I've got a blower unit on my wood stove. The control box for fan speed has lost its variability. I can only have it on high speed otherwise it barely blows at any other speed. I've determined that its the rheostat. I've called a couple dealers and the genuine oem replacement offered by the manufacturer is over 150 dollars. Which is totally ridiculous. 

 

I dunno where i can source an exact replacement of the unit as i figured it has to just be some Chinese build unit. Is it possible to fix the existing one?

 

Antoine know a thing or two about these?

All you have to do is leave that switch on high, and wire a rotary dimmer switch into an electrical box that you splice into the power wire.

 

This is the switch I used on my old stove: http://www.homedepot.com/p/600-Watt-Rotary-On-Off-Dimmer-White-R50-06602-0IW/203878272
