Lennox 62K50 Flame Sensor Kit

The Lennox 62K50 Dual Rod Flame Sensor Kit is an essential OEM replacement component designed for precise flame supervision in high-efficiency gas furnaces and boilers. This kit, which is technically identical to Lennox 62K5001, features a high-grade stainless steel flame rod and a galvanized steel mounting bracket to ensure structural integrity within the high-heat environment of the burner assembly. As a specialized HVAC flame detection sensor, it utilizes the principle of flame rectification to send a microamp signal to the SureLight integrated control board, confirming stable combustion and preventing hazardous gas buildup.

For technicians performing a Lennox furnace flame sensor replacement, this kit is highly versatile, fitting a wide range of models including the 80MGF, G24E, G24M, and G25MV series. The package includes multiple burner mounting brackets (13", 16-7/8", and 19-5/8"), a 43-inch ground wire lead, and high-temperature resistant wiring to ensure a reliable furnace ignition system interface. Proper installation of this Lennox 62K50 kit is critical for resolving "no flame" diagnostic codes and ensuring the gas burner safety sensor maintains the necessary 0.61 microamp signal for continuous operation.

• Universal Compatibility: Engineered as a direct replacement for 62K5001 and LB-79982C, fitting numerous Lennox and Allied Air furnace models.
• Enhanced Signal Reliability: High-purity stainless steel rods minimize oxide buildup, ensuring consistent microamp feedback to the control module.
• Robust Construction: Heat-resistant ceramic insulators prevent electrical leakage to ground, maintaining system safety in extreme temperatures.
• Comprehensive Kit: Includes a 73K3801 spark ignitor, 43K5301 dual rod sensor, and multiple brackets for seamless field adaptation.

• Why is my furnace shutting down after a few seconds of ignition? This often indicates a fouled or failing Lennox 62K50 flame sensor that is unable to prove the flame to the control board.
• Is the 62K50 compatible with 62K5001? Yes, these are identical part numbers used interchangeably in Lennox technical literature and parts catalogs.
• Can I clean the dual rod sensor instead of replacing it? While temporary cleaning with light abrasive material may restore the signal, permanent replacement is recommended if the ceramic is cracked or the rod is severely pitted.
