- We sell York Furnace Flame Sensor Part # S1-02527731701.
- Our York supplier told me that this flame sensor fits many of the older York Furnaces.
- The 02527731701 York Furnace Flame Sensor has a 40″ long yellow wire attached to it.
- One York furnace Model that I know this flame sensor fits is York model #ZP2UHD20N08001A.
- FYI: The most common problem that we see when a flames sensor is not working properly is: The furnace main gas burners ignite, the main gas burners stay on for only 8 to 10 seconds, then the burners shut right back off.
