Why Replace Your Flame Rod?
Over time, flame rods can accumulate oxidation or carbon deposits that degrade their ability to conduct the small rectified current used to verify flame presence. A compromised flame rod causes the control board to interpret a no-flame condition, triggering lockout or repeated ignition attempts. Replacing the flame rod with a genuine Rinnai OEM part is the most reliable way to resolve these symptoms and return your tankless water heater to peak operating condition.
