If the problem with your GE gas dryer is that is heating but is not heating properly. In other words the dryer is getting too hot or not getting hot enough, you will need to check the following parts until you find out what is the cause of not heating properly.
Gas valve coils: These coils are on top of the gas valve and are used to open and close the gas valve as needed. If one of the coils fails, the gas valve will not open to released the gas.
The gas valve: The gas valve is used to control the pressure of the gas entering the dryer. It has a regulator to control the pressure of the gas coming from the main gas line from the gas supplier.
The motor: The motor is the work horse of the dryer. It is use to turn the tumbler and to complete the heating element circuit. A bad motor could be the cause of a not starting Ge electric dryer.
The timer: The timer is the brains of the dryer. All the contacts inside of the timer are use to direct electricity to all the different electrical parts inside of the dryer. With time and amount of usage of the dryer, the contact inside of the timer wear out or burn causing the timer not to work they way that is design for and could be the cause why the dryer is not heating.
The temperature switch: This switch is used to select the temperature that you want to use to dry the clothes. A bad switch could be the cause of the dryer not heating.
The thermostats: The thermostats are use to control the amount of heat inside of the drum to dry the clothes. They are connected in series with the heating elements circuit. If a thermostat is open when it supposed to be closed, the dryer will not produce heat.
The motor centrifugal switch: This is a switch that completes the circuit to the heating element only when the motor is running. If this switch doesn't close when the motor is running, the dryer will not heat at all.
