hi do you have a segment flashing on the front display ? ..
if so you will need a new ice maker .. this is a known issue with samsung fridge freezer ... ie when ice maker goes faulty - the whole appliance can cut out ..
you will probally have the lights coming on but nothing else ..
check out this ebay item and the video also in the ebay listing ..
