Hi. We have a Samsung RSH7UNBP side by side fridge freezer which has suddenly stopped functioning. It still powers on and the display shows an accurate temperature of both the fridge and freezer (currently 14 degrees and 5 degrees respectively) but it appears to do nothing despite the freezer currently being set to -22 and the fridge to 3. The power freeze does nothing. This close to Christmas we're looking for a reasonable repair price, or even to find out if it's worth repairing.
