Fan not working, having had grease removed (3-3)

Ross

I believe the answer is:

non-fat

I'm a little stuck... Click here to teach me more about this clue!

'had grease removed' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'fan not working' is the wordplay.
'working' is an anagram indicator.
'fan'+'not'='fannot'
'fannot' is an anagram of 'NON-FAT'.

'having' is the link.

Can you help me to learn more?

(Another definition for non-fat that I've seen is " Low-calorie".)

I've seen this clue in The Telegraph.
