Bosch frost free fridge freezer

I have a Bosch frost free freeer which will not maintain it's temp. The alarm keeps coming on and the temp keeps droping when you put it onto super it will only go as far as 19.then drops again when you take it off I have aquired a new circuit board not sure if it is what has gone but is worth a try but am unable to find where the old one is located so that I can change it. I would welcome any help on this matter

    I have the same problem on a KJU3201gb/01 fridge freezer. Fridge temp stable at 4 degrees, but freezer temp hovers around 2 degress unless switched to super. As soon as super setting switched off reverts back to 2 degrees. Is this a circuit board problem?

The circuit board is fitted behind the display right at the top.

Unplug.
Open fridge, undo the two screws under the display moulding.
Using a thin bladed scraper and a flat screwdiver, prise the panel off at the top join. The top is the only bit with plastc clips, but it will help to apply pressure with the screwdriver at one end as well.
Pull it forward by about 2", and remove the connectors to the on switch.
There may be a drip strip to remove before taking the board out.
Use a thin screwdriver to remove the retaining clip over the board.
Use a small flat screwdriver to lever the board out using he holes at each end.
Observe anti-static precautions as it contains Cmos chips.

Reverse procedure to replace.

Bosch intelligent frost free 88


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 :-(

Bosch KGU44120 frost free fridge freezer (6 years old) generates ice on floor of freezer compartment within a couple of hours. Maintains -20C temperature no problem.


drain is blocked in freezer. take back panel off inside the freezer and you will probably find that the bottom is covered with ice. melt off with a hairdryer and hot water till water flows freely down the drain. needs a bit of patience

Bosch KGU32160 fridge freezer


The compressor behind the fridge should cycle on and off as the machine maintains temperature, but the evaporator fan inside the freezer will keep running, except when the fridge goes into defrost. If the noise is coming from the fan inside the freezer, there could be some ice on the frame of the fan and the blades are touching the ice. If the noise is coming from behind the fridge it could be the condensor fan motor. This fan is situated behind the fridge in front of or next to the compressor. It keeps the condensor cool by blowing air onto it. Check this fan. The blades could be touching the pipework or something.
