Question about Refrigerators

Fridge working intermittently.

I have a Bosch fridge freezer. The Freezer is fine but the fridge is not getting down to temperature and light is flashing most of the time when set on 4. Occasionally it does get down to temperature and the light goes out.

Hi,

Based on your post/description the freezer is working as expected. A few basic/working ideas:

  • most designs call for a single compressor to cool the freezer;
  • the cold air in the freezer is drawn towards the fridge to cool that area;
  • this is performed by a fan drawing air in the freezer through the evaporator;
  • most would have a vent or air pathway to guide the freezer air;
  • all would have thermostatic control to set the desired temperature;
  • some designs have two thermostatic control , 1 for the freezer, 1 for the fridge.
As applied to your concern:
  • compressor is working since freezer is OK;
  • pls verify that the fan is turning drawing air from the freezer side to the fridge side;
  • additionally check that the air is strongly blown into the fridge area;
  • a little experiment, open the fridge door, look for and press on the door switch, the light should go out, after a lengthy seconds, the fan should trigger on, not only would it be audible, you would notice the frozen air swirling inside the fridge area. If you hold on long enough to the dorr switch, the compressor should kick in (if it is not already running) since the thermostat of the fridge area (if one is present) would sense that the fan is turning but the fridge area is not cooling.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Sir/madam,

Order the thermostat.

Re-placing the thermostat.

TURN OFF THE POWER. Empty the fridge.
Remove the door using the star key on the two bolts at the top of the hinge. Do this with the door shut whilst the hinge is undone, then gently lift the door off over the light cover in the top of the fridge.

The thermoststat is behind the temperature control in the control panel at the top of the fridge. The coin operated 0 – 7 control on the right.

Remove the light cover by turning it leftwards and gently pulling it away.

Using a fine screwdriver or knife take the three covers out of the control panel. Behind are three bolts with the same size head as the door bolts. Remove them.

Remove the temperature control knob, or let it will come off as you take off the control panel cover. Gently ease the control panel off. It will probably be a bit caught on the thermostat probe tube.

In the back of the fridge is the cooling panel. Slacken off the two cross head screws which are clamping the thermostat probe to the back of the cooling plate.

Use the flat head screwdriver to push in the four spring loaded catches holding the cooling plate. Push in the sprung nob and whilst doing that pull the cooling plate of the mounting post (firmly but carefully). When you have undone the last one the plate can be swung aside to reveal the thermostat tube, unclip the tube from the back of the cooling plate and at the control panel withdraw the tube from where it goes into the top of the fridge. As you pull it out it will get stuck on any bends in the pipe behind the cooling plate so straighten it as you go. You can now cut off the tube if it is getting in the way.

The thermostat cycles the refrigerator on and off.
The refrigerator normally runs as long as the temperature inside the refrigerator is higher than the set temperature.
If the temperature inside the refrigerator is cold enough and the thermostat still does not cycle off, the thermostat may be defective.
If so, you need to replace it, because it cannot be repaired.

If the thermostat is not defective, you may have a problem with the sealed (refrigerant) system, in which case you should contact a qualified appliance repair technician.

Sir, it must have been freon problem about the temperature or some switches and about the light just replace with a new one. better to bring to the repair service to have replace the freon and the light bulb too. if your fridge is cover on warranty then send it to the place where you bought it for a free service. hope that helps.

Bosch KGU 34640 freezer not cold enough


I had a similar problem a couple years back with my freezer. Behind the vent cover in the back there were a few lines that ran the cooling or something like that. What happened was my freezer was icing up horribly. I was told to take that panel off and check those lines. Sure enough one of the lines was busted through. That was why my freezer was having problems. I apoligize I don't know anything about the front buttons tho.

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 Fridge freezer will not work


This is a Solution posted by a guy called Sandy Small in october 2005 and believe or not it works

Repair to Bosch fridge freezer KGV3104GB

This MIGHT be the same as yours!

Detach top panel above fridge door and "hinge" it down towards you attached to its connecting wires. See if the connector on the right has a thick black wire (nearest the fridge) and two brown wires. The faulty fridge temp. sensor can be shorted out by connecting the black wire to the brown wire next to it. I managed this by bridging the corresponding points on the PCB with a blob of solder. My fridge freezer works OK now on the freezer sensor. Hope this works with yours!

FREEZER WORKING - FRIDGE NOT WORKING


Ok, got it sussed! [well here's what I did anyway]...

Quite simply, I turned off the fridge-freezer at the mains overnight and in the morning, broke and chucked out the ice chunks that had lined up in the bottom of the freezer section and then turned it back on. I returned that night to see that it was working fine again! Hallelujah, I got my fridge back!!

So it seems that all it needed was a good long defrost, so far so good! I hope this solves your problem.

Bosch Fridge Freezer Classixx


This button is the winter/summer setting.
If you switch it on so as the red mark shows this is set for the summer setting.
What it does is allows the interior light to come on very dimly when you shut the door.
The fridge then thinks it is too warm and starts to cool down more, designed for when the ambient temperature is high.
Hope this helps
