Description

York OEM 18AWG Flame Sensor Wire

Keep your York furnace running safely and efficiently with the genuine OEM York S1-373-03481-717 18AWG Flame Sensor Wire. Designed as a direct replacement for York heating systems, this flame sensor wire ensures a secure, low-resistance connection between the flame sensor and the furnace control board — a critical link in your system’s safety circuit.

Why the Flame Sensor Wire Matters

The flame sensor wire carries the microamp signal generated by the flame sensor rod back to the furnace control board. A degraded, cracked, or broken wire can cause nuisance lockouts, intermittent heating failures, or unsafe operating conditions. Replacing it with the correct OEM part restores proper signal integrity and system reliability.
