The TAILWIND 100187882 is a flame sensor with gasket designed as a genuine OEM replacement part for water heater service. The flame sensor detects the presence of a burner flame and sends a signal to the control system to confirm ignition. Without a functioning flame sensor, the control board will shut down the burner as a safety precaution. This part ships in original factory packaging and is installed by licensed plumbers or HVAC-R technicians during routine water heater maintenance or troubleshooting of ignition and lockout faults.
This flame sensor with gasket is used in residential and light commercial water heater applications where direct spark or hot surface ignition systems are employed. It is suited for gas-fired water heater models that require an exact OEM-spec replacement rather than a generic or universal substitute. Installers typically encounter this part when diagnosing a unit that cycles into lockout, fails to ignite, or throws a flame-sensing fault code.
This is an OEM-style replacement flame sensor for specific gas-fired water heater models and serial number ranges. This part is not a universal or generic replacement. Verify the exact model and serial number of the unit before installation to confirm fitment.
Installation should be performed by a licensed plumber or qualified HVAC-R technician. Shut off the gas supply and disconnect power to the water heater before beginning any service work. The old gasket should be removed completely and the mounting surface cleaned before seating the new gasket and sensor. Follow all applicable local codes and the manufacturer service documentation for torque and reassembly procedures.
