LG Er It

LG error code ER IT indicates: On LG Refrigerator: Icemaker unit Failure (icemaker unit motor problem) / ABNORMAL ICE-MAKER UNIT.

The primary root cause for LG code ER IT is: On LG Refrigerator: Icemaker unit disconnection, an icemaker unit motor or hall IC damage, a defective Main PCB, lead wire short&open circuit, or faulty motor driving circuit..

To resolve error code ER IT: On LG Refrigerator: Unplug the appliance and wait for 20 seconds, then restart. Check if the connector at the PCB or icemaker is removed or loose, then re-insert. Check if the connector measures 18 ~ 22 W between motor connections. Replace the assemblies if the problem is not solved.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if LG code ER IT persists, the physical component causing On LG Refrigerator: Icemaker unit disconnection, an icemaker unit motor or hall IC damage, a defective Main PCB, lead wire short&open circuit, or faulty motor driving circuit. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
