Could be the control board or the centrifugal switch on the motor.

But the first thing to check is the power.
The board, motor and drum light all use half the line (120 volts) but the heater coil requires the full 240 volts.

Try flipping the breaker off/on slowly, sometimes you can loose half the line without actually tripping the breaker.
If this does nothing, check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
