Hi David
I only came on here for a look and now I find myself embrioled in answering questions.
Frost Free are like women totally imbalanced and also illogical.
There could be a number of factors that petain.
Number 1 there is a kick plate at the bottom of the appliance that will need to be unscewed, it is possible it is blocked up by debry, which will need vaccuming out, this is because it reduces air flow.
If this does not show my recommendation you have an internal ice blockage. Ice is a poor conductor. From the lower department, the freezer air is sent to the above compartment, the fridge however if there is a ristriction in air flow it is usually due to an ice ball within the freezer.
My advice is take all products out of the appliance and keep safe within a friends freezer turn it off for 24hrs restart and hopefully all will be well. Should that not work you have a problem with the derfrost heater and you will need assistance.
Regards
Julian
