Lennox 88A12 Flame Sensor Wire
The Lennox 88A12 Flame Sensor Wire is a genuine OEM replacement part designed to maintain reliable flame sensing in Lennox furnace systems. A properly functioning flame sensor wire is critical to safe furnace operation — it carries the low-voltage signal from the flame sensor rod to the control board, confirming burner ignition and allowing the system to continue its heating cycle. Using an OEM-matched replacement ensures correct fit, proper electrical continuity, and long-term durability in your Lennox equipment.

Why Replace Your Flame Sensor Wire?
Over time, flame sensor wires can become brittle, cracked, or damaged due to repeated heat cycling inside the furnace cabinet. A compromised wire can cause intermittent flame sensing failures, leading to furnace lockouts, nuisance service calls, and potential safety concerns. Replacing the wire with a genuine Lennox part restores system integrity and ensures the control board receives an accurate flame signal every time.
