Hi

I have an upright Bosch freezer - product codes are: GSU2320GB/52, FD8012, 00804.

The freezer maintains a temperature of 18 degrees C but if the door is opened even for a short period i.e. the time it takes to take out an item, the temperature drops by up to 4 degrees - it then takes 6 or 7 hours to recover back to 18 degrees even with the use of the "super" button. I have defrosted the freezer as per the manual instructions several times now and this has not solved the problem. Why should there be such a rapid drop in temperature when the door is opened? It can't be anything to do with the seals since the freezer maintains its temperature when the door is closed. The other problem is why it takes so long for the freezer to reach 18 degrees again. Are you able to advise on whether the freezer can be repaired or has it had its day?
Thanks for your help
Peter

Thanks for taking the trouble to comment but this is a significant change to the way that it has operated up until now. The room that the freezer is in is not heated and we have not seen the level of temperature drop that we now see. The other issue is the length of time that it takes to regain temp which is far in excess of what it has been.

in all honesty this sounds to be working.IF it hadn't got a display would you be worried?.displays are great but can cause paranoia.get a thermometer and put it in the fridge and freezer and monitor the temperatures.+4 degrees when left overnight in the fridge is normal,-18 degrees in freezer left overnight.During the day and if opening a door in a warm room can be way above this ideal temperature.
Just a thought!
