What Does Error GF Mean?

The LG refrigerator GF error code indicates a flow sensor issue, often linked to low water flow affecting water dispensing or ice production. Users may notice the GF code on the control panel without immediate cooling failure. Common causes include a defective flow sensor, low water pressure, or wiring problems between the sensor and the main board. Addressing these issues promptly can prevent further complications.

Common Symptoms:

  • GF code displayed on control panel
  • Possible issues with water dispensing or ice maker water flow
  • Refrigerator display panel showing error without cooling failure

Possible Causes

  • Defective flow sensor (medium)
  • Low water pressure or restricted water line (medium)
  • Wiring issues between flow sensor and main board (low)

How to Fix Error GF

DIY Fix Check water line and basic flow issues

  1. Turn off water supply to the refrigerator and inspect the line for kinks or visible damage.
  2. Ensure water pressure at the supply source is adequate (normal household pressure).
  3. Replace water filter (if applicable) as a clogged filter can reduce flow.
  4. Plug refrigerator back in and check if GF error clears after cycling power.

Technician Only Diagnose and repair flow sensor and related wiring

  1. Disconnect power and access the flow sensor assembly (location varies by model).
  2. Test water flow sensor continuity and signal output with multimeter.
  3. Inspect and test wiring harness between sensor and main board for opens or shorts.
  4. Replace faulty flow sensor if tests show failure.
  5. Re‑assemble and test the refrigerator for correct operation.

Parts needed: flow sensor assembly, wire harness connectors

🛑 When to Call a Pro:
  • The GF error persists after basic user‑level checks and power cycling.
  • Water leaks occur near the base or water supply line.
  • Signs of electrical issues (burning smell, panel unresponsive).
