The paper test is fine though I don't see why that would cause the
freezer outlet pipe to be full of ice (presumably).

I was thinking more about the general build up of excessive frost/ice in
the whole compartment caused by a faulty door seal. Much the same as you
would get if you left the door open for a few hours. The moisture in the
"new" air freezes.

Perhaps the freezer drain pipe is partially blocked with mould and
air-bourn debris/dust etc..

I can blow back up the pipe ok. There was an anti-siphon device in
the end of the pipe that I thought might cause a restriction so I
removed it.

When I next defrost I'll push something more robust up and see if that
clears anything. Meanwhile it is now at -20 and full of stuff again.
