Identifying Ignition Failure Causes
When your boiler fails to ignite, understanding the underlying causes is crucial for effective troubleshooting. This section delves into common ignition failure issues, helping you diagnose the problem swiftly and accurately. By pinpointing the root cause, you can take the necessary steps to restore your heating system efficiently.
Understanding the root causes of ignition failures is essential for effective repairs. Common culprits include:
Faulty ignition electrode: This component creates the spark needed to ignite the gas. If damaged or dirty, it may fail to produce a spark.
Gas supply issues: Insufficient gas flow can prevent ignition. Check the gas valve and supply line for blockages.
Blocked flue: A blocked flue can restrict airflow, causing the boiler to shut down for safety reasons.
Air in the system: Trapped air can disrupt the ignition process. Bleeding the radiators may resolve this.
Step-by-Step Fix for Boiler Ignition
