I am assuming that by correct power, you have checked for 240 volts at the terminal strip in the unit.
Another test is to check that the timer advances in timed dry when the unit is running. It also uses 240 volts.

Note that the thermal fuse on the blower kills power to the motor.

Using voltage when trouble shooting heating problems can get confusing because Neutral/ground is not part of the heater circuit.

You are better off starting with resistance.
It is a good idea to disconnect one side of any device you are measuring as this ensures that you do not read an alternate/parallel circuit path.
Also in the heater circuit you should use your most sensitive meter scale.

The heaters are usually in the 8 to 12 ohm range.
The hi-limit, thermal cutoff and the operating thermostat should all be 0 ohms at room temperature.
The timer switch 2 should also be 0 ohms when the timer is in a hwating type cycle.
