Why Replace the Flame Sensor Wire Harness?
Over time, wire harnesses can suffer from heat degradation, cracked insulation, corroded terminals, or loose connections — all of which can cause intermittent flame signal loss, nuisance shutdowns, or failure to ignite. Replacing the harness with a genuine OEM part restores the integrity of the flame detection circuit and helps ensure the appliance operates safely and efficiently.
