Fan will not work

Question

Can anyone help me with the above.The fan only has approx 167v on its input and makes an effort to run.If I connect it direct to the main it runs OK.You can hear the relay operate when you turn the fan control k**b.I suspect the fan is controlled by the Electronic Control board but would like someone with more expertise to confirm.If it is the board, where can I get a replacement.Would appreciate any help.Many thanksDavid
