A run capacitor stores and releases electrical energy to provide the continuous phase shift a single-phase motor needs to start and run efficiently. In your Lennox condenser or air handler, this capacitor supports the compressor or fan motor, keeping current draw in check and the motor running at its rated torque and speed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A hard-starting or humming motor that won't spin, a condenser fan that needs a push to start, warm air from the supply registers, tripped breakers, or a compressor that clicks on and off. A bulged, leaking, or swollen capacitor top is a clear sign of failure — capacitors weaken over time from heat and electrical cycling and are one of the most common HVAC service replacements.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Capacitance (µF) and voltage ratings must match the motor's design. An undersized or mismatched capacitor causes overheating, reduced efficiency, and premature motor burnout. Installing the exact OEM \u003cstrong\u003e22W78\u003c\/strong\u003e capacitor guarantees the correct microfarad and voltage rating for your Lennox unit, protecting the motor and restoring full performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081089696115,"sku":"LNX-22W78","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-round-single-LNX-22W78.jpg?v=1783763564","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-single-run-capacitor-22w78","provider":"National HVAC Parts","version":"1.0","type":"link"}
