on the main controller board there should be some micro switches these a relay type and were out or get overheated, but if this is on gas. it can be the flame sensor https://youtu.be/VTnDslKW6y0 electric.
I have Design a new solution it is the Dwadder.
Dwadder made from HDPE plastic. The Dwadder is the first ever Dryer Device that does dry your sheets and blankets faster! The Dwadder keeps your sheets and blankets from wadding up in the dryer. This will save you Time and Money when drying. Dwadder can cut your drying time up to 30 mins or more. Two sheets or blankets can be strapped to the Dwadder at a time to keep from wadding up in the dryer.
One of the most time-consuming uses of a dryer is drying blankets and sheets. The reason it takes so long is the blanket or sheet can be twisted into a tight wad or ball during the drying cycle. Once this happens the dryer is incapable of drying the center of the wadded blanket or sheet. The solution today is to take the blanket or sheet out of the dryer halfway through the drying cycle and unwad the bundle of sheets or blankets. Then place the blanket or sheet back into the dryer to restart the dryer cycle over and over again until the blanket or sheet is dried. If you forget to unwad the blanket or sheet when you get ready to make the bed, the blanket and or the sheet will be wet.In order to fix this problem, the Dwadder is strapped to the sheet or blanket using a silicone cord before it is placed in the dryer. Once the dryer is started the blanket or sheet will wrap around the Dwadder allowing a space to be in the center of the blanket or sheet. With the space that is created by the Dwadder the center of your blanket and sheet will dry faster and will not roll into a tight ball or cylinder shape. This will help save time drying your sheets and blankets. The device will also prevent wadding of your sheets and blankets so you don't have to unwad your blankets and sheets half way between the drying cycles.
How to Use the Dwadder
Simply pull half of your blanket or sheet out of the washer. Then pull the silicone cord to slide the blanket or sheet between the silicone cord and the Dwadder. Slide the Dwadder to the center of the sheet or blanket then put your blanket or sheet in the dryer with the Dwadder attach to your blanket or sheet. You can use both silicone cords for two small blankets or sheets just don't place 2 blankets or sheet on top of each other or it will take longer to dry.

It's possible if it was plugged you could have burnt something out. You don't state whether it's an electric or gas dryer. i say to get a professional person to check it out. That may be cheaper in the long run.
