We got an SOS from Liam – our head of IT – today. ”You gotta help me, the ice-cream in my freezer is thawing out”. His flatmate greeted us at the door. Serious business hands on hips ”Fix it or you’re toast!” Pressure on.
We duly inspected the appliance patient to find the freezer in question was an under-counter fridge with an ice-box type freezer.
This style of freezer has a * one star rating designed to store frozen food for up to 3/4 days.

* One star (-6 degrees centigrade) is perfect for making ice cubes and is sufficiently cold to keep food for three or four days.
** Two stars (-12 degrees centigrade) stores food for 15/20 days.
*** Three stars (-18 degrees centigrade) will keep food safe for up to 3 months.
**** Four stars (below 18 degrees centigrade) means that the compartment provides the ideal conditions for freezing down fresh and pre-cooked foods(also known as blast freezing.
