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.
• gas valve issue: Often seen in systems that are overdue for maintenance or operating under excessive load.
• 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.
• control board error: This cause typically requires professional diagnostic equipment to confirm.
