LG Refrigerator Error Code FF: Troubleshooting Guide

When your fridge experiences a problem with its cooling system, you have to get it fixed immediately to protect the items you keep inside it. A perfect example is the FF error code on an LG refrigerator which points to a freezer fan problem.

The FF error code on an LG refrigerator means there’s a freezer fan problem. The issue is most likely triggered by an ice buildup at the fan blades, a failed fan motor, or a problem with the main control board. Once the problem is resolved, give your fridge 24 hours to stabilize itself and reach the temperature you’ve set for it.

The following sections will explain the problem, its causes and solutions in more detail for you to understand.

When you see the FF error code on your LG refrigerator display, that means there’s a problem with the freezer fan. In particular, the evaporator fan in your freezer is affected.

The evaporator fan plays a critical role as it helps to distribute cold air to wherever it’s needed. For example, in your freezer, the fan will drive cold air to all corners of the compartment, ensuring that all your food items are frozen evenly and kept that way for as long as they’re stored inside the unit.

The FF error code is most likely triggered by an ice buildup around the affected fan, a failed fan motor, or a faulty main control board. This section will help you understand each of these possibilities and what you can do to fix them.

Ice Buildup Around Fan

What it is: The evaporator fan turns on and off repeatedly. When the freezer is too warm, it’ll turn on and distribute cold air throughout the compartment. But when the set temperature has been reached, the fan will turn off until it’s needed again.

The fan blades must always be able to turn freely without anything obstructing its movement.

How it fails: Ice and frost can build up around the evaporator fan over an extended period. That typically happens because warm air and moisture enter the compartment, such as when the door is left open for too long.

As that ice buildup becomes larger, it will eventually block the path of the evaporator fan blade. When that happens, the fan blade can’t turn and will trigger the FF error code that you see.

How to fix it: The most effective way to remove an ice buildup is to let it thaw out naturally. You can do this by emptying the freezer and leaving the door open while keeping the LG fridge unit turned off. 

Remember: this process can take quite a long time, depending on how big you have an ice buildup.

Failed Evaporator Fan Motor

What it is: The evaporator fan is powered by a fan motor that turns on and off as needed for the freezer to reach its set temperature. Whenever it receives electrical power and signals from the main control board, the fan will turn and blow cool air as it’s supposed to.

How it fails: The electrical evaporator fan motor can fail due to an electrical fault or from excessive wear. For example, an electrical surge like those during a thunderstorm can cause the motor to short out and stop working.

Besides that, any obstruction to the fan blades (like the ice buildup mentioned earlier) will force the motor to work harder than usual. When that continues for too long, the motor will experience excessive wear and burn out.

How to fix it: When an evaporator fan motor fails, it must be replaced with a new one. Always unplug your LG refrigerator before any repairs, for safety reasons.
