Neff model no K8524X4GB/02. Integrated.
This fridge freezer stopped cooling with no signs of life other than the temperature light flashing and the interior light working.
After leaving overnight (switched off) it started up normally and ran perfectly for around 24 hours, only to revert to the previous state.
It is 10 years old, but is in very good condition.
I have contacted Neff and have two options: engineer visits (£95 plus parts) OR pay £15 per month for 12 months and have the engineer fix the problem (providing it is no more than £300).
Any armchair diagnostics/advice welcome.
