Common questions
What does a hot surface igniter do?
It glows hot to light the gas and air mixture at the burners. If it is cracked or no longer heats, the furnace will usually not light.
How do I confirm this igniter fits my furnace?
Match the number on the old igniter and check your furnace manual or parts list for the igniter number. You can also send us your unit's model and serial number.
Is S1-02545231000 the same as 025-45231-000?
Yes. They are the same York Source 1 part written with and without dashes.
Any handling tips?
Disconnect power before replacing the igniter. Handle the element carefully, because silicon nitride igniters can break if bumped or dropped.
