I think I have an idea what I need to do from searching the group, but this is what I have.
GE Hotpoint Gas Dryer - Model DLL2450R (About 13 years old)
Threw in a shirt this morning (didn't feel like ironing). Took out about 20 minutes later and it was slightly warm, but not hot like it should be for still being in the middle of the cycle.
I've had a couple previous loads this week not dry at all. Thought I was just going insane and forgot to start the dryer. After those loads I reset the cycle and watched the ignitor glow and flame light normally. Loads sat overnight before I found them, so something may have had time to reset itself and then lit properly. This morning the ignitor would not glow while I watched.
I've also had several loads over the last couple months not dry completly.
I'll clean all of the lint, check the exahust, etc when I get home. If thats not it, gas valve coils my most likely issue?
