This single component stores and releases energy to keep both motors operating smoothly, making it one of the most critical parts in your air conditioner or heat pump.\u003c\/p\u003e\u003cp\u003eWhen the \u003cstrong\u003e89M91\u003c\/strong\u003e capacitor fails, you may notice the compressor or fan motor humming but not starting, the outdoor unit tripping the breaker, warm air from the vents, or a swollen, bulging, or leaking capacitor top. A weak capacitor forces motors to draw excess current, which can lead to premature compressor failure if left unaddressed.\u003c\/p\u003e\u003cp\u003eChoosing an OEM Lennox part matters. The \u003cstrong\u003e89M91\u003c\/strong\u003e is built to the exact microfarad (µF) and voltage ratings your Lennox system was engineered for, ensuring correct startup torque, rated efficiency, and long service life. Generic aftermarket capacitors often drift out of tolerance and can void warranty coverage. Install the factory-matched replacement for reliable, code-compliant performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081092088179,"sku":"LNX-89M91","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-89M91.jpg?v=1783760506","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-89m91","provider":"National HVAC Parts","version":"1.0","type":"link"}
