Gas Dryer Starts to Heat then Stops

My Maytag gas dryer ignites a gas flame when first turned on, but the flame goes out after about a minute. The glow plug then comes on about every minute for a few seconds, but the gas doesn’t reignite. I’ve checked to be sure the vents are clear.

Many thanks for your help!

You either have a weak igniter, or need to replace the coils.
