Ok Jill thanks,
First thing to do is go to the breaker panel and shut the fuse off all the way then turn it back on, If this fails to clear the problem then it is very likely the thermal fuse has blown, In this case it is mounted on the heater housing, Pull the wires off then test it with a ohm meter, If it reads open you have found your problem :)
If you don't feel comfortable doing the repair yourself then a repair guy would charge around $120 depending on region to complete the repair.
