Most common problems with no heating would be the heating element or the hi limit thermal fuse.
Also, check you vent if the clothes are hot but not dry, at the end of the cycle.
You could also have a breaker that is tripped. You will have a double breaker for a 240v dryer. You only need 120v to run the drive motor, but 240v to run the heating element. THIS DOESN'T HAPPEN OFTEN, but it does happen. Turn breaker all the way to off and then back on.
