LG fridge freezer CF error code
What CF means on an LG fridge freezer
Condenser fan fault.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On an LG fridge freezer, the CF code means there is a fault with the condenser fan. This is the fan that sits beside the compressor at the back of the appliance. When it stops working, you may notice the fridge or freezer not cooling properly, louder noises than usual, or the electrics tripping. Engineers also sometimes find the sides, back or door seals of the appliance feeling very hot.
Engineers sometimes find the fan motor has seized and will not turn at all. Sometimes they find a fan that still runs but has become noisy, which can come and go, so the appliance may seem fine one day and show the code again later.
An engineer will usually check whether the fan is getting power and whether it actually spins, and test the motor itself. The usual repair is to fit a new fan motor, sometimes together with a new fan blade, then run the appliance to confirm the fan is spinning quietly and the compressor is running. The replacement fan often has to be ordered and fitted at a second visit.

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.
