Hi oz doc,
It's actually called just that, a "pencil dryer". It is fitted in the liquid line, which is a tube (probably 1/4") coming from the condenser. The pencil drier is tubular, copper and probably around 100mm long and near 20mm diameter. From the pencil dryer there is a capillary tube (probably around 1/8" diameter) which then goes to the evaporator (freezer coil).
Unfortunately, it's not a job that one can do yourself as you need the proper gear like high vacuum pump, gauges and of course, refrigerant gas. It's a licenced trade with heavy penalties (around $10k) if you get sprung - all to do with saving the ozone layer and global warming.
However, you may be able to diagnose if this is the problem. Run the fridge for say 10 or 15 minutes and feel the capillary tube where it leaves the pencil dryer - it should be warm. If it is cold, (sometimes even frost may be evident) then there is a partial blockage. If it's totally blocked, then this won't work - it will just be warm all over. Worth a try though.
Hope this helps mate.
Cheers
Gerry
