Liebherr fridge/freezer fridge started warming up until a point when it stopped cooling all together. We switched it off for months and just before dumping it we switched it back on. It reached the desired temperature and it has been working for months now. We left a termometer in the fridge to keep an eye on the temperature. it is suppossed to be 4C but it is usually 6C and sometimes it cools down to 2C sometimes it warms up to 8C. The temperature varies so we are loading it very carefully and dont leave it open for more than a few seconds. If we leave it open for a minute or two it takes days to be back to normal.
At this point I am wondering if we change the thermostat would it work fine again or can anyone suggest a solution.
