Always take a look first... to see if you see anything wrong with it..
I'll talk about a gas dryer.. sorry but i dont have an electric one..
First, let's try to understand how this works.. in most of the cases.. is almost the same.. so..
when you choose a cycle and then select the time.. the dryer starts to run, that means.. the motor starts to rotate and moves the belt around the cylinder .. at the same time the timer starts to run and tells to gas valve (70) to release the gas (through 2 coils-71 & 72) so the igniter (74) will spark and get the flame out.. the flame sensor (79) will control the size of the flame and then the coils will shut down.. and this is basically the process.. there are some other parts i didnt mention.. but I just wanna focus on the problem here..

Image taken from partselect.comOk. so if your dryer is not heating up, there could be many reasons for this problem:
1. The igniter is burned.. this happens a lot since it's a delicate piece.. try to look for the model of your dryer to locate where this igniter is.. usually is next to gas valve
2. the flame sensor is not working.. but if you run the dryer and you dont see any flame at all.. then this is not your case.. if you do.. then you need to get a replacement..
3. the timer is not working.. if so.. that means that nothing is going to run as is supposed to.. so you need to replace it.. but i doubt this could be since it's rare to see a timer fail..
4. the gas valve is not releasing gas for the igniter to light up the flame.. to check this, run the dryer and see if the igniter is making a little flame, like a sparkle.. if so.. that means one of the coils is not working.. Usually you will see 2 coils.. one for the igniter and the other for the burner (77).. which gives the flame.. if this is your case.. then you need to replace both coils..
Hope this helps you.. you can find some parts online.. ebay if you want.. most of the parts are compatible..
Note: To get access to all the parts mentioned here.. you need to take apart the fron panel of your dryer.. most of dryers can't get opened from behind since the cylinder is mounted for its rotation.. so.. dont even try it.. check always your dryer's model and user's manual..
Cheers.
