A cooker hood not extracting correctly is a very common compliant that people have with these appliances and there is a number of simple things that you can do yourself to prove or disprove that there is a fault with your extractor.
The first thing to realise is that cheap cooker hoods are, well... useless really. Seriously they are just rubbish, we used to joke that the cheap Italian hoods buzzed a bit, lit up and did nothing else. Sadly it still holds true in many cases.
