Er FF

The freezer fan motor is not running normally. In most cases frost or ice has formed around the fan and stopped it turning, typically because the freezer is overloaded or a door was left slightly open. If there is no frost at all, the fan motor itself may have failed.

Difficulty

Start with the safe checks below; a worn part may need replacing.

Safety first: unplug the refrigerator (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG Er FF

  1. Try a power reset

    Unplug the refrigerator or switch off its breaker for about 5 minutes, then restore power. If the code clears and stays away, keep an eye on it.

  2. Empty the fridge and prepare for meltwater

    Move food to another refrigerator or an insulated cooler, empty the ice bin, and lay dry towels on the floor in front of the doors.

  3. Defrost with the power off and doors open

    Unplug the refrigerator and leave both freezer and fridge doors wide open for at least 24 hours. LG says it can take about a day in summer and up to three days in winter, depending on how much ice there is. Let the ice melt naturally: do not use a hair dryer or heat gun, which can warp plastic parts or start a fire, and do not chip ice with knives or other sharp tools.

  4. Dry, restart and check the doors

    Wipe the interior dry, plug the fridge back in and allow 24 to 48 hours for it to reach normal temperatures. Avoid overpacking the freezer and check that the doors close and seal fully.

When to call a technician

If Er FF returns after a full defrost, or there was no frost on the freezer walls to begin with, request service; the fan motor or defrost system likely needs a technician.
