Bosch KGN34NW3AG 186 cm frost-free fridge freezer: guide and troubleshooting

The KGN34NW3AG is the taller sibling of the KGN33NW3AG: the same 60 cm footprint and frost-free design, but 186 cm high. The extra height mostly goes into the fridge compartment, which makes it a good fit for families who buy a lot of fresh food.

Before you install it
At 186 cm the KGN34 is taller than many gaps under wall cupboards, so measure the opening height carefully and add the ventilation clearance listed in the installation instructions. Check door swing as well: the doors need room to open past 90° for the drawers to slide out fully. After moving the appliance, let it stand upright for a few hours before switching on so the compressor oil can settle.
Troubleshooting
Running constantly
A fridge freezer that never seems to switch off is usually working harder than it should. Check that the doors close and seal properly, the room is not unusually hot, the back of the unit is not pushed against the wall and the condenser area is free of dust. If temperatures are still rising, a fan, thermostat or sealed-system fault is likely.
Water in the bottom of the fridge
As with other frost-free models, a blocked defrost drain at the back of the fridge compartment is the usual cause. Flush it gently with warm water.
Door seal not closing
Seals can become hard or distorted over time. Cleaning them and warming them gently with a hairdryer on a low setting sometimes restores the shape; a torn seal should be replaced.
Temperature alarm after a power cut
A temperature warning after a power cut or a long door opening is normal. Keep the doors closed and allow the temperature to recover before checking the food.
Verdict
The KGN34NW3AG is worth the extra height if you regularly run out of fridge space. Like any frost-free fridge freezer it benefits from simple care — clean seals, a clear drain and room to breathe — and with that it should give 10 to 15 years of service.
Questions owners ask
- Is the KGN34 bigger than the KGN33?
- Both are 60 cm wide. The KGN34NW3AG is about 10 cm taller (186 cm against 176 cm), and the extra height mainly adds fridge capacity.
- Why is my fridge freezer running all the time?
- Check that the door seals close fully, the back of the unit has space to ventilate, and the condenser area is free of dust. Constant running with warm temperatures can point to a fan or sealed-system fault that needs a technician.
- How long should a Bosch fridge freezer last?
- With normal care a modern fridge freezer typically lasts 10 to 15 years.
