I noticed a 3.15A fuse was blown, I tried replacing the fuse with a new one, but it just blew out right away as soon as i turned it on. Is it the fan that's causing the fuse to blow?
 
Probably not the fan.

If the fan failed then the temperature will be high and something will fail. That something will pop the fuse.

Why does it display "protection fan"?
 
I really don't know but maybe the fan failed and that is the last error it received.

Well I stick my finger in the fan. If I pull back a bloody stump then the fan is running very well.
lol
Don't you wish I was even a little helpful.

If you are popping fuses then you have bad power transistors. most likely.[/QUOTE]
This is better than no help at all. So the fan isn't working because of the blown fuse caused by the bad transistor?
 
Generaly its not a good start if you don't know where to start. A circuit diagram of the unit would be a good start?? And maybe pictures of the insides of the unit. Does it actualy have a fan in it??
