Why Replace Your Flame Sensor Gasket?
Over time, gaskets can degrade due to heat cycling, leading to improper sealing around the flame sensor. A worn or damaged gasket may allow combustion gases to escape, cause nuisance lockouts, or compromise the accuracy of the flame sensing circuit. Replacing the gasket with a genuine OEM part restores proper function and extends the service life of your flame sensing components.
