Dryer heat turns off after about 5 mins. and does not come back on

Kenmore Dryer, Model 110.70802990.
Flame goes out after about 5 Mins. running, and does not come back on. I opened the front cabinet and checked the Radiant Sensor with multimeter and it has continuity. Replaced both the Thermostat and the Thermostat Internal Bias. After the flame shuts off sometimes you can stop the dryer and restart and it will get hot again then flame goes out and does not restart, gets completely cold. Sometimes you have too wait for the dryer to cool off then restart and it will heat up again, Then flame goes off and does not refire after cooling down.
Help!

Your symptoms point to weak gas valve coils in that dryer. When the dryer starts from a cold condition, the coils are strong enough to open the gas valves to ignite the burner. Once the dryer runs for a while and those coils heat up, it sounds like they are too weak to open the gas valves for ignition of the burner. I recommend that you replace those valve coils in your dryer. There is a kit that has both coils for about $20. That kit is part number 279834. Here is a direct link for that kit:

. Here is a link for a previous answer that shows how to replace those coils:

This information should help you fix that dryer heating problem. If you need more assistance, reply with additional details.

If you get to the point where you need to have a service technician diagnose and repair this failure, you can schedule service through this link:
