In Europe the modern fridges & freezers have hidden sensors that make sure the motor does not go on whilst the door is open, even if the temperature has dropped. So basically, when you close the door, you are basically switching the fan on!
Some electricians make a point to know how to sort this.
The sensors are magnets in the door and main body of fridge, so sticking a magnet to the door or actual fridge will usually solve this. Some models need two magnets.
Taking the bulb out does not solve this problem. Obviously the good old fashion time switch will also be ok..
