Lennox 88A12 Flame Sensor Wire

The Lennox 88A12 Flame Sensor Wire is a critical OEM component designed to facilitate the low-voltage microamp signal transmission between the flame rod and the integrated furnace control board. Engineered as a direct replacement, the 88A12 is identical to 88A1201, ensuring seamless HVAC part compatibility for technicians servicing Lennox G34, G42, G61, and EL280UHE series units. This 30-inch flame sensor lead features high-temperature insulation to withstand the rigorous thermal environment within the burner vestibule, preventing signal degradation or short-to-ground faults that lead to nuisance lockouts. Proper installation of this genuine Lennox 88A12 wire is essential for maintaining the flame rectification process, ensuring the ignition system accurately detects the presence of a flame to prevent unburned gas accumulation. When troubleshooting intermittent ignition failures or "no flame sensed" codes, replacing a brittle or carbon-tracked 88A12 wire often restores system reliability without requiring a full board replacement.

• Universal Compatibility: Serves as the factory-spec Lennox 88A1201 equivalent for a wide range of residential furnaces.
• High-Heat Durability: Constructed with heat-resistant insulation to prevent wire hardening and cracking near the burner assembly.
• Signal Integrity: Minimizes electrical resistance to ensure the flame signal microamps reach the controller within the required 1.5 to 5.0 µA range.
• OEM Precision: Features pre-terminated connectors for a secure, vibration-resistant fit on Lennox flame sensors.

• How can I tell if my flame sensor wire is failing? Look for visible signs of scorched insulation or brittle sections. If your furnace ignites then shuts down after a few seconds despite a clean sensor rod, the flame sensor wire may be failing to carry the rectification signal.
• Is the Lennox 88A12 interchangeable with other wires? While some lead wires appear similar, using the OEM 88A12 ensures the correct gauge and terminal fitment specific to Lennox furnace ignition systems.
• Does this wire include the sensor rod? No, this is the 88A12 flame sensor wire only. It connects the existing sensor rod to the main control board.
