Can you tell me if the fan in the freezer is operating?
Check the compressor at the rear.. is it hot?
It is likely that the appliance is short on refrigerant... You'll need to get a refrigeration engineer to call and recharge the system but at the same time seal the system using 'Super Seal'.
This needs to be done before the refrigerant depletes further, else the compressor will then run too hot and possibly then become damaged
Yes, but if the refrigerant is low then it does not reach the full system and the compressor then has to work overtime, hence the reason it gets hot.
