    Diagnosing Pilot Light Ignition Failures

    When your boiler refuses to ignite, the pilot light is often the culprit. Understanding the common reasons for pilot light ignition failures is essential for effective troubleshooting. This section will guide you through the diagnostic steps needed to identify and resolve the issue, ensuring your heating system operates smoothly once again.

    Before taking any action, it’s crucial to pinpoint the specific cause of the pilot light not igniting. Common issues include:

    • Faulty thermocouple: This safety device detects whether the pilot light is lit and shuts off gas if it isn’t. A malfunctioning thermocouple may prevent the pilot light from staying lit.

    • Dirty pilot orifice: Dust and debris can clog the orifice, disrupting the gas flow necessary for ignition.

    • Defective ignition module: If the ignition module fails, it may not send the spark needed to ignite the gas.

    • Closed gas valve: Ensure that the gas supply is turned on. A closed valve will prevent gas from reaching the pilot light.
