Gas dryer runs and tumbles normally but produces no heat. The solenoid coils have failed open-circuit and can no longer energize the gas valve to allow fuel flow to the burner.
Dryer heats for a short period then stops mid-cycle. A weakened coil opens the valve initially but loses continuity when it reaches operating temperature.
The igniter glows orange and then shuts off without the burner igniting. This is the classic signature of a failed Boost-Hold or Secondary coil preventing the gas valve from opening.
An audible clicking or ticking sound comes from the burner area but no flame appears. The coils are receiving a signal but cannot mechanically open the valve due to failed windings.





💡 Pro Tip: How to Confirm a Bad Gas Valve Coil
Your part is likely the culprit if you notice any of the following:
⚠️ Dryer runs and tumbles but produces zero heat
⚠️ Igniter glows orange, then shuts off without gas igniting — classic bad coil signature
⚠️ Dryer heats for the first 10–15 minutes then stops heating mid-cycle
⚠️ Gas valve clicking or ticking noise without a visible burner flame
🔍 Diagnostic tip: Set a multimeter to resistance (Ω) mode. A good Boost-Hold coil reads ~1,300 Ω; a good Secondary coil reads ~530 Ω. An open reading (OL) on either coil confirms it needs replacement. Always shut off the gas supply and unplug the dryer before testing or replacing.
