If the problem with your GE gas dryer is that is not starting in any of the cycles that you are trying it on. You will need to check the following parts until you find out which parts is the one that needs to be replaced to get the dryer working properly again.
I am going to give you a small explanation below of the parts that you need to check but watching the videos is how you are going to learn how the repairs are done.
How to take the dryer apart: The most important thing you need to learn is how to take the dryer apart and how to put it back together again properly. Once you know that, everything else becomes very easy to do.
HI limit thermostat right: This thermostat is like a thermal fuse that is connected in series with the motor circuit. If the dryer airflow is obstructed, the dryer will overheat blowing the hi limit thermostat and stopping the motor from running. My video will show you how to check and replace this thermostat.
Idler spring switch: This is a safety switch that is connected in series with the motor circuit. It is activated or turn on when the belt is in place around the drum, idler pulley and the motor. It is used to stop the motor from running if the belt breaks off.
If you set the timer on a drying cycle and push on the start button and the dryer runs as long as you are pushing on the start button. But when you let go of the start button the motor stops running, you need to check the belt to see if it is broken or the idler spring switch to see if it is bad.
The start switch: This switch is only used to start the motor in the dryer. Once the motor starts running this witch is out of the motor circuit. If this switch is bad the motor is not going to start and the dryer is dead.
Door switch: This is another safety switch that is connected in series with the motor circuit. It is used to stop the motor from running if the door on the dryer is open while you are using the dryer. If you open the dryer door while the dryer is drying a load of clothes, the motor should stop running.
There 2 ways that this switch gets bad. If the dryer runs with the door open, the contacts are welded together and if a kid or a pet get inside of the dryer drum they could get hurt. And the other way is if the contacts inside of the switch fails to close when the door is closed. If you have either of these problems then you need to replace the switch.
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 starting.
Any one of the mentioned parts could be the cause why your GE electric dryer is not starting.
