The big freeze

Three weeks ago, the fridge/freezer in the kitchen went into overdrive, plunging the fridge compartment well sub-zero. A hasty defrosting of the freezer seemed to fix it. Until today, when I came to get breakfast, and found that it had happened again! So the freezer contents go out into the backup freezer in the garage, and I wait for the thaw.

Why can't it wait until we have a date for getting the kitchen refitted?
