Understanding Boiler Not Firing / Starting

Boiler Not Firing / Starting occurs when your boiler is receiving power but the burner will not fire up. This is one of the most common service calls our team receives throughout Greater Vancouver. The severity can range from a minor inconvenience to a complete system shutdown depending on the underlying cause. Early diagnosis and repair often prevent more extensive damage and more costly repairs down the road.

Common Causes of Boiler Not Firing / Starting

Several factors can cause boiler not firing / starting. The most common causes our technicians encounter across Greater Vancouver homes include:

• ignition failure: The most frequent root cause found during diagnostic service calls.

• flame sensor fault: Can develop gradually over months or years of system operation.
• air pressure switch fault: Less common but can indicate a developing problem that should be addressed soon.

Identifying the specific cause requires systematic testing. Our technicians use manufacturer-specific diagnostic procedures to pinpoint which component has failed or which condition triggered the symptom. Most boiler not firing / starting diagnoses are completed within 30-45 minutes of arrival.
