In '08 Bioheat (Tarm) shipped their Innova models with 50 cycle fan motors, and promised to replace the motor when the 60s became available. Well it's been a year! Now they are sending me a capacitor that they say will convert the motor from 50 to 60. I don't trust them because when my unit came, they tried to pass off the 50 cycle as being a 60, but I read the nameplate which said 50. I doubt that a capacitor will make the conversion. Can anyone give me a definite answer on this? Thanks.
