The Flame Sensor on Your Giant Boiler

The flame sensor (flame-rectification probe) confirms a flame is actually burning. If it cannot detect flame, the control shuts the gas off within seconds. A dirty or failed sensor causes the boiler to light then drop out repeatedly.

On Giant systems — including models such as Cascade, Super Cascade, Expert — a failing flame sensor often shows up as no hot water or related symptoms. We diagnose it precisely and install the correct genuine Giant part.
