Modern appliances are designed with parts that fail easily and are just slightly too difficult, or dangerous, enough to repair on your own. Usually it's a plastic connector of some sort that will have an easily calculable time-to-disintegration measured in years.

For instance, I just fixed a 2c plastic clip that pretty much made my microwave unusable by virtue of the door being un-openable. In order to do so, I had to have my fingers about 3 inches away from a bare wire transformer which near totally obstructs what should be a very simple fix.

Plenty scary and dangerous enough for me to have to call the manufacturer and find a certified local repairer...
