This cable carries high-voltage electrical signals from the ignition control module to the gas burner assembly, generating the spark needed to ignite the burner safely and reliably. HVAC technicians and service professionals rely on this type of ignition cable to restore proper ignition function in a wide range of residential and commercial heating equipment.\u003c\/p\u003e\u003cp\u003eThe 100271890 is constructed with a core conductor, an insulating layer, and a protective outer jacket. This layered design shields the high-voltage signal from electrical interference and prevents short circuits, ensuring clean and consistent spark delivery every ignition cycle. A degraded or failed ignition cable is a common cause of ignition lockout faults, no-heat calls, and repeated ignition failures. Replacing a worn cable with an OEM-spec part like this one restores reliable ignition performance and reduces nuisance service callbacks.\u003c\/p\u003e\u003cp\u003eThis cable is manufactured to match the original equipment specifications for compatible Lochinvar and AO Smith appliances. Using an OEM or OEM-equivalent ignition cable ensures the correct length, terminal connections, and insulation rating for the intended application. When diagnosing ignition problems, technicians should inspect the spark ignition cable for cracks, carbon tracking, damaged boot ends, and insulation breakdown. A faulty cable can cause weak spark, misfires, or complete ignition failure even when the igniter and control module are functioning correctly.\u003c\/p\u003e\u003cp\u003eThis part weighs approximately 0.09 pounds, making it a lightweight and easy-to-carry replacement cable for field service work. It is a straightforward swap that requires no special tools beyond standard hand tools, making it a practical choice for technicians performing scheduled maintenance or emergency repair calls on gas heating equipment.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDirect OEM replacement spark ignition cable for compatible AO Smith and Lochinvar gas appliances\u003c\/li\u003e\n\u003cli\u003eCarries high-voltage signals from ignition module to burner, generating a reliable spark for safe gas ignition\u003c\/li\u003e\n\u003cli\u003eInsulated construction resists electrical interference and prevents short circuits during ignition cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe AO Smith 100271890 Spark Ignition Cable restores reliable ignition function in gas boilers, furnaces, and water heaters.
