The first thing you have to do is get a schematic. Once you find the schematic
and are able to find the FAN you MAY find the entire problem. It is probably a
power supply problem. But, you need to know what supplies are generated and
where. Once you know that you are in business. Also, check very carefully for
any more fuses. Sometimes they are very cleverly hidden.ince the fan does not
run it may be just a matter of finding the powerr supply that suplies the fan.
There may even be a sticker on the fan which will tell you what voltage it is.
Then search out that power supply.
