— LG USA, [LG Refrigerator] Digital and Analog Error Codes. Codes vary by model: check your refrigerator’s own manual.
The same code can also show as: FdH, dHF.
In plain words, dH is about a temperature sensor or its wiring — the control reads a value it does not trust, or a temperature outside its limits.
LG gives 9 other temperature sensor codes for this refrigerator: FS (fault with the freezer temperature sensor), IS (fault in the ice maker temperature sensor), rS (fault in the temperature detection system on the refrigerator side), dS (fault in the defrost temperature sensor), rT (fault in the ambient temperature sensor).
Next to dH in LG’s table: rT (fault in the ambient temperature sensor) and SS (issue in the detection of the water tank temperature).
Safety: If it smells like burning, sparks, or trips the breaker, switch it off at the breaker and leave it off until it is checked.
At least THIS WEEK. fixRAgent treats this code as a this-week repair: the appliance has reported a fault, but the code alone does not point at a safety hazard. This is fixRAgent’s reading, not the manufacturer’s. A photo can raise it — water near wiring, scorch marks, a gas smell — but a code never lowers what the photo shows.
Appliance repair. Have the model and serial numbers from the label ready — a photo of the label works.
Check whether your model is under a safety recall on the U.S. Consumer Product Safety Commission’s site: cpsc.gov/Recalls. Your owner’s manual is on LG’s support site; search it with the model number from the label.
