It probably receives data from a device measure temperature and then could output instructions to cool down or grill up the fridge.
Don't know about the others but whenever a task have to be performed depending on certain inputs a MPU could be used.
It's a bit resembling a little brain. It just sits near until it receives a signal and then perform certain related actions. Your brain deeply waits for your senses etc. to give it some input, next it instructs your muscles whatever to react.
Most traditional electronic apparatus relied on an worker to press the right buttons or to start a pre-program. Newer machines sort of "think" for themselves. A washing machine could "sense" how much wash had been put surrounded by and then adjust the amount of water/soap powder/ time etc.
They all process opcodes as specified contained by their instruction set. :B
