LG Error Codes & Diagnostics

1. Unplug the appliance and wait for 20 seconds. 2. Restart the appliance. Repair Instructions: Check if the connector at the PCB or inside the freezer is removed or loose (re-insert). Check if the connector measures out of 1 ~ 150 kilo-ohm range (normal is 3.1 kilo-ohm at 20 degrees Celsius). Replace the assemblies if the problem is not solved.

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.

1. Unplug the appliance and wait for 20 seconds. 2. Restart the appliance. Repair Instructions: Check if the connector at the PCB or inside the refrigerator is removed or loose (re-insert). Check if the connector measures out of 6 ~ 300 kilo-ohm range (normal is 13 kilo-ohm at 20 degrees Celsius). Replace the assemblies if the problem is not solved.

Inspect fresh food fan motor and clear ice. PRO TIP: If your fridge is showing any 'E' code and it's under 5 years old, always try a hard reset (unplug 10 minutes) before calling. 60% of the time it clears temporary glitches.

Unplug the appliance and wait for 20 seconds, then restart. Check if the connector at the PCB or inside the refrigerator is removed or loose, then re-insert. Check if the connector measures out of 6 ~ 300 kilo-ohm range (normal is 13 kilo-ohm at 20 degrees Celsius). Replace the assemblies if the problem is not solved.

Unplug the appliance and wait for 20 seconds, then restart. Check if the connector at the PCB or at the hinge is removed or loose, then re-insert. Check if the connector measures out of 5 ~ 400 kilo-ohm range (normal is 13 kilo-ohm at 20 degrees Celsius). Replace the assemblies if the problem is not solved.

1. Disconnect 230V mains power for 3 minutes. 2. Inspect wire harness and edge connectors on control board for loose pins or oxidation. 3. Inspect mechanical linkages and sensors associated with subsystem. 4. Reset: Press Power to turn off. Unplug mains cable for 5 minutes. Press and hold Start/Pause for 10 seconds to discharge board capacitors, then restart.

Likely a stuck water inlet valve. Replace valve assembly. PRO TIP: We see more clogged pump filters than any other single issue. Takes 5 minutes to clean and saves a $149 service call.

Unplug the appliance and wait for 20 seconds, then restart. Check if the connector at the PCB or machine room is removed or loose --> re-insert. Check if the connector measures 7 ~ 16 VDC between Black and Red Connections or 1 ~ 4 VDC between Purple and Red Connections. Replace the assemblies if the problem is not solved.

Unplug the appliance and wait for 20 seconds. Restart the appliance. Check if the connector at the PCB or inside the freezer is removed or loose, re-insert. Check if the connector measures out of 1 ~ 150 kilo-ohm range (normal is 3.1 kilo-ohm at 20 degrees Celsius). Replace the assemblies if the problem is not solved.

Often caused by a faulty rotor position sensor (hall sensor) or overloading the washer. PRO TIP: We see more clogged pump filters than any other single issue. Takes 5 minutes to clean and saves a $149 service call.

Unplug the appliance and wait for 20 seconds, then restart.

Check the breaker box, heating element, or thermal fuse. PRO TIP: 'Flow Sense' or restricted airflow errors mean you must clean the vent — this is the #1 fire hazard.

Clean the drain pump filter, clear drain hose blockages. PRO TIP: We see more clogged pump filters than any other single issue. Takes 5 minutes to clean and saves a $149 service call.

1. Unplug the machine. 2. Remove the top panel. 3. Check the thin tube connected to the pressure switch for blockages. 4. Replace switch if tube is clear.

Restart the appliance, and restart a cycle.
