Ventilating fan broke down after less than 2 years ( 3 year warranty). Called Panasonic, expecting it to be replaced (as it was about $100, I didn't expect it to be repaired). I was told (get this) that I would have to hire an electrician to take the fan apart to determine which part is bad; then they would send me a replacement part and the electrician would have to install this part. When I pointed out that 1) electricians install ventilating fans, not repair them and 2) even if they did, the cost of the electrician would far exceed the cost of the fan. Response (not in so many words, but clearly in attitude): too bad. I might expect this from a fly-by-night company but not Panasonic. In addition, for a fan to break down in less than two years shows poor design or construction. And, by the way, the fan was installed in a guest bathroom and was very seldom used.
