Igniter/Glow Bar: The Spark of Heat

The igniter, often a glow bar, is responsible for initiating the combustion process. When the dryer's control board sends a signal, the igniter heats up, becoming hot enough to ignite the gas.

Visually inspect the igniter for cracks or breaks. If damaged, it won't heat up sufficiently. Testing for continuity with a multimeter is crucial to determine if the igniter is functioning correctly. If there's no continuity, the igniter requires replacement.

Flame Sensor: Confirming the Flame

The flame sensor is a safety device that monitors the presence of a flame within the burner assembly. It is usually a small metal rod positioned in the path of the flame.

Once the igniter ignites the gas, the flame sensor detects the heat and sends a signal to the control board to keep the gas valve open. If the flame sensor doesn't detect a flame, it will signal the control board to shut off the gas supply, preventing unburned gas from accumulating. A faulty flame sensor can cause the dryer to shut off prematurely or fail to heat at all.

Gas Valve Functionality: Controlling the Flow

The gas valve regulates the flow of gas to the burner assembly. It's controlled by the dryer's control board, which sends signals to open or close the valve based on the dryer's heating cycle.

The gas valve typically has one or two solenoids. These solenoids are electromagnetic switches that open and close the valve. Testing the solenoid for continuity with a multimeter is essential to ensure proper valve operation. A lack of continuity suggests a faulty solenoid and the need for valve replacement.

Ventilation/Airflow: Expelling Moisture

Proper ventilation is critical for a gas dryer's performance and safety. The ventilation system expels hot, moist air from the dryer, preventing overheating and ensuring efficient drying.

A blocked or restricted vent can cause lint buildup, overheating, and even fires. Regularly inspect the vent duct for obstructions and clean it thoroughly. Ensure the vent is not crushed, kinked, or excessively long.

To confirm proper ventilation, disconnect the vent from the back of the dryer and run the dryer on a timed dry cycle. If the dryer heats properly with the vent disconnected, the problem likely lies within the venting system.
