Bert,
All the sites I visited show a 10 amp fuse too. Things are a little more complex....someone snuck in a new motor and wiring!
The interesting thing is that your post indicates the motor will run on high for awhile before it pops the fuse. This sure is indicative of a undersized fuse that is merely taking its time to overload and pop.
Improper wiring would usually result in a instant short. What does the motor do on LOW, or if there is one, a medium speed. Is it only the high speed that kills the fuse?
There was mention of an incorrect fan assembly in one of the posts I searched. If the motor were run at HI, and couldn't move the air properly, it would tend to load the motor and make it draw more current.
If wire size was adequate, sticking a 15 amp fuse in would be a interesting experiment. If this fuse blew too, but after a longer period of time, you would definitely have to find the problem. If wire size was adequate for 15 amps, and this larger fuse solved the problem, you would have found your solution.
Could the replacement motor you installed have had a higher current draw than the stock motor, thereby neccesitating a larger fuse?
