Not technically a cooking disaster but potentially a huge waste of food - What can you do if your freezer fails?Don't Panic!
Keep the door/lid of the freezer shut.
Check that it is switched on at the mains.
Replace the fuse.
Check with friends and neighbours to see if they can store your frozen food.
Call an engineer - if the engineer is likely to be prompt keep the freezer door closed.
