Gas dryer drum spins normally but produces no heat — igniter glows but gas valve never opens because the faulty sensor fails to send the 'hot enough' signal.
Burner ignites for approximately 1 minute then the flame shuts off unexpectedly mid-cycle, causing clothes to remain damp after a full cycle.
Dryer requires two or more full cycles to dry a normal load because the burner intermittently fires and cuts out due to an intermittent sensor failure.
A weak or failing flame sensor does not reliably signal the gas valve to close, allowing trace amounts of gas to linger near the burner assembly.
💡 Pro Tip: Diagnosing a Faulty Radiant Flame Sensor
Your part is likely the culprit if you notice any of the following:
⚠️ Gas dryer runs but produces no heat — drum spins yet clothes stay wet
⚠️ Igniter glows but the burner flame never lights or stays lit only briefly (1–2 min) before going out
⚠️ Dryer takes excessively long to dry a normal load — two or more full cycles
⚠️ Faint gas smell near laundry room — sensor failing to close the valve promptly
🔍 Test it yourself: Set your multimeter to continuity mode and probe both terminals of the sensor at room temperature. A healthy sensor shows continuity (beep/zero ohms). No continuity = confirmed bad sensor. Also consider replacing the gas valve coil kit (279834) and igniter (279311) at the same time for a complete burner assembly service.
