I've had one of these since the '90s. Depending on amount of use, it will eventually get clogged with dust and gunk. Then it doesn't want to start.
Every couple years I have to take it apart and clean the blade shaft, lubricate the thing and reassemble. Be very observant how the parts (wires, capacitor etc) are attached so you remember how they go back together.
Judging by some other questions here, this is a typical problem with this fan. If it's overheating, you may have another issue involved.
