This looks like a 3 wire power cord. You need to unplug the dryer and open
up the back where the wire goes in. Look and there will be 3 terminals the
power wire hooks to. It will probably be the middle wire that is the
neutral and there should be a strap going from there to the frame of the
dryer.

While the dryer is open look around for any black or burnt areas near wires
or the internal electrical parts.



Three wire cord doesn't have a neutral.
Two hots and a ground.

Wrong! Two hots and a grounded conductor (neutral/white). These types of
plugs are often referred as a 120/240. Meaning that it provides both voltages
to the device. The new 4-wire plugs do the same thing, but have a dedicated
grounding conductor for fault purposes.

As per code, a grounding conductor shall "never" carry any current unless
a fault is present; and the only purpose for carrying this current is to
trip the breaker. The other purpose of a grounding conductor is to equalize
the potential of attached devices to ground, thereby reducing, but not eliminating,
the risk of shock.

(it is possible that the service is 110/220)
