Well, I stuck a temperature probe in my old chest freezer and discovered
that its not really performing to spec. Its a 3/4 star rated freezer (I
think he 4* rating only applies when the fast freeze mode is switched on)
and the temperature seems to cycle between -15.5 and -12 C.

When I turned it off for the hours the temperature rose to -4 C which is
clearly not good for longer term food storage. Fortunately its very much a
€œspare€� freezer thats only been pushed into service to allow us to
stockpile a few essentials should we have to self isolate.

Anyhow, I dont think that the insulation has obviously failed (the case
isnt bulging anywhere) but I was wondering if I could just glue some
kingspan/celotex etc to the outside? If I were to do this, should I glue
the foil side to the cabinet or have the foil to the outside?

Has it lost some refrigerant?

Im assuming youve checked it isnt frosted up? We had one which did this
if it needed defrosting?

Another option is air flow around the €˜radiator on the back. We had one in
a shed ( it was rated for use in out buildings) and it got a bit clogged
with dust, saw dust etc. A quick clean and it was back to normal.

Door / lid seals are another common fault.
