It turns out that a microwave can be easily fixed. The symptoms are luke-warm food.
Here from the image above you can see the cracks in the magnets. These develop because the heating and cooling of them over time fatigue the fragile compound they are made from. I therefore, bought a new Magnetron (love that word) and plugged it in. It has now been working for over a year without issue.
The specification of the quad are as follows.
