i have an old shenandoah fpi insert...has 2 blowers...they are c motors..like bathroom vent fans....i replaced one last year and one this year....what a pain..couldnt even find the right one this year..had to do some engineering to make it work...and its still not perfect...also my rhestat switch is going bad(turns fan up and down in speed)....i wanna do away with the rheostat....i always run my blowers full blast.....can i just put in a toggle switch in place of this?
