How do I know if my York spark ignitor is failing?
If the control board displays an ignition failure code and you do not hear a clicking sound or see a spark at the burner, the electrode or ceramic body may be cracked. High-resistance readings or visible carbon tracking on the ceramic insulator are also clear indicators that replacement is necessary.

Is the S1-025-27759-700 compatible with other brands?
While York parts are often found in Coleman, Luxaire, and Fraser-Johnson equipment, always verify the specific OEM part number against your unit's data plate to ensure proper fit and voltage compatibility.

Does this ignitor include the mounting hardware?
Typically, this spark ignitor electrode is supplied as the replacement component itself. It is recommended to retain and inspect existing mounting brackets and screws for corrosion before reinstallation.
