Deceased Swan Combination Microwave Oven (Blyth NE24)

My much-loved Swan microwave oven, model SM21070, has died. No display, no response to button presses, nothing. The fuse in the plug is OK so the cause of death must be internal. If you can repair it or use it for parts you're welcome to it. But please treat it respectfully as it had served me well all those years. Comes with the User Instructions so you can read how it used to work. It's heavy, and I can't help you lift it.
