The fuse is supposed to blow at 30A x 12V = 360W. That much power should not be heating up a 110V lamp cord.
I am going to pull the blower motor and have a look. I need to find the thread for how to do it.

Current draw of the blower motor during normal operation would probably be closer to 200W. The fuse rating will be well above typical current draw. That being said, even 15 to 20 amps through lamp cord is a lot of current for the typical gauge wire found in that type of cord. Remember, even a 100w bulb in a table lamp will draw less than 1 amp of current.
The point of my blathering is that the cord being warm is not necessarily an accurate measure that the blower current draw is high.
