DWJR-NAT-1206006. Why is the dryer not heating internally?

There should be an ignitor in the unit but I need to know the exact model number

Could be the element or any of the fuses.

This could be a few things. The first thing to check is your dryers vent, make sure its not clogged and check were it exits the house because sometimes nest are made in them. A clogged vent will prevent proper drying because the moisture can not escape and/or the heating element turns off due to overheating.
If the vent is clear, with dryer empty open the door and hold down the door switch (button that tells dryer door is closed) and turn on dryer, as its running watch the back area of drum were the vent with little holes is, within a few seconds you should start to see an orange glow in that area. If the orange glow starts then disappears within a few seconds it means your vent is clogged, if there is no orange glow at all then you have either a bad heating coil or bad high limit switches. I believe youtube has great how to videos on how to replace them, its not that hard if you have basic repair skills. Hope this helps you and your able to get it drying agian

There are multiple thermal fuses and also a thermostat and last is the heating coil itself.

Sounds like the vent has a lint build up inside of it. A moister sensor detects any lint build up and keeps the heat in check. The dryer will produce very little heat this was. Clean the entire venting tubing and it shall run better for you

Check the entire exhaust venting sytsem. If lint is inside of the tubing it will cause a restriction shutting the burner off at all times. If the tubing is clear the moister sensor is at fault and needs to be replaced

thermostat or a solinoid

try heater or themostats
