General Supply s1-02535354000 Flame Sensor

Product Description

The GENERAL SUPPLY s1-02535354000 is an OEM replacement flame sensor designed for York HVAC equipment. The flame sensor serves a critical safety function in gas-fired furnaces and heating systems: it detects the presence of a burner flame and signals the control board to keep the gas valve open. If no flame is sensed, the board shuts off the gas supply, preventing unburned gas accumulation. This part is installed by licensed HVAC technicians during routine maintenance or when a furnace exhibits symptoms such as short-cycling or lockout on ignition.

The s1-02535354000 flame sensor is intended for use in York gas furnaces and related York HVAC heating equipment. It is suited to residential heating applications where an OEM-specified replacement is required to maintain proper system operation and safety compliance. This sensor is a direct OEM replacement, meaning it matches the original factory specification for the equipment it serves.

Installation Notes

Flame sensor replacement is performed by a licensed HVAC technician. Before servicing, shut off electrical power to the furnace at the disconnect or breaker and close the manual gas shutoff valve. The sensor is typically secured with a single mounting screw and connected via a single wire lead. After installation, verify ignition sequence and confirm the control board is not displaying a fault code before returning the system to service.
