I have had the same problem. Following the advice of someone on these pages I opened the machine up and checked the fan with a meter. On my model (the 404) it has two settings so two leads; one seemed okay, the other was dead. I checked the circuit where the fan connector plugs in and I got that both speed settings were supplying plenty of juice. Apparently the fan motor is dead. A replacement runs $79 at http://www.appliancefactoryparts.com/. I ordered one; we'll see what happens.
