Lump of ice just slightly above the (flattened) V-shaped drainage

Why? Feck knows. Sorry.

If that happens, I guess the channel is blocked, so the water
which sits in it right under the evaporator is likely to freeze.
f you remove the ice, can you actually pour water into the
channel and have it run away? (only test with a small amount;-)

No, it's not directly above the hole, it's off to the left a bit and it
leaves the drain hole clear. The condensation from the back of the fridge
must run down and freeze at that point and after a few days enough ice
builds up to disrupt the flow of water down the channel.

I think Peter's right - the insulation must be dodgy at that point. I will
investigate. Later )

Hi,

I reckon when you close the door, as the air inside cools down to
temperature it sucks more air in through the drain hole. The moisture
in this air then condenses and freezes at the nearest cold surface
leaving the lump of ice.

This worsens in summer as the air has more humdity and the fridge is
used more. I've heard that extending the drain hose helps, I s'pose
that insulating it heavily would too, you want water to condense out
of air passing up the drain hose before it reaches the fridge.

Running a rechargable battery fan on the lump might thaw it as the air
in the fridge is above zero.

cheers,
Pete.
