Our oven door has had a long standing problem, it doesn't shut properly. This means extra noise in the kitchen when the oven is on and heat leaking out. So I finally got around to trying to fix it. And rather remarkably, after lots of jiggling, disassembly and reassembly I fixed it. The door now shuts properly, if a little stiffly. The reduced noise is very noticeable. And all I needed was a screw-driver. Over 40? Pah!
