Anyone familiar with wood stove blowers?
The fans on my wood stove I wouldn't necessarily classify as 'a blower' they look a lot more like a computer fan. Anyway, one of them barely spins, like it's hung up or needs cleaned out... well i pulled it all apart, it appears to be some sort of electromagnetic fan, i cleaned them out, blew them out with air, greased the parts where bushings ride, and it still didn't do much. Another one squeals like i'm roasting a live pig in the stove, but the third seems to work just fine.
I'm not sure if I can get replacements for these. I don't know the model number of my woodstove, only that it is an Earthstove.
The information on the fans is :
Aerovox S10625082
115V .5A. 60HZ
Impedance protected
Edit : I believe the fan blades to be 4.5" in diameter
Is there any way to replace these? I've done a google search and found nothing. If not, can i easily put something else into it as long as it fits behind the shroud? I'm just not sure about the fan control, maybe i'd have to replace that too? If nothing else point me in the right direction?
Thanks,

Alan
