Mounted to the coil, it protects your Lennox system from liquid refrigerant floodback, restricted airflow damage, and the efficiency losses that follow a frozen coil. It is engineered for direct compatibility with Lennox equipment that specifies this freeze-protection component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e a coil that ices over during operation, nuisance system shutdowns, the unit failing to restart after a freeze event, or a compressor that short-cycles. A drifted or open sensor may also cause the control board to lock out cooling entirely.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Lennox freeze controls are calibrated to precise trip and reset temperatures. An OEM \u003cstrong\u003e91W70\u003c\/strong\u003e guarantees the correct set points, connector, and probe geometry so the safety functions exactly as the factory intended — protecting your compressor and coil investment. Aftermarket substitutes often trip early or late, leaving equipment unprotected.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081078391155,"sku":"LNX-91W70","price":39.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-freezestat-coil-sensor-kit-91w70","provider":"National HVAC Parts","version":"1.0","type":"link"}
