Though somewhat crude, I used an old school (non intelligent) battery
charger to test my fan.

That resistor gets hot with fan on lower speeds. I'm sure the specs
are buried somewhere in the archives, but you should be able to put a
VOM on the resistor and measure the resistance. IIRC, it is used only
for the lower 2 speeds. Highest setting voltage passes straight to fan
bypassing the resistor.

My guess is that if the fan stopped spinning (it's death) then parts
in it started to smolder. Did the fuse blow when motor died?

Now I have a new fan motor too but I do not see anything burnt in the heater box. Is it possible it was that resister in there? It looks fine. �Is there a way to test this fan before putting it all back in today?
