It provides the phase-shift torque that starts and steadily runs both your compressor (40 MFD side) and outdoor condenser fan motor (10 MFD side), keeping your Lennox air conditioner or heat pump operating at rated efficiency.\u003c\/p\u003e\u003ch3\u003eCommon Failure Symptoms\u003c\/h3\u003e\u003cp\u003eA weak or failed capacitor is one of the most common HVAC service calls. Watch for a compressor or fan motor that hums but won't start, a condenser fan that spins slowly or intermittently, a hard-starting compressor, breaker trips, or a visibly bulged, leaking, or domed top on the old capacitor. Capacitance drifts below spec long before total failure, so a marginal \u003cstrong\u003e33W99\u003c\/strong\u003e can cause weak cooling and higher energy bills.\u003c\/p\u003e\u003ch3\u003eWhy OEM Matters\u003c\/h3\u003e\u003cp\u003eChoosing the factory-spec \u003cstrong\u003e33W99\u003c\/strong\u003e guarantees the exact 40+10 MFD dual rating, 370V tolerance, and oval footprint your Lennox unit's mounting bracket and control box were built for. Aftermarket substitutes with mismatched microfarad values or voltage ratings shorten motor life and can damage the compressor. Genuine OEM protects your equipment and preserves warranty compliance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081126265203,"sku":"LNX-33W99","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-oval-dual-LNX-33W99.jpg?v=1783760337","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-dual-run-capacitor-40-10-mfd-370v-oval-33w99","provider":"National HVAC Parts","version":"1.0","type":"link"}
