I have bosch classixxKGU34640GB/05 frost free fridge freezer. the freezer food had defrosted and fridge was also warm. alarm red light was on. the light and fan in fridge was working. it is in very good condition but i think it must be 8 - 10 years old. has it died of old age or is it something relatively simple as thermostat, electrics or worse still the condenser? any advice much appreciated. thanks

the freezer is not defrosting at all .How to defrost it ?

The small drain pipe on the back of the fridge gets clogged, hence no drainage when defrosting, hence ice blocks the airflow between the freezer compartment and the fridge compartment.
Remove the rubber stop from the drain pipe and clean (can be found above the motor)
Defrost the fridge for a few days (it takes at least 48 hours). During this time, if you are not brave enough to remove the internal panels of the freezer and continually clean the water, check for water coming out and clean.
If during the defrost there is no water coming out the drain pipe, use about 2m of flexible and strong wire to clean the pipe.
The aim is to unblock the pipe once the ice has melted.

We have the same and I think it is because the freezer door bounces open when we shut the fridge door. Then the freezer compartment ices up, the fan clogs up with ice and cannot blow cold air into the fridge, and the fridge gets warm and the milk goes off.
Solution? We have bought one of those child safety clips (search for fridge safety clip or lock) to hold the freezer door closed.
Simple design error. Expected better from Bosch :-(
