Suspected broken fan prevents top fridge section cooling down

Call them out under warranty. the circulation fan is normally at the back of the fridge. On such a new fridge, so shouldn't need to be fixing issues. A fan is an 'electrical component', not an electronic item.

NORMALLY, wine fridges have two sections, Upper Section for chilled white wines and Bottom section for red wine cellaring. In your case, they are reversed, but is definitely dual zone.

Hello Tonytonz953,

I understand that you are needing to change the fan on your refridgerator. The fan is loacted in the freezer section and has an outlet that blows in to the fridge compartment. You can order the fan at the following link http://www.ransomspares.co.uk/parts/search/fan-/bosch/fridges-freezers/kgn33v00gb%2f06/b/c/m/ this is the cheapest on that I could find and the cost is 75.85 pounds.

Thank you for choosing FixYa.com

Well nobody came up with any other options so I guess it's just defrost a "nonfrosting" fridge every three months or so, just like the old days.
No progress here then in spite of advances? in technology.

It sounds like you may have a bad evaporator fan motor or broken blade.

Another cause could be a failed defrost system component. The would cause a build up of ice and frost and the fan blade could be coming in contact with the frost or ice.

The fan stops running when the doors are opened on this model to prevent the circulation of warm air.

You might try removing and ohming out the door switches before you remove the fan motor. for fan motor operation the switch should read open on the NO to C and closed on NC to C with the switch out of the fridge. push and hold in the switch and the opposite readings should be observed IE closed on NO - C and open on NC - C. look closely at the switch for these letters.
If you have an electronic control system with an led or lcd display a magnetic switch may be employed and this would do both operations with a magnet close to the switch acuator.

I have the same freezer and get the same problems. Ice forms on the refrigeration fins beind the plastic shroud at the rear and completely blocks the airflow. The fan that moves cool air around does not work then and freezer temp goes up. Ice will often push the shroud forwards so that the door does not close properly. Warm moist air get in and just increases the ice problem.

I take the shroud and fan housing off the rear (4 screws and a wire to the fan) and defrost thoroughly using a hair dryer. You can then see when all the ice has gone..

confirm your model number by getting it off the serial plate then go here http://www.boschappliances.com/site_tools/DocumentDisplay.aspx?menu_id=27&menulevel=0302&keyword=KGN33V00GB

Hi - experienced this myself and spent ages trying to get to the bottom of it - only found one post but it worked and was absolutely clear on the cause nb: i'm not an "expert" !

My understanding of how the Bosch f/f works is that the freezer compartment generates the cold air for the fridge which is regulared at the fridge end . At the back of my fridge there are two "vents" which feed up this cold air up from the freezer into the fridge.

Problem happened to me because I left the freezer door slightly ajar which generated a massive amount of frost (sucking in the moist air from the house I guess then freezing it) and subsequent ice froze up the cooling ducts between the freezer and the fridge. Therefore, no matter how much I turned up the fridge thermo it never got cool. Only solution was to dump my frozen at a mates house and defrost the the FREEZER for a good 24 hrs +.

Worked tho' - fridge was completely back to normal.

PS: I understand this issue may also happen if you put too much unfrozen food into the freezer at one go and in working overtime to get it frozen causing a massive frost up again.
