I have an Iceland Kyoto KU106 Freezer.
It has three lights top right of the unit. The left orange has 'FF' next to it, the middle light is green (marked by a squiggle with a line through it) and out, and the right one is red and on. It is marked with a triangle.
The unit makes a gentle rumbling when switched on. It doesn't freeze. What is the most likely cause?

FF will be Fast Freeze
The green with squiggle will be mains indicator, which should be on, the red will be error. From what you say, could be the compressor has a fault. It is the only moving part, unless there is a fan inside. Listen for where the noise comes from, you should be able to determine if it is compressor.
