Clothes dryers are wired with 2 voltages, The 240 volt supply is for the heating element only, while the 120 volt supply gives power to the timer and motor that spins the drum and powers any lights and switches. If the heating element is coming on, try replacing the thermostat. As always unplug the dryer first.
