The dryer stopped heating, ran the self test and Flow Sensor had full bars. I have cleaned every part of the dryer including the lint trap, exhaust pipe and even removed dryer covers and vacuumed inside. Still doesnt dry and still get the Flow Sensor bars when running the self test. I have removed the exhaust hose from dryer to make sure it's not an issue with house vent and still get the FLow Sensor at full bars. I looked inside while the dryer is attempting to dry and I see the ignitor glow and then go out. The dryer stopped drying after cleaning the lint trap so wondering if something broke during this. Should I replace the Thermistor or Thermostat?
