In your case I will need to assume that your model is a typical refrigerator with a defrost control and these type have parts that are made up of the major parts for the auto defrost. Auto defrost has a most likely problem found in the timer or electronic defrost control. These are most times found inside the fresh food section and behind the temperature control panel in the photo below marked a E and in that photo it shows a defrost timer in lower arrow and a electronic defrost control in the upper arrow. The next most likely problem would be the defrost heater and defrost thermostat found in the rear of the freezer compartment. Sounds like the defrost system has failed. Most Brand models We are able to handle here in the USA but your model is made ih the UK and I have tried my best to Have your dealers provide me information about parts replacement. A refrigerator is a Refrigerator and that is a fact but your models is designed for your local voltage 220 volt at 50 cycles That is normal home voltage in most countries except th USA. Our voltage for an appliance is 120 volts at 60 cycles so all the electrical components ar different and made different for different countries. When I request parts or diagrams from the UK I am always rejected. Then given a local repair center to service the brand of appliance.

    Sometimes you can find the defrost timer and turn the timer dial in center of the timer slowly clockwise and cause the refrigerator to go into defrost. You may see a small hole in the control panel where the temperature controls are and at times there is a plastic plug covering the hole to hide the opening. Remove the plug and slowly turn the timer clockwise until the refrigerator compressor stops. Leave the refrigerator like that for 25 minutes and if it does not restart on its own then slowly turn it again clockwise until the compressor restarts. If you need to do this then the timer is defective and will need replaced. During this time off the freezer should be in defrost and open the freezer door to listen to hear if there is crackling and sizzling. That would be the sounds of the defrost heater melting the ice inside and behind the back of the freezer wall. If you hear nothing and the refrigerator does not defrost then the defrost heater and defrost thermostat will need replaced. Letter C in photo is the defrost heater and the defrost thermostat is connected to the defrost heater. If you would tell me your location in the UK I will try to locate the supplier of the parts for your model. I really hope this information helps you, If you have more questions or need help feel free to let me know,If this helps answer your question please rate my solution, Thanks, Sea Breeze

    Because yours does not have the freezer then the thermostat is most likely your problem. It would be stuck on as cold as you can set it. But even coolers must defrost because they will begin freezing if the control does not turn it off.

Bosch kann58a50gb/o8 fridge not cooling freezer seems ok

See or hear if the fan inside is working. Im not conversant with your model. Some units have 2 fans , 1 in the freezer and 1 in the fridge. Some only have1 , which will be in the freezer only. If the fan fails, the fridge cannot blow cold air into the food compartment. Generally, when an evaporator fan fails, the fridge doesn't get cold and the freezer overfreezes causing an excess ice buildup in the freezer.

If you have a refrigerator or a freezer that is not working like it once did then you are looking to get it working again. The reasons why he unit may not be working properly can be many. One of the reasons may be that the refrigeration unit that is the cooling power of the unit is slowly leaking refrigerant.

If the refrigeration unit is leaking very slowly the loss of charge may be so subtle that you will not notice it till the unit basically stops cooling completely. Then all of a sudden you realize that you have a problem. If this is your problem, you will notice that the compressor is running, the circulating fan(s) will be running, and the condenser fan is running. Everything appears to be perfectly normal, but you are not getting the cooling from the unit that you need.

If you have this situation then there is often not that much that you can do. To recharge the unit you will need to find a technician that is certified to handle refrigerants. The system which is charged and sealed at the factory will have to be tapped and the proper refrigerant added to the unit. Even then you still have a system that is leaking and the fix will only be temporary. Sometimes the leak point will be obvious, other times the leak may be very difficult to find. Most of the time, the leak will be next to impossible to find and repair.

Bottom line here is that you will have to make some hard decisions about the repair of a leaking refrigerator or freezer. If you get refrigerant added to your unit it will be a temporary fix. If you can find the leak and it is repairable, you will have a bill for that repair also. That bill may be more then the unit is worth if it is a basic model or an older model. In many cases the purchase of a new unit may be the best option.

I have got a Bosch KGV36NW20G Fridge Freezer and it's only 2.5 years old. Some problem has occurred recently. I can hear that water or some fluid is flowing around in the Fridge Freezer all the time, which...

From your description, it sounds like your condensing coil is dirty and needs cleaning. You will probably find the coil and fan inside the back cardboard cover area. Once a condensing coil gets so dirty, the refrigerant condensed in the condenser is so hot that it does little cooling effect because of the internal heat consumes any refrigeration effect left in the refrigerant. This is vary common problem and especially for pet owner. The pet fur and hair get caught in condensing coil and block air flow.
Hope this helps

most fridge-freezers send cold air from the freezer to cool the fridge. the flow is usually controlled by adjusting a 'warmer-cooler bar or wheel in the fridge. maybe you disturbed its original position while working on the fan.

Once the fridge is shut OFF for few hours to defrost and then switched ON , if the fridge works with cooling , then the fault is with the AUTO DEFROST TIMER or the circuit -maybe the heater, break in the lines to the timer, heater, the fan.
The build up frost will block the flow of cool air to the fridge from the freezer evaporator.
So remove and check.

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.
