White-Rodgers 789A-914A1 Silicon Nitride Hot Surface Ignitor, 120V

The White-Rodgers 789A-914A1 is a 120 V silicon nitride hot surface ignitor. When the furnace control energizes it, the element heats to ignition temperature and lights the burners as the gas valve opens; silicon nitride elements are tougher than silicon carbide and stand up better to handling, vibration and repeated cycling. This is a genuine White-Rodgers replacement part.

Confirm that your furnace's parts list calls for 789A-914A1 before ordering, since ignitor length, mounting and connector differ between models.
