Kenwood fridge freezer E4 error code
What E4 means on a Kenwood fridge freezer
Fan motor fault.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On a Kenwood fridge freezer, the E4 code means there is a fault with the fan motor. You may notice it alongside a noisy appliance, often a loud vibrating or droning sound from the freezer, or a freezer that is not freezing as it should.
Engineers sometimes find that the freezer fan motor itself has worn out or failed mechanically, so it makes a loud noise as it spins. The noise may stop when the freezer door is opened, because the fan pauses while the door is open.
An engineer will usually empty the freezer, take off the inner cover to reach the fan, and check for ice around it. They will also test the defrost parts and listen to the fan running. If the fan motor is at fault, they replace it. The new motor often has to be ordered and fitted at a second visit. Once the new fan is working, the freezer can take up to a day to get back down to temperature, and it is best not to use the appliance until the repair is done.

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.
