Ignition Problems: Sparking Solutions for a Quick Start

A gas fireplace needs a spark to ignite the gas flowing to the burner. If you hear the gas flowing, but the flames don’t ignite, the problem likely lies within the ignition system. The two primary components we’ll focus on are the igniter and the flame sensor.

Diagnosing Igniter Issues

The igniter’s job is to create the spark that ignites the gas. The most common symptom of an igniter problem is a lack of any sparking sound when you attempt to start the fireplace.

Checking the Igniter Wire Connection

Start by visually inspecting the igniter wire. This wire connects the igniter to the control module. Make sure the wire is securely connected at both ends.

Look for any signs of damage, such as frayed wires or corrosion. A loose connection or damaged wire can prevent the igniter from receiving the necessary power to create a spark.

If you find a loose connection, gently reattach it. If the wire is damaged, it will need to be replaced.

Replacing the Igniter

If the wire is intact and properly connected, but the igniter still isn’t sparking, the igniter itself may be faulty. Replacing an igniter is a straightforward process that usually involves removing a mounting bracket, disconnecting the old igniter, connecting the new igniter, and securing it in place.

Always turn off the gas supply to the fireplace and disconnect the power before attempting any repairs. Refer to your fireplace’s owner’s manual for specific instructions.

Understanding Flame Sensor Malfunctions

The flame sensor is a safety device that detects the presence of a flame. If the flame sensor doesn’t detect a flame, it will shut off the gas supply to prevent gas from building up.

Cleaning the Flame Sensor

Over time, the flame sensor can become coated with soot or debris, which can prevent it from properly detecting the flame.

A dirty flame sensor is a common cause of ignition problems.

To clean the flame sensor, gently wipe it with a clean, dry cloth or fine steel wool. Be careful not to damage the sensor.

Replacing the Flame Sensor

If cleaning the flame sensor doesn’t resolve the issue, the sensor itself may be faulty and need replacing. Flame sensors can degrade over time. Replacing the flame sensor is similar to replacing the igniter. Disconnect the power and gas, then remove the mounting bracket, disconnect the old sensor, connect the new sensor, and secure it.
