Description
The Copeland Comfort Control 768A-842 is a silicon nitride hot surface ignitor engineered as a direct replacement ignition element for gas furnaces and heating systems that use advanced ceramic ignition technology. Silicon nitride ignitors represent a significant advancement over traditional silicon carbide elements, offering superior resistance to thermal shock, faster heat-up times, and a longer service life under the repeated high-temperature cycling demands of modern gas furnace ignition systems. The 768A-842 passes electrical current through the silicon nitride element, rapidly bringing it to ignition temperature to reliably light the gas-air mixture at the burner on each call for heat. The enhanced durability of silicon nitride construction makes this ignitor particularly well suited for high-cycle commercial applications and any installation where premature ignitor failure has been a recurring service issue. As an OEM-quality Copeland Comfort Control replacement component, the 768A-842 is a direct-fit solution for HVAC technicians servicing gas furnaces that specify silicon nitride ignition elements, minimizing diagnostic time and restoring reliable ignition performance during residential and commercial heating system service calls.
