GE Harmony gas dryer intermittently heats/doesn't heat

I have a GE Harmony DPGT750GC1WW gas dryer. Over the last few months, it would intermittently not heat up. Now, this occurs more often than not. I took off the front panel and turned it on. After running for a few minutes, nothing happened. I turned it off and then back on a few minutes later. The ignitor coil turned bright orange and the gas lit up. The gas then turned off about 20 seconds later. The dryer kept running. A couple of minutes later the ignitor started to glow in the center for a few seconds but then became "cool" again without any gas lighting. I let it run for a couple more minutes, nothing happened.

I don't know if I need to replace the ignitor or the gas valve. Is there a way to test these two parts prior to replacing them (especially since they are each well over $100). Thanks

If the ignitor glows then most likely it is okay. If the ignitor glows and then goes out without a flame most likely the valve is at fault.

If the ignitor only glows a couple of times and then stops glowing it may be a relay failure on the control board.

Intermittent problems can be difficult to pin down but if the ignitor glows but there is no flame then most likely the valve has failed.

There are no separate coils for the valve so the coils and valve are replaced together.

You say after the ignitor glowed for few secounds but stopped. You then let it run a couple of minutes more without an ignitor glow. Give it a few more minutes. The key is the ignitor glowing.
