I have a Hotpoint fridge/freezer ff93 which is about 3 years old.
Unfortunately the top fridge section has stopped working and currently
has a temperature of 18 deg C but the freezer is still working fine.
There is a small vent at the top of the fridge section which normally
has cold air coming out of it but now has nothing coming out of it.
I have removed the cover at the back of the inside of the freezer
section and the cooling fan is working. I have also checked the
compressor fan on the bottom of the unit.
The other end of the vent is in the freezer compartment - I have
tried forcing air through it with a hair dryer suspecting that it
might be blocked but no air comes out of the other end. Is there a
valve of some description in the pipe which could be stuck?
I am unable to get into the rear of the unit as it is a "flat back"
model. Does anyone have any ideas how to progress this?
