The Spark of Life: Understanding Ignition

Just like our cars need a spark to start, gas furnaces rely on an ignition system to light the gas and keep you warm. This system includes the ignition module and the flame sensor. When you turn on the furnace, the ignition module sends a spark to the gas burner, igniting the fuel. The flame sensor then detects the presence of flame and sends a signal to the control board, telling it to keep the gas flowing.

When the Spark Goes Out: Common Causes of Ignition Failures

• Dirty Flame Sensor: Over time, dirt or debris can accumulate on the flame sensor, blocking its ability to detect the flame. A dirty flame sensor is like a blindfolded driver – it can’t “see” the flame and therefore shuts off the gas supply, leaving you in the cold.

• Faulty Ignition Module: The ignition module is the heart of the ignition system, sending out the sparks that ignite the gas. If it malfunctions, it won’t be able to generate the necessary spark, and your furnace will remain dormant.

• Gas Supply Issues: If there’s no gas flowing to the burner, your furnace won’t be able to ignite. Check if the gas supply has been turned off or if there are any leaks in the gas line.

Troubleshooting Ignition Failures: Step-by-Step

1. Check the Gas Supply: Start by ensuring that the gas supply is turned on. If it’s off, turn it back on and light a pilot light nearby to purge any air from the gas line.

2. Inspect the Flame Sensor: Remove the flame sensor from its socket and visually inspect it. If you see any dirt or debris, use a soft cloth or brush to clean it gently.

3. Test the Ignition Module: Most ignition modules have a small LED light that indicates if they’re functioning correctly. If the light isn’t on, the module may need to be replaced.

4. Reset the Furnace: Sometimes, a simple reset can solve the issue. Turn off the furnace at the circuit breaker or disconnect it from the power supply for a few minutes. Then, turn it back on and see if it ignites successfully.

When to Call the Pros:

If you continue to experience ignition failures after following these steps, don’t hesitate to contact a qualified HVAC technician. They have the expertise and equipment to diagnose and repair more complex issues, such as electrical faults or gas leaks.
