The Flame Sensor on Your Dunkirk 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 Dunkirk systems — including models such as Q90-200, XEB, PWX — a failing flame sensor often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Dunkirk part.
