You can't run a typical 240V dryer off a 120V

so actually if you incorrectly connect a 240 dryer to 120, it might turn but have NO heat

but if you knew what you were doing and hooked it up correctly it would spin AND heat but at 1/4 the power...

that might still be usable in a pinch

You're right, and you probably would get a little bit more than 1/4
the heat because the resistance
heating element would be running at a lower temperature and would have a
lower resistance. Like you say, might be usable in an emergency
and if you knew what you were doing. Another
factor is a lot of dryers today have electronic controls and exactly
how that stuff is wired, ie does it still use 120V for the control portion
or does it use 240V, IDK. Some even have fancy ECM motors now I think.
