Liebherr Fridge (KES3660) is freezing at the bottom (bottled water turns to ice) and too warm at the top. The internal ventilator fan does appear to work as sometimes it is spinning when the fridge door is opened; or at least we got it spinning when we turned it on via the vent fan button. I'm guessing that there are sensors top and bottom to control when the compressor cools and when the fan mixes the internal air. I would assume one of the sensors has goon wrong with the result that the rrige is now no longer automatically turning the fan on. Question is "would you agree with diagnosis" and what is the chances of my purchasing the parts and replacing myself?

thermostat is faulty - supercool just bypasses the stat

that is the normal operation

Try these solutions in these order:
1. Switch off the fridge and leave the door open overnight. Switch it back on in the morning.
Explanation: The sensor inside the fridge gets frozen and cannot control the temperature properly.
2. Switch off the fridge. Unplug it. At the back of the fridge (behind the unit, not inside) there is a large grid. Clean it with a hoover thoroughly. Open the fridge. Dry the back of the fridge if wet (inside the fridge). If frosted wait for it to defrost and then dry it. Plug in the fridge. Switch the fridge back on. This one worked for me.
Explanation: The dust in the grid deprives the fridge from cooling down and the unit can't control the temperature in the fridge section.
3. Switch off the fridge. -Unplug it. Empty it. Turn it upside down. Plug it in. Switch it on for 24 hours. Switch it off. Unplug, return to normal and switch on.
Explanation: This has to do with the pressure of the gas inside the compressor. I have not tried it but this advice as given to me by a qualified electrician when I commented the (in)famous F2 problem in Liebherr fridge/freezers.
Hope it helps. Regards. Albert

The ventilator fan causes the water to evaporate from the drain pan. There may also be a heater element to do it as well. Without it nothing is making the water evaporate so it is overflowning. Might be the fan motor or the switch that is a problem.

Hello,
Normally if you remove the LHS salad drawer in the fridge you will see a sticker on the wall of the unit with the relevant information.

Hope this helps.
