Default Fridge/Freezer Auto-defrost failure

The manual says
Quote:
Freezer
The freezer compartment of this model is of the «frost-
free» type. This means that no frosting occurs on the
inner walls of the compartment or on food during
operation.
The absence of frosting is achieved by constant
circulation of cold air inside the compartment,
produced by an automatic fan blower.
Has the fan failed?

Question
our Zanussi Electrolux Frost Free ZNB3240 frost free frdge freezer - 5
years old - seems to have stopped being frost free. I had to manually
defrost the freezer bit, the fridge ices up at above setting 1. I no
longer hear the motor/fan which I think I used to hear to periodically
defrost the freezer.

Answer
Hello Chris, if the fan motor inside the freezer is no longer running,
this would create problems such as the freezing of the evaporator coil.
Because the coldness of the coil is not dissipated in the freezer. What
you can do is remove all drawers in the freezer and remove the inside
back wall of the freezer. This would exposed the fan in the freezer as
well as how frosted the evaporator coil is. Please tell me how frosted
the evaporator coil is. And if the fan is running or not.

Maybe the fan shaft is now rusty and doesn't rotate cleanly -
Lubricating the shaft as it goes through the bearings may free it.
