Yesterday (while I was out) my OH noticed that the external thermometer on our freezer was registering a much higher temperature than normal - it is fixed to the outside of the freezer with a wire and probe that go into the cabinet. I opened it and saw that all the relevant lights were on and the food felt frozen but the dial was at the highest level - it turned out OH had set it there following a bit of "tinkering" (his speciality!.
The temp has remained high, even after me resetting the freezer dial and putting it on temporary fast freeze. I have removed the thermometer and tested it next to the outside thermometer, and also in the fridge; and what it is registering makes sense - so I am guessing that the thermometer is not faulty.
However the freezer seems otherwise fine and its alarm has not beeped; which it should have done if the temp inside went dangerously high.
The thermometer has continued to register higher than normal (c.-14.5 to -11, rather than -21) - but no sign of thawing of food.
I don't know quite what to do!
Jersey trip, some tips please.
