I have an Amana dryer on a 220V 3-prong receptacle. I was turning the
timer dial and suddenly there was a pop! and then nothing - there is
no power at the dryer - the light doesn't even come on. I checked the
fuse box and rthere were no tripped breakers, but just the same I went
ahead and flipped them all off and on. Still nothing.

In simple terms a 240 volt 3-wire circuit consists of two 120 volt
circuits with opposite polarity. The L-shaped contact is both the
neutral and ground. Measuring from there to each of the hot contacts
should show 120 volts, and there should be 240 volts between the hot
contacts.

The fuses or breakers for this outlet should somehow be ganged together.
If cartridge fuses are used, typically the fuseholder has two fuses.
Pull it out and check the fuses with an ohmmeter. Often, dryers are
protected with two plug fuses in a separate enclosure with a big on-off
lever on the outside.
