Replacing cooker hood extractor

Completelylosty

So I need to replace my broken cooker hood. Silly question, but what things do I need to consider? 

I assume if the cooker hood (tube?) going into the ceiling is a smaller size, I would have a gap to fill in, and if it’s bigger, I would need to increase the size of the hole going into the ceiling? The vent goes under the floor boards in the room above. 

Would I be better going smaller or larger in size? I will get someone in to do the job, but I would like some advice before buying the replacement. I also need to buy replacement cabinet panels for the top don’t I? 

Thanks in advance

I think you got this...

Does the stainless steel chimney go through the ceiling or is it just the 150mm vent pipe that does? The chimney might just sit touching ceiling.

You could try to re-use the chimney section (might be different colour) or try to find a new hood with same size chimney?

If not the same size you need to cut a bigger hole (much easier) or fill in ceiling hole and get new panel. Otherwise chooser a hood that will hide the issues or negate need for panel. Could ask joiner or kitchen supplier for ideas. Might end up with a gap between splashback and new hood?

Is the current hood fixable? It's really just a motor in a box....

Most of this is a question of aesthetics rather than technical need (though a partner may demand a certain level of finish even if you'd be happy living with something ugly but functional). Much of the hood is just for decorative purposes, especially in externally vented extractors. 

You'll just need to know the width of the hood, the size of the chimney width/depth and the range of its length - most are telescopic. Some people might be picky and want the seem of the telescope to be hidden by the board going across so more measurements are needed, most dont have such a board so the seem will be visible. You wouldn't need to fill in the gap if the new chimney is smaller from a functional point of view but you may want to for aesthetics. Certainly thats going to be harder than being able to keep it the same size or enlarging it.

Rangemaster are a pretty well known make - Have you checked to see if parts can be replaced ?

If the hood isn't working, then it is likely to be a switch or motor at fault, both fairly easy to replace. Also worth checking the fuse (should be in a switch close by) before spending money on spares or a replacement.

Ahhh, now I think about it, I do believe the chimney does just sit on the ceiling. So that means it doesn’t matter what size my new chimney is, I only need to modify the cabinet panels.

The lights are working, so I guess it’s not a switch or fuse fault, but a motor fault?

With the right equipment, checking the motor isn't too difficult - Might be worth calling an appliance repair man to take a look if you don't have the tools.

I see the cheapest Rangemaster hood is £300 or so, and a spare motor could be had for as little as £40 - Repairing would be cheaper than buying a new one.
