Gas dryer runs and drum spins normally but produces zero heat. The solenoid coils have failed open and can no longer energize to open the M-series gas valve, preventing gas from reaching the burner assembly.
Burner lights at the start of a cycle but flame extinguishes after 15–60 seconds and does not re-light. Coils may pass a cold resistance test yet fail intermittently once they reach operating temperature.
Clothes require multiple cycles to dry completely. A weakened secondary coil allows only partial gas valve opening, reducing gas flow and heat output below normal drying temperatures.
Dryer timer stalls or does not advance at the expected rate during the drying cycle. Insufficient heat generation caused by faulty coils prevents the thermostat from cycling normally, stalling timer progression.
💡 Pro Tip: How to Confirm Your Gas Valve Coils Are Bad
Your part is likely the culprit if you notice any of the following:
⚠️ Dryer runs but produces no heat — drum spins but clothes stay wet
⚠️ Igniter glows orange/white hot, then shuts off without the gas burner lighting
⚠️ Flame ignites at start of cycle, then goes out after 15–60 seconds and never re-lights
⚠️ Cycles take 2× longer than normal; timer does not advance at the expected rate
🔬 Diagnostic tip: Use a multimeter on the coil terminals at operating temperature — coils can test good when cold but fail open when hot. Always replace both coils at the same time; the manufacturer recommends replacing the full kit together. If the igniter glows brightly but gas never flows, these coils are the #1 suspect.
