Hope you all can help. My 70 series dryer heats up for a few minutes then turns off and cycles through this. Reading other related posts, I replaced the gas valve coils, but the problem remains. The igniter lights the gas, it stays on for a few minutes, then turns off for a few minutes, re-ignites, runs for a few min the repeats process. It seems each ignition cycle gets shorter in terms of how long it heats.

Appreciate any thoughts you might have. thanks

Thanks Simon. I put the dryer back together last night and will be running some loads through it in a day or so to verify. Problem before (replacing the coils) was that the first load pretty much dried, but didn't afterwards.

Thanks again and will let you know how it goes
