You may want to check if there is 240 VAC at the wall outlet.

Here is the wiring diagram
http://www.servicematters.com/d...0Sheet%20-%203401728.pdf

Try flipping the breaker off/on slowly a couple times, sometimes you can loose half the line without actually tripping the breaker and the heating coil requires the full 240 volts.
If this does nothing then as Gene said, check the power at the plug
L1 to L2 should be 240 volts AC.
L1 to Neutral and L2 to Neutral, both should be 120 volts AC.
If OK
Unplug the unit and check that the wires at the terminal strip are good.
If OK
Check that the power is correct at the terminal strip. It is not unheard of for a wire in the line cord to burn out.
Be very careful when doing this as 240 volts is lethal.
If OK
Check that the operating thermostat contacts are closed.
If OK
Unplug the unit, set the unit to timed dry mid cycle and check that timer switch 2 is closed (0 ohms).
If OK all that is left is a broken wire or a bad centrifugal switch on the motor.
You can double check this by attaching one meter lead to L1, leaving it there and working your way back through the components of the heating circuit.

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.
