I have a 10 year heil gas pack unit when I turned it on today nothing came on.so I turned my t-stat to on to see if my motor comes on it did not does that mean my blower motor is bad

Not until you check other things it could be? Have you checked to make sure you have power getting to the unit.

If you are getting power it could be a bad transformer.

And it could be other things but these two are the most likely.
