The fan is switched by a thermistor located on a Fet board, I have replaced 
them w/ a used 1 in the field. Unfortunately the only way it comes from 
Xantrex is glued to the transistor, you can pull 1 from a bad fet board and 
replace it on the heat sink, or solder a new 1 from X. I have used, used 1s 
and they still seem to be working fine,You can do the repair (either repair 
in the feild) These problems seemed to be on the SW4024s around 
98-99.Contact me off line if you need additional info. TUMP
