I've experienced this on several of my Cruisers. Seems to be a common ailment.The fan in the hj75 only had the two fast speeds working so pulled the resistor and the middle coil had overheated and broke. I had a good 60 series resistor so decided to rebuild the hj75 with the 60 coils. The coils are a lot thicker but It works well on all four speeds.
