Brand new kitchen extractor hood fitted last week. The lights still work, but the fan won’t turn on, so I assume not a fuse problem.
The extractor duct was about 5mm too large to fit in the top of the hood, so I squeezed it in best I could and used duct tape to seal it; might this cause an issue? Or is it just a dud? (Cheapest hood from screwfix, had good reviews).1
