The timer: The time is the distribution center in the dryer. It closes contacts to direct electricity to the electrical parts in the dryer according to the selection on the timer. For example, it sends 120 ac volts to the motor and 240 ac volts to the drying unit. Check the video below to see how to check & replace the timer.
Temperature selector switch: The timer sends electricity to this switch and according to the selection on the switch the switch sends electricity the thermostats and the drying unit. This switch doesn't go bad too often, but it need to be check when the dryer is not producing any heat.
Cycling thermostat: This thermostat is used to control the air temperature inside of the tumbler. It is wired in series with the element. If the thermostat fails the dryer can't produce heat.
Hi-limit thermostat: This thermostat is a safety device used to open the element circuit if the cycling thermostat fails to open at the preset temperature. It doesn't go bad that often, but it need to be check when the dryer is not drying the clothes.
The motor centrifugal switch: This switch is inside of the motor and completes the circuit to produce heat when the motor is running and opens the circuit when the motor is not running. If this switch goes bad it is better to replace the complete motor.
