During the ignition cycle, your gas furnace goes through a process where a spark or a hot surface ignitor will actually ignite the gas. As the gas is ignited, the flame sensor creates a current of electricity. The electricity is calculated in micro amps. If the furnace’s control board does not read the proper level of micro amps, the furnace will no longer give the system fuel to avoid an explosion.\u003c\/p\u003e\n\u003cp\u003eOver time, if the flame sensor is not cleaned properly, oxidation or carbon buildup can restrict the flame sensor’s ability to work properly, which can result in a malfunction of the furnace.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cspan\u003eUse the \u003c\/span\u003eLennox 52W29 Furnace Flame Sensor\u003cspan\u003e \u003c\/span\u003e\u003cspan\u003ewith most series of models  -G40, G43, G50, G51, G60. \u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eReplaces 31L71, 31L7101 \u0026amp; LB-74940A\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eBreathe easy with the PureFilters Promise\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eClean indoor air is essential to our well-being, and Canadians deserve a company that offers products to help them live a healthier life. PureFilters was founded with one mission - to help Canadians enjoy clean and healthy indoor air at an affordable price. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eFrom quality products to hassle-free returns, to superior customer service - our team at PureFilters is ready to help you with your order.
