Have had the fridge checked and coolant pipework is blocked so buying new fridge. Currys [after my complaint ]eventually offered some cash [its nearly five years old] so I mentioned the freezer door handle was broken and they doubled offer so have around £150 towards replacement fridge and can replace freezer handle from the broken down fridge.
