York S1-025-53193-000 Sensor Flame 90 Degree Bend

Description

The York S1-025-53193-000 is an OEM replacement flame sensor featuring a 90-degree bend configuration, engineered specifically for compatible York heating systems. Flame sensors play a critical role in furnace safety and operation — they detect the presence of a burner flame and signal the control board to keep the gas valve open. Without a properly functioning flame sensor, the furnace will shut down on lockout, preventing unsafe gas accumulation.

Key Features

• OEM York replacement part — ensures proper fit and reliable performance
• 90-degree bend design for precise positioning within the burner assembly
• Detects burner flame to confirm safe ignition and continuous operation
• Helps prevent nuisance lockouts caused by a worn or contaminated sensor
• Direct drop-in replacement for compatible York furnace models

Application

This flame sensor is designed for use in York gas furnaces that require the S1-025-53193-000 part number. Always verify compatibility with your specific furnace model before installation. Replacing a faulty or carbon-coated flame sensor is one of the most common and cost-effective furnace repairs, restoring reliable ignition and preventing unnecessary service calls.
