A little plastic piece of our bathroom's fan heater broke. It looked easy enough to fix if I could figure out what company to call to get another one, but the heater is made under several different brand names, so it looked like one of those things that could easily turn into a wild goose chase.
Instead, a little Googling led me to the main company, and when I called them I got a very helpful customer service rep who promised to mail me a part in two days. The part arrived today, and in just a few minutes I was able to fix the heater!
