SOURCE: Bosch fridge not cooling freezer fine

if back wall of freezer has ice or thick build up you may have a defrost problem or if not the evaporator fan motor could be bad, not moving cold air from freezer to refrigerator.

Hi - experienced this myself and spent ages trying to get to the bottom of it - only found one post but it worked and was absolutely clear on the cause nb: i'm not an "expert" !

My understanding of how the Bosch f/f works is that the freezer compartment generates the cold air for the fridge which is regulared at the fridge end . At the back of my fridge there are two "vents" which feed up this cold air up from the freezer into the fridge.

Problem happened to me because I left the freezer door slightly ajar which generated a massive amount of frost (sucking in the moist air from the house I guess then freezing it) and subsequent ice froze up the cooling ducts between the freezer and the fridge. Therefore, no matter how much I turned up the fridge thermo it never got cool. Only solution was to dump my frozen at a mates house and defrost the the FREEZER for a good 24 hrs +.

Worked tho' - fridge was completely back to normal.

PS: I understand this issue may also happen if you put too much unfrozen food into the freezer at one go and in working overtime to get it frozen causing a massive frost up again.

SOURCE: Bosch Fridge Freezer: Fridge Not Cooling

Your refrigerator's cool is provided by your freezer section through a damper - there should not be excessive frost on the cooling coils - the most common problem is a defrost timer - are you absolutely sure the noise you hear is the defrost this is the first thing to check, defrost control and its components, is it properly shutting off or stuck on during operation - the next thing to check is for possible sealed system problems / small leaks, door gasket seals, etc.

The fact that it started to work once you manually defrosted is the key here - an over forsted evap will cause the problems you describe most commonly - so have your defrost system checked completly and properly - that should solve the problem. followed by checking door gaskets, damper and sealed system - if only part of the coils are frosted as opposed to the entire surface, that usually a clue to sealed system leak - yes 10C is quite warm for a refrigerator. It should be between 34F-40F, optimal is 34F. And freezer section no warmer than 10F, optimal at 0F (-18C)

Hi Genaro,

Blue led light lit solid and yellow led light flashes is an initial attempt of the set to re-light the lamp.Red led flashes and yellow led light solid means that the lamp won't light up that's why it only has sound without the picture.
Since you've replaced the lamp twice and still the symptoms persist, I suspected that the fault came from the ballast board and not on the lamp itself. If the ballast board gone to malfunction, there's no high voltage will produce to light up the lamp and will sensed by the processor and trigger the error code (Flashes/solid led light with color code).

To verify whether the ballast board is faulty or not, check if the lamp will lit by looking through the lamp door louvers at the rear of the cabinet upon turning on the set.
Please let me know what you will find to assist you further.

Hi,


The flashes you've mentioned is a "12" error code which is no error has been detected by the processor.

Double check the error code by following the steps below.


Pressing the front panel "INPUT" and "MENU" buttons at the same time, and holding for 5 seconds,
activates the Error Code Mode.
Note: The front panel buttons must be used, NOT those on the Remote Control.
• The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
• The flashing then pauses for approximately 1/2 second.
• The LED then flashes indicating the value of the *** (ones digit) of the Error Code.
• The Error Code is repeated a total of 5 times.
Example: If the Error Code is "24", the LED will flash two times, pause, and then flash four
times.


Let me know the result.

Very common problem on that fridge and a easy fix: Replace the two big capacitors on the right side of the control PCB 1uF = 0,68uF 250V They lost their capacity causing bad uC supply and this strange LED blinking. Be aware that this blinking can be intermittent and the fridge appears to return to operation. But the uC suffer a lot of internal resets causing intermittent operation stops, low temperature and more not easy recognizable or strange mal functions. So, if You face that blinking normally the capacitors are gone. Some strange and intermittent behaviors of the fridge are also back routed to this PCB - Capacitor malfunction. So enjoy this 30min fix. The capacitors should not exceed US$2 in Your local electronic shop. If You don't want to spend the US$2 You can find the capacitors as a lucky guy in a old PC power supply.
For other more complex problems be aware that the controller board has a very nice and helpful self test option. You go in this mode holding the temperature select button of the refrigerator (not the freezer button) then switch the fridge on and stay on holding the temp button for more 10s. The self test sequence starts in the moment when You release the temp button.
LED 1: Checking sensors (Blinking=OK - Continues=NOK, something wrong)
LED 2: The Flap opens and close two times (Alarm LED shows the open and close position, so the led must go ON and OFF two times in accordance of the detected flap position from the internal reed contact. (So, no action on the Alarm LED no movement on the Flap or a defect Reed contact)
LED 3: Fan goes ON and OFF
LED 4: Drain Heater goes ON and OFF
LED 5: De- Dicer Heater goes ON and OFF
LED 6: Compressor goes ON and OFF
LED 7: End of test sequence - Initializing procedure of normal operation.
Every step takes 30s and the whole sequence take tree and a half minute. Be aware that the alarm LED is no malfunction indicator. It has only the indicator function for the sensors.
The fridge goes in the normal operation mode when he passed the sequence. No further actions necessary.
Be aware that every time when the fridge faced a total power lost he makes a short silent 30s check sequence. If he face a malfunction (Sensors or actuators) he doesn't start the compressor anyway to protect the fridge for further damage!!! So, this test sequence is a nice tool to check that the fridge is in the right conditions to start the working and even so to check the compressor function before maybe a unnecessary replacement .
With a second build in test option you can select and activate devices in the fridge. For this You hold the fast freeze button and switch the fridge on. After 10s release the button and you are in a manual test mode. With the temperature button select the component - Push the Fast freeze button to activate or deactivate. For example: Select LED6 (Compressor) with the temperature button, push the fast freeze button for ON and OFF. But I ask You to be careful on this test mode to avoid further damages. For example a blocked motor that You should release better by hand than blow up by a tricky fingertip. Enjoy this fix and feel free for Crtl C + Crtl V.

I have a Whirlpool Refridgerator model WBM39MS. It stopped cooling and I had it repaired. The Repairman replaced the electronic control box. Repairer claims that the compressor is working. It now seems...


Hi Lollipop, partially working fridge? A fridge either works or not, cold air is made in freezer then distributed to fridge via a vent. In your case WBM Series fridge, top mount freezer blows air down a vent (back centre of chiller compartment). A common fault with the WBM Series is both the PCB and Interface Panel (PCB beside compressor back of fridge, Interface is display panel front of fridge).
So if freezer is cold and fridge not, try a fan motor. If compressor doesn't work either comp is faulty or PCB has blown(has a burning smell).. Hope this helps you and maybe many other ppl.

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.
