Can anyone help me with how I can find a new oven hood that slots into the space where the old one is. We are making over our very dated kitchen with new doors/ workshops etc. We currently have an oven hood fan that hasn't been used since we moved in as it didn't work but we want to replace it now. It seems to be sitting vertically on the wall (photo attached) and is covered by a door, which you would open when in use. No idea how to find something new for this space as none of the fans I have seen seem to sit the same way? Googling the name on it, it seems to be a Whirlpool one but not sold now and can't see similar.
