You should have a spare at all times
These ceramic igniters crap out about every 4-5 years,,<br />They seem to be made gy one manufacturer and branded by a bunch of resellers,<br />They all work fine, and are relatively easy to install depending one where they are located inside the furnace, Make sure the device is mounted securely, it usually snaps into place, I neglected to snap it properly and it didn't last long, My fault,
