Bosch fridge freezer freezer not freezing?
Hoping someone can help with my Bosch fridge freezer — the freezer has stopped getting cold and everything inside has defrosted. Is this a common fault on these?
1 Answer
If the freezer has fully defrosted, the fault is usually one of a few common areas rather than anything model-specific. On Bosch frost-free fridge freezers, the usual suspects are poor airflow, a defrost problem, a fan fault, or a sealed system/compressor issue.
Before checking anything internal, isolate the appliance from the mains.
1. Check the basics first - Make sure it hasn’t been put into a holiday/demo mode or had the temperature altered. - Listen for the compressor at the back/bottom. Is it running constantly, clicking on and off, or completely silent? - Check whether the fridge section is still cold or if both sections are now warming up.
2. Look for frost build-up inside the freezer - Remove drawers and check the rear internal panel. - If there is heavy ice/frost behind or around the back panel, that points towards a defrost fault or evaporator fan problem. - If there is no frost at all and it is running but not cooling, that can indicate a sealed system/refrigeration fault.
3. Check the fan - On frost-free models, if the evaporator fan stops, cold air will not circulate properly. - You may hear no fan noise when the door switch is held in.
4. Inspect door sealing and ventilation - Make sure the freezer door seal is intact and the appliance has good airflow around the condenser area.
If it has defrosted completely and the compressor is running but there is little or no cooling, I’d be thinking more seriously about a refrigeration system fault, which is not a DIY repair. If you can say whether the fridge section is still cold and whether there is frost on the back freezer panel, that will narrow it down a lot.
For any mains, sealed refrigeration, or advanced internal testing, it’s best to use a qualified engineer.
