DH and I recently bought a house with a very dated kitchen. There's an odd box on the wall wired to a vent of sorts and the box started leaking today. There's no water coming from the ceiling, just from the box itself.
Please help! What is this weird box for and why is it leaking? Where could the water possibly be coming from?
I've attached a picture - it's the box on the righthand side of the picture.
