Fridge is warm, freezer is cold

Hi,

I have a problem with my fridge freezer whereas the freezer is cold and the fridge is just warm. This is Zanussi, model is ZRB324NWB.

I have done the following trouble shooting:

1) Checked the fan is working properly (opened the fridge doors and pressed the button which activated the fan) – seems no issue.

2) Defrosted the freezer compartment. However, prior to defrosting I was able to remove the plastic cover which was covering the coils and did not see any significant ice build up at all. That said I went on to fully drain down any water/ice from it.

3) The air flow is not constrained because I used a hairdryer to additionally dry the air ducts and the air flows freely.

4) I put some tape over the small holes that let the cold air into the freezer and I managed to get some air flowing to the fridge (albeit only through one, upper hole). This is a bit of an intermediate solution though, as clearly the air in this case it not flowing properly to the freezer.

I will get a multimeter this evening to check for any faults:

– the freezer temperature fuse
– defrost thermostat
– refrigerator thermostat

Is there anything else anyone can imagine could have gone wrong?

I was reading about the possibility of fridge freezer defrost timer, but I am inclined to discount this possibility as this apparently results in high ice build up and I had nearly no ice at all.

I assume it is not gas, as otherwise the freezer would not be working either? But I may be wrong.

Any other solutions would be very welcome. Thanks!
