SOURCE1 2535354000 Flame Sensor 2.5 X 0.75 Inches Replacement S1-02535354000

Product Description

The SOURCE1 2535354000 is an OEM replacement flame sensor designed for use in York and SOURCE1 branded gas furnaces and heating systems. A flame sensor is a critical safety component in any gas-fired furnace. It detects the presence of a burner flame during the ignition sequence. When the furnace calls for heat, the control board opens the gas valve and triggers ignition. The flame sensor then confirms that combustion is actually taking place. If the sensor does not detect a flame within a set time window, the control board shuts off the gas valve to prevent unsafe gas buildup. This makes the flame sensor one of the most important safety controls in a residential or light commercial heating system. Over time, flame sensors develop a thin layer of oxidation on the sensing rod. This coating insulates the rod and prevents accurate flame detection. The result is a furnace that lights briefly and then shuts down, often called short cycling. Replacing the sensor with a direct OEM replacement like the SOURCE1 2535354000 restores reliable ignition and steady furnace operation. HVAC technicians and service professionals rely on OEM-grade sensors to maintain the performance and safety standards the original manufacturer designed into the system. This sensor measures 2.5 inches in length, 2.5 inches in width, and 0.75 inches in height, and weighs 0.1 pounds, making it a compact and easy-to-handle part during service calls. It is a direct fit for compatible York furnace models, reducing diagnostic time and simplifying the repair process. Always confirm model compatibility before installation.
