Lennox Ignition Wire for Gas Furnaces

Lennox ignition wire for gas furnaces is a replacement ignition lead, also called an ignition cable or spark electrode wire. It carries the high-voltage signal from the furnace ignition control to the ignition system. Replacing a worn or damaged lead helps the furnace light reliably at the start of each heating cycle.

Key Features:

• Lennox-branded replacement part for gas furnace ignition systems
• Insulated ignition lead that carries the ignition signal between the control and the ignition components
• Direct-replacement design for restoring ignition performance on worn, cracked, or damaged leads
• Available in multiple lead configurations, each with its own part number

A damaged ignition wire can cause intermittent lighting, repeated ignition attempts, or a furnace that won't start. Replacing the wire with a Lennox part helps return the ignition circuit to proper operation. Always disconnect power to the furnace before servicing, and follow Lennox service guidelines or have a qualified HVAC technician do the work.
