I'm afraid I did not get it clear.
Does the igniter glows intermittently or it does glow every time but the flame goes on intermittently?

Thanks Gene and SublimeMasterJW,
Here is how to reproduce the issue.
Starting the dryer by press the start key, typically the heater can start at first time.
If I stop it after the fire is turned on by open the dryer door and then close the door, typically the ignitor will not be lighten up if I press the start button again, but dryer motor will start running.
Eventually the ignitor will be lighten up after a few cycles like open the door to stop the dryer - close the door - press start button again.
Once the ignitor lights up, flame will go on.
Thanks.

The igniter, as well as the flame, should cycle on and off depend on the temperature inside. It controls by the cycling thermostat which reads temperature inside the dryer. The actions you described do not show the real picture. You have to start the dryer and monitor the igniter and flame without manually interruptions of the cycle for at least 20 minutes.
Gene.

Gene,
Thanks for your reply.
I will keep monitoring it to see if that is really an issue. I agree with you, my operation described in my previous post is not a valid use case.
This forum is really a great help. If I found it earlier I think I would not throw away my 5 years old dishwasher. It is the first time I try to fix an appliance.
Have nice day.

On a regular cycle the gas is going to go on and off all through the drying process. It only takes a short while to get the drum hot. The gas does not stay on continuously. Nor does it stay on very long when it fires off.

I have a whirlpool gas dryer with same problem. The igniter will not ignite because no power is getting to it. I can only think that one of the 2 solenoids may control power to the igniter but I can not find an answer in the Forum or elsewhere.

On the blower housing is the control klixon. Next to it is a fuse. Bothe are wired together. If that klixon is cold and the dryer is set for heat then power will be applied to the gas valve assembly. Those coils, the flame sensor, and the ignitor are all wired together. Why won't the gas come out? The ignitor has to change in resistance to allow the coils to open the gas valve. To do so it must get hot. Then the flame sensor which really should be called the ignitor sensor opens and kills power to the ignitor. The gas comes out and hits the ignitor and lights. This causes the drum to warm up in a few moments. When the temp reaches 160f then the klixon opens and kills the power to the gas valve assembly. The dryer keeps a going. As the temp inside the drum is absorbed by the clothes and slowly drops, at around 105f the klixon closes contacts and fires off another blast of heat into the drum.
So the sensor and ignitor both should have continuity. if either is open then you ain't gonna have no heat. The fuse next to the klixon will melt and you won't have no heat. The dryer will still run if the fuse is blown. Their will however be no heat. If the klixon is good and the fuse is good, the flame sensor is good and the ignitor is good AND yall can get it to heat a little but quit then them coils need to be replaced. Coils getting hot and failing is a common prob on older gas dryers.
