{"product_id":"oem-lennox-enthalpy-sensor-54g44","title":"OEM Lennox Enthalpy Sensor — 54G44","description":"\u003cp\u003eThe Lennox \u003cstrong\u003e54G44\u003c\/strong\u003e enthalpy sensor is a genuine OEM control component that measures both the temperature and humidity of outdoor air to calculate its total heat content (enthalpy). Your economizer uses this reading to decide when outdoor air is cool and dry enough to provide free cooling, reducing mechanical cooling runtime and lowering energy costs on your Lennox rooftop or packaged unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e the economizer failing to open when conditions are favorable, dampers stuck in a fixed position, higher-than-normal cooling bills, the unit running mechanical cooling when free cooling should be available, or erratic economizer switching. A drifting or failed sensor feeds bad data to the economizer logic, defeating its energy-saving purpose.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e the \u003cstrong\u003e54G44\u003c\/strong\u003e is calibrated to the exact response curve and wiring interface Lennox economizer controls expect. Substitute sensors can read inaccurately or communicate improperly with the logic module, leading to wasted energy and comfort complaints. The factory-correct Lennox part restores accurate free-cooling operation. In stock and ships same day.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081102999923,"sku":"LNX-54G44","price":24.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-enthalpy-sensor-54g44","provider":"National HVAC Parts","version":"1.0","type":"link"}
