The thermostat was open circuit all the time and was replaced. It is now working correctly. I still can’t see a coolplus button. Thanks for the pointers.

Thanks for the replies.
The fridge is in a kitchen with a temperature of about 22 degrees.
I can’t see a coolplus switch on the instructions or the picture she sent me, where is it?

Re: Liebherr CUN 3031 not cooling

Hi again!
I took the cover off the fan before defrosting and there was a large build up of ice on the pipes and evaporator. The freezer was left for a day and had fully defrosted.

So far so good. The fridge dial is now on 4 out of 7 and the fridge stays between 3 and 5 degrees. The freezer lies between -21 and -25 (does that sound okay?)

It sounds like the fan is running for longer/faster as previously when you opened the freezer door the fan stopped immediately. Now when you open the door, the motor stops but you can still see it spinning as it comes to a stop.

Thanks ELDAR59 for your help :tup: with this saga and fingers crossed that is the end of my freezer woes. 🙂

Re: Liebherr CUN 3031 not cooling

Hi,

I managed to order the PCB from Liebherr with a couple of white lies 🙂 It arrived first thing this morning and was fitted by 10am.
My block of ice in the freezer started to cool from its regular -10 downwards and I thought our problems were solved… It got as far as -14 but since then it has hovered about -11/-10. The ice cream is still not solid 🙁
The dial is on 5 out of 7 in the fridge and it sits between 3 and 5 degrees. The fan spins and I haven’t heard it pulsing all day.

Help!!

By this site do you mean UKwhitegoods?
If so, then no I haven’t.

Re: Liebherr CUN 3031 not cooling

Hi ELDAR59,

Just off the phone to Liebherr and they say they will not sell the PCB to me. They will only sell to electrical companies/engineers.
Any suggestions of how to get it?

thanks,
Chris

Re: Liebherr CUN 3031 not cooling

Hi ELDAR59,

There is no rush, I’ll be leaving early in the morning for a week, so no more freezer dreams for a while.
Thanks again for your help, night night.

Re: Liebherr CUN 3031 not cooling

Thanks ELDAR59,

A part number would be appreciated when you can. Is it easy to change? Any idea on the cost?
The feezer has been steady at -15 +/- 1 degree all day.

Re: Liebherr CUN 3031 not cooling

Hi ELDAR59,
I’ve measured the core temperature of the fridge using a glass of water over the last 24 hours. It’s varied between 3.2 and 5.4 so pretty steady. (There is no fan in the fridge)
I put a small plastic cup of water in the freezer and put a probe in it. The coldest the ice has got is -13 and this morning when I got up it was -8.2. It has slowly dropped back down to -9.5.
I am waiting for a magnet to come from ebay to test the fan with the door open. I’m not sure how often the fan should be running but I can hear it. Sometimes it sounds steady and other times it sounds as if it is ‘pulsing’ ie 5 seconds on, momentarily stops and 5 seconds on etc.
Help!! 🙂

Thanks,
Chris

Ok, understood.

Re: Liebherr CUN 3031 not cooling

I can hear the fan running and it stops when the freezer door is opened. Is it operated by a magnet on the door?
I’ll get a more accurate thermometer and monitor the temperatures of both fridge and freezer the next few days.
How much should the temperatures vary? Is between 4 and 8 degrees normal variations for a fridge?

Thanks again,
Chris

Re: Liebherr CUN 3031 not cooling

Hi,
thanks for the reply.
The fridge seems to be ok, it does vary between 4 and 8 degrees though. Is that normal?
The fan seems to be running normally as well.
Any more ideas? Your input is appreciated.
