Could a failing Gas Valve Solenoid Coil Kit cause the WHIRLPOOL WGD5620H to have symptom: Heats Few Minutes Then Cold?

The solenoid coils exhibit an intermittent open-circuit failure triggered by thermal expansion. During the initial operation, the coils function correctly, but the heat generated by the burner and the electrical resistance causes the internal windings to expand and lose continuity. This prevents the gas valve from reopening after the first cycle, resulting in cold air for the remainder of the drying period.

// ENGINEER'S LOG

Forensic analysis indicates a high-probability failure of the electromagnetic actuators (solenoids) on the gas control valve. The primary failure mode is a 'warm-open' condition where the coil insulation has degraded, allowing thermal expansion to break the circuit continuity only after a successful initial ignition. This prevents the secondary and holding coils from maintaining the valve seat in the open position during the 'maintain' phase of the drying cycle. Airflow should also be verified to ensure the high-limit thermostat is not being forced to cycle due to back-pressure, though the 'staying cold' symptom is more consistent with solenoid fatigue than thermostat cycling.
