Common LG Fridge Issues We Resolve

Our refrigeration technicians diagnose and repair these frequent symptoms on-site.

Compressor Running But No Cooling

Symptom: LG inverter compressor hums softly, but neither compartment achieves refrigeration temperatures.

Cause: Micro-leak in copper evaporator tubing or discharge line, or choked capillary filter drier.

Essentechs Solution: Nitrogen leak sniff testing, brazing leak points, filter drier replacement, and pure R600a recharging.

Error Code Er FF or Er dH on Display

Symptom: The control panel flashes Er FF (Freezer Fan) or Er dH (Defrost Heater) and beeps.

Cause: Ice blocking the freezer fan blade, defective fan motor hall sensor, or burnt defrost heating sheath.

Essentechs Solution: Manual de-icing of coil box, motor replacement, and testing defrost controller relay.

Loud Humming or Buzzing Noise from Rear Bottom

Symptom: Excessive vibration noise that stops briefly when the refrigerator door is opened.

Cause: Dust-packed condenser fan motor blade rubbing or worn compressor mounting grommets.

Essentechs Solution: Condenser deep clean, fan motor shaft alignment, and rubber isolator pad replacement.
