Free range microwave (Longwood)

Free Whirlpool range microwave It's around 3 years old and it works, but it's gotten weaker somehow - it takes longer to microwave stuff.
So I replaced it with a new one of the same model.
I was going to recycle it but it still works OK.
And it includes everything: the wall hook, the plate, the plate wheel thing, the screws, etc.
The box and some accessories are from my new microwave.
