Check for mechanical binding or seized bearings. If you feel resistance or hear rasping or scraping sounds when you rotate the shaft by hand, the bearings may be worn or seized.

Can a motor run without a capacitor?

Answer: There are three common types of single-phase motors named capacitor motor, shaded pole motor and split phase motors. Shaded pole and split phase single-phase motors do not require a capacitor to run.

Can engine failure be fixed?

If you do have a blown engine, whether or not it can be fixed depends upon the extensiveness of the damage. If the damage is minimal, and a few parts can be replaced, the problem can be fixed. However, if the damage is great and impossible to repair, you may need a complete engine replacement.
