My dryer will not dry the clothes. I put a load in Friday night and when I got up Saturday it was still running and the clothes were still damp. The timer never moved. I replaced the timer and its still not drying. I watched the flame come on for about 97 seconds and stay on for about 1 minute then go out. It would come back on but only for 30 seconds. Then go out and not come back on. The glow bar would continue to go on and off but not light. What part should I change next? Thanks for your help.

Check the coils on the gas valve

It was close . Turned out to be the solenoids . Thanks for your help
