Dryer stopped operating (no drum rotation). Door switch was faulty (no power on the circuit that sends current to the dryer's functional parts).

I replaced the faulty door switch. Now have high voltage at the motor (as determined with a voltage detector) but dryer still does not operate. Start switch is functioning OK. Lighted controls on panel are functioning OK.

Other than a bad motor, what else could be the problem? Could a short somewhere have caused the door switch to become fried?

Is there something I can check with a voltage detector and/or volt meter?

Note that I am too puny (seriously) to remove the motor.

Thanks

If you're getting 120vac (nominal) to the motor at the correct windings but the motor no workee, then i think you're dealing with an open neutral somewhars either inside the dryer or at the dryer's power supply. If it were a gas dryer, checking the outlet for an open neutral would be as easy as plugging in a lamp. Not so straightforward in a 240vac circuit like on your dryer but it can still be done with a little understanding of the dryer power strip anatomy and using a lamp with alligator clip attachments.
