I have a Hotpoint Dryer (model # nbxr333eg5ww) and if I
press the start button it will not spin but if I spin it by hand
it will spin the set cycle. What could be the problem?
Here is the closest I could find on your model number.

If the drum turns fairly easily by hand then odds are that your motor is on itโs last legs.
You may want to try turning drums on a couple othetr units just to get a feel for it.
If the drum is hard to turn the at the top of the list would be the rear support bearing or the front glides.
