LG fridge freezer FF error code
What FF means on an LG fridge freezer
Freezer (evaporator) fan fault.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
When your LG fridge freezer shows the FF code, it is telling you there is a fault with the freezer fan, the fan that moves cold air around inside the appliance. You may notice the fridge or freezer is not cooling properly, the freezer is not freezing, or the appliance has become noisy.
Engineers sometimes find the fan blade has stopped and will not turn when the appliance is switched on, and sometimes find the fan has broken mechanically and is rattling loose on its motor, which can cause a loud rattling noise while it runs.
An engineer will usually clear the freezer shelves and look at the fan behind its cover to see whether it is turning freely and whether the blade or motor has failed. The usual repair is to replace the freezer fan motor, and sometimes the fan blade as well. These parts often have to be ordered, so the repair is commonly finished at a second visit, after which the engineer checks the fan is spinning and the code has cleared.

Before you check anything yourself
- Switch the fridge freezer off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the fridge freezer apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
