Gas Valve Solenoid Coil Kit
When the dryer first starts, the solenoids are cold and can generate enough electromagnetic force to lift the gas valve plungers. After several minutes of operation, the heat from the burner and the internal electrical resistance of the coils cause the copper windings to expand, breaking continuity in failing units. This results in the gas valve closing and failing to relight for the remainder of the cycle.

High Limit Thermostat
If the dryer's airflow is restricted, the high-limit thermostat will trip to prevent overheating. If the thermostat has become out of calibration (electromechanical fatigue), it may trip at a lower temperature than designed, cutting power to the burner assembly prematurely before the clothes are dry.

Flame Sensor
The flame sensor (radiant sensor) monitors the heat from the igniter or the flame. If the sensor is faulty or covered in soot/debris, it may incorrectly signal the gas valve to close because it fails to detect the infrared heat signature required to maintain the burner circuit.
