If you have the correct voltage 240 volts from L1 to L2 and 120 volts from L1 to Neutral and L2 to Neutral then odds are high that one of the thermal fuses has blown. Item 11 in the Heater section and Item 10 in the Motor section.

Best to unplug the unit and check them with a meter.

If you do not own a meter, I would suggest you purchase a one. You can get a decent digital multimeter for under $20.00. You do not need fancy though it is nice if the leads are a couple feet long.
If it saves ordering one unnecessary part it has paid for itself and you end up owning a useful tool.
Most places will not let you return electrical parts so if you order it, you own it.
A couple things to watch when measuring ohms and continuity
1. Always remove power from the machine otherwise you could blow your meter.
2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path.
3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale's dynamic range.

There is a good STICKY at the start of this forum about it's use.

If a thermal fuse is blown be sure to give the interior a good cleaning including the blower wheel. Also clean and check your vent system.
