This single component stores and releases energy to keep both motors operating smoothly and at rated efficiency, making it one of the most critical parts in your air conditioning or heat pump system.\u003c\/p\u003e\u003cp\u003eCapacitors are among the most common HVAC failure points. Common symptoms of a failing \u003cstrong\u003e21W82\u003c\/strong\u003e include a compressor or fan that hums but won't start, intermittent cooling, a unit that trips the breaker, a swollen or leaking capacitor top, or a hard-starting compressor that clicks on and off. Because a weak capacitor forces motors to draw excess current, a bad unit left unreplaced can lead to premature and costly compressor failure.\u003c\/p\u003e\u003cp\u003eChoosing an OEM Lennox capacitor matters. The \u003cstrong\u003e21W82\u003c\/strong\u003e is manufactured to the exact microfarad (MFD) and voltage ratings specified for your Lennox equipment, ensuring proper motor performance, safe operation, and full system efficiency. Generic substitutes with mismatched ratings can shorten motor life and void equipment warranties. Insist on the factory-correct part for a reliable, long-lasting repair.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081112600947,"sku":"LNX-21W82","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-round-dual-LNX-21W82.jpg?v=1783760434","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-21w82","provider":"National HVAC Parts","version":"1.0","type":"link"}
