White-Rodgers 21D64-5PK HSI

When you're out on a service call dealing with a cracked silicon carbide igniter, the White-Rodgers 21D64-5PK HotRod is the professional-grade solution to keep on your truck. This 5-pack of 120V silicon nitride igniters is designed specifically for high-efficiency gas furnaces, boilers, and water heaters. Unlike brittle carbide models, the nitride construction in this universal hot surface igniter handles the thermal stress of modern ignition cycles without the high failure rate, drastically reducing those annoying callbacks. Each 21D64-2 upgrade kit included in this pack comes with a universal breakaway mounting bracket and porcelain wire nuts, making it a drop-in replacement for over 150 OEM parts, including Honeywell Glowfly and various Norton or CoorsTek models. With a 15.5-inch lead length and a 17-second minimum ignition timing, this furnace igniter 5-pack ensures secure, consistent performance across integrated and non-integrated systems. Stop wasting time chasing down specific OEM part numbers; this universal kit provides the durability and compatibility needed to get the heat back on fast.

Key Benefits:

• Universal Compatibility: Engineering-tested to replace over 150 silicon carbide igniters from major brands like Carrier, Goodman, and Trane.
• High-Durability Nitride: Silicon nitride material resists oxidation and provides superior physical strength compared to traditional spiral or flat carbide igniters.
• Streamlined Installation: Features a universal breakaway bracket and 15.5" leads with stripped ends to accommodate varying mounting configurations and cabinet depths.
• Complete Upgrade Kit: Each pack contains five individual 21D64-2 kits, including mounting screws, ceramic wire nuts, and technical instructions.
• Electrical Reliability: Rated for 102-132 VAC, 60 Hz operation with a maximum load of 3.0 A at 132 VAC.

Common Questions:

• Can I use this to replace a spiral-type carbide igniter? Yes, the 21D64-2 is designed specifically to convert both flat and spiral 120V silicon carbide igniters to the more durable nitride technology.
• Does this require a power adapter module? No, this silicon nitride upgrade kit is engineered for direct connection within the existing HSI circuit, eliminating the need for additional power modules.
• Will it fit my Carrier furnace? In most cases, yes. The included universal bracket and extension mounting options are designed to align the igniter correctly within the burner flame path of most OEM furnace brands.
