samsung f/freezer spares/repairs (Collier row romford. RM5)

Large Samsung RS21NCNS side by side fridge freezer in excellent condition but not getting cold
It has power, lights and fans come on but does not cool. It is in a pristine condition, all shelves and drawers are present, intact and undamaged. It has a brushed silver exterior finish. 26” deep x 35.5” wide x 68” Tall. Free to collect. I just don’t want to send it to landfill if I can help it.
Please do not apply if you’re not serious about collecting. Many thanks.
