I dont have that machine but my experiance with the boards has not been good I went through 5 of them Grizzly replaced everyone no questions asked but as soon as the warrenty ends and if I loose another board I will switch over to a board from a tread mill they are much more robust. I for one one almost bet it is the board several of mine just quit with no sign of damage on the board. On these sieg boards they dont use a FET or an SCR they use a Trench Semiconductor there a little differant but they do go bad these boards are not built very well.
If this is a brushless motor then the board is really differant you then have a ESC that basically turns the 120V into 3 phase square wave using PWM to control the motor a good substitute for this is built by Dart speed controls you will see them for sale on place's like Ebay fairly reasonable because they are not as common.

Here is one it is for low voltage but you will get the picture. http://www.ebay.com/itm/Dart-Contro...570?pt=LH_DefaultDomain_0&hash=item3f1de48e62
