I have a Jamestown J1000 that came with some pipe I bought, have been trying to figure out why it goes off on high temp, notice convection blower was not really putting out much air. Open the stove and watched fan, it looked like it was going in reverse. Took out blower spun the way it was going no air, spun in reverse air flowing good? Can I reverse the white and black wire to make it go this way?? Any suggestions?
