuit that has a blown thermal fuse.

dh error code is a defrost problem. You will need to call a qualified LG technician to diagnose and repair this problem.
