Lennox 14K99 Electrode-Ignitor the 661049R ensures a factory-specThe Lennox 14K99 Electrode Ignitor is an essential OEM component engineered to maintain precise spark ignition sequences in high performance gas furnaces. As a high voltage furnace ignitor replacement, this part is built with a heavy duty ceramic insulator and a durable metal alloy probe to withstand the extreme thermal stresses of the combustion chamber. When a gas furnace won't light, a fouled or cracked electrode is often the culprit, leading to
