The run capacitor stores and releases the electrical charge that keeps the blower or fan motor running at proper speed and efficiency. When this capacitor weakens or fails, symptoms typically include a humming motor that won't spin up, intermittent shutdowns, slow or labored motor starts, and reduced airflow — all of which can quickly cascade into motor burnout if left unaddressed.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 15 MFD (microfarad) | 370V rated | Oval case form factor | 50\/60 Hz | UL-approved current interrupter | Non-PCB dielectric fluid | Factory-matched ±5% tolerance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier\/Totaline OEM-sourced capacitor built to exact factory tolerances. Generic alternatives often carry wider MFD variance (±10%), which increases motor operating temperature, shortens bearing life, and can void system warranties.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall Difficulty: 2\/5\u003c\/strong\u003e — Discharge the capacitor fully before removing any wires. Tools needed: 1\/4\" nut driver or flathead screwdriver, insulated needle-nose pliers, and a multimeter to verify capacitance. Always photograph wire connections before disconnecting.

Confirm the MFD rating and voltage on your unit's data plate before ordering — using an incorrectly rated capacitor can damage the motor. Note: Some distributors list P291-1503 as superseded by P291-1504 (upgraded to 440V); our team can confirm the correct fitment for your unit before you order. Have questions? Contact us — we verify part fitment at no charge.\u003c\/p\u003e","brand":"Carrier","offers":[{"title":"OEM","offer_id":62643342180723,"sku":"CARRIE-PF1MNB060000AAAA-CAPACITOR-P291-1503","price":28.95,"currency_code":"USD","in_stock":true},{"title":"Generic","offer_id":62643342213491,"sku":"CARRIE-PF1MNB060000AAAA-CAPACITOR-P291-1503-GEN","price":25.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-P291-1503_60822eb0-d4c4-47db-a236-01776003bf8a.jpg?v=1775038819","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pf1mnb060000aaaa-capacitor-42n4o5","provider":"National HVAC Parts","version":"1.0","type":"link"}
