The run capacitor maintains a continuous phase-shifted current to keep the blower motor spinning at rated speed throughout every heating cycle. When it degrades or fails, the blower motor may hum without starting, run sluggishly, overheat, or stall entirely — reducing airflow, triggering limit switches, and ultimately causing furnace lockout. Replacing this low-cost component proactively is one of the most effective preventive maintenance steps you can take on any Carrier furnace.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 10 MFD (microfarad) ±6% | 370V rated | Oval case | 50\/60 Hz | Non-PCB castor oil dielectric | UL-approved current interrupter | Multiple electrical terminals | –40°C to +70°C operating range\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is the genuine Carrier-branded (Totaline) capacitor built to factory ±6% MFD tolerance. Off-brand generic capacitors often ship at ±10% or worse, causing the blower motor to run hotter and shortening its service life. OEM match means zero guesswork on fitment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstall difficulty: 1\/5\u003c\/strong\u003e — One of the easiest furnace repairs available. Tools needed: flathead or Torx screwdriver (access panel), needle-nose pliers, multimeter (recommended to confirm capacitor failure before ordering).

Note: Carrier sources capacitors from third-party manufacturers — the label on the capacitor will reflect the component manufacturer's name (e.g., Totaline\/Hartland Controls), not Carrier. This is normal and does not affect fitment or warranty. Verify the 10 MFD and 370V ratings on your unit's data plate before ordering. Have a fitment question? Our HVAC parts specialists verify compatibility before you buy — order with confidence.\u003c\/p\u003e","brand":"Carrier","offers":[{"title":"OEM","offer_id":62642756551027,"sku":"CARRIE-PG8UAA048091ACJA-CAPACITOR-P291-1003","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Generic","offer_id":62642756583795,"sku":"CARRIE-PG8UAA048091ACJA-CAPACITOR-P291-1003-GEN","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-capacitor-P291-1003_3bd38f41-1280-4729-af22-7a15e255c73f.jpg?v=1775038744","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pg8uaa048091acja-capacitor-42n3s0","provider":"National HVAC Parts","version":"1.0","type":"link"}
