It is odd isn't it and that's why I never suspected the cause of the
failing fridge freezer. It nearly got thrown out because setting the
thermostat about half way would cause the condensor to stop after a day
or so and the entire contents of the freezer would defrost.

That's why I got some wireless fridge feezer thermometers to provide an
alarm when this happened. I would then put the stat to max and let
everything freeze down.

The interior bulb was blown in a way that on ocassion it would light up
and I wonder if that was a loose filament which intermittently improved
the circuit function.

Never mind, a new bulb cured everything and the fridge freezer now works
perfectly as well as being well illuminated!

I 'pushed the boat out' and spent about 4 quid on a pair of 1.8W ses
pygmy lamps a few months ago to replace the 15W tungsten bulbs in our
under counter fridge and the chest freezer[1]. It never occurred to me
that they could be used to compensate for extremely cold ambient
temperature operation. In both cases, there wasn't any sign of a 'Low
Ambient' switch to keep them lit for such a purpose so isn't a potential
problem that, in this case, won't arise since our kitchen never gets any
colder than 15 deg C anyway.

[1] I did it because I could and was curious as to whether it would offer
any improvement in lighting and reliability rather than because of the
minuscule savings to be made in electricity consumption.
