More than likely the board is bad on the board. Can you get at it to check the board and inspect it for a burn out?

No sign of burn out, how can I check the fan motor, by bypassing the board

Get at the board on the motor and look at it to see, check out this link to see what I mean.

Can I check voltage to fan motor to make sure the motor is good

That is the board for the unit, that unit uses an ECM blower motor there should be a board motor on the blower as well. You really can not test for power to it as it will tell you nothing on that unit.
