What is the coldest setting on an old zanussi fridge freezer 1 or 6

1 on fridges is the coldest --the bigger the number the warmer the fridge
it is the opposite for freezers

could be several things wrong. I'll start with the simplest first. Its possible that you have the thermostat set to the coldest setting. and what his does is actually close off the damper and prevents cold air from entering the fridge. the freezer will be colder because no air is entering the fridge. If you do not have the thermostat set to the coldest setting, let me know and we can go to step 2. at least this way we ca eliminate each step 1 by 1 to get this fixed for you.

fridge coldest setting is 1
freezer warmest setting is 1

check for compresor operation. a relay on compresor could be out

if your freezer can make ice and the ice is dry, the problem is simply air flow into the refig section. A very common cause for a service call that wasnt needed for reefers is the settings. One setting OFF 1-10 usually, operates the compressor. The remaining setting will say , for colder freezer or similar, It opens a little flapper door between the freezer and the fridge section. If you set that one to max or coldest freezer it will actually starve out the fridge section for air ,and you get a cold freezer and warmer box! It happens everytime someone has the problem , its too warm! they peg both controls to coldest! The compressor will coll the freezer sufficiently even if set to 1 and the fridge should be cool too if the setting isnt pegged to coldest setting thus closing down fridge air and making the freezer colder which isnt ever required!

Hi. thanks for the question. # 9 is the high, 1 is low. and it will run for 24 hrs to get on track .thanks the appliance doc

7 is the coldest and 1 is the warmest

i have had the same problem, it was the fan which needed to be replaced.

lower the number, warmer the fridge.
setting 1 - warmest
setting 5 - coldest

this is the same for all fridges

same here. have the znb 4051s refridgerator. freezer works fine but fridge does not. there is no sound eminating from the fridge either...any ideas? its 1 year old!
