User Suggested Solutions

Check for gas leaks by inspecting the gas line and connections. Use soapy water to identify leaks; bubbles will form where gas is escaping. If a leak is found, turn off the gas supply and contact a professional.
Inspect the gas valve and burner assembly for any signs of damage or malfunction. If damaged, replace the faulty parts. Ensure the dryer is unplugged and the gas supply is turned off before attempting repairs.
Ensure proper venting of the dryer. Check that the vent hose is not kinked or blocked and that the outside vent flap opens freely. Clean any lint buildup that may be obstructing airflow.
