This OEM capacitor kit includes both the P291-8073RS dual run capacitor (80+7.5 MFD / 370V) and the P281-1766 start capacitor (175–216 MFD / 330V) — the exact factory-specified pair for the Carrier PH3ANA060000BBAA packaged heat pump unit. The dual run capacitor continuously energizes both the compressor and the condenser fan motor during operation, while the start capacitor delivers the high-torque burst needed to get the compressor off the ground on each cycle. When either fails, symptoms range from a low humming noise and no cooling output, to hard-start lockouts or a compressor that starts briefly then drops offline.
Compatibility: Engineered for the Carrier PH3ANA060000BBAA 5-ton packaged heat pump. Verify MFD ratings and voltage against your unit's data plate before ordering — mismatched capacitors can cause compressor damage. Not sure? Our HVAC parts specialists verify fitment before you order. In stock — order by 3 PM for same-day shipping.
