Direct answer
Dryer gas ignition system ignites and controls the burner through interlocked safeties. Related symptoms include no heat, intermittent heat, clicking or gas odor. Those symptoms do not prove the component failed: verify airflow, gas supply position and observable ignition sequence.
What this covers
- gas dryers
- The exact condition described in the title
- Customer-accessible checks before internal repair or reset
What it does not cover
- ×A different brand, model family or similar-looking code
- ×Internal live-electrical, gas, refrigerant or sealed-system testing
- ×A guarantee that a named component has failed without isolation
