OEM Carrier Dual Run Capacitor & Start Capacitor Kit for Model PH4ANG048000BAAA

This factory-matched OEM capacitor kit includes both the dual run capacitor (P291-7073RS / P291-7074R successor, 70+7.5 MFD 370V) and the start capacitor (P281-1766, 175–216 MFD 330V) — the complete capacitor solution for the Carrier PH4ANG048000BAAA 4-ton packaged heat pump. The dual run capacitor maintains continuous electrical energy to both the compressor and condenser fan motor, while the start capacitor delivers the high-torque surge needed to kick the compressor into motion. When either fails, symptoms include a loud hum with no motor start, the system tripping on high-pressure lockout, or the compressor struggling to start before shutting down within seconds.

• Dual Run Capacitor Specs (P291-7073RS): 70+7.5 MFD | 370V rated (440V compatible successor) | Round case | ±6% tolerance | RoHS compliant | Castor oil protected | Tested to 60,000 service hours
• Start Capacitor Specs (P281-1766): 175–216 MFD | 330V | Round case | Provides high-torque compressor start boost — cycles out of circuit once motor reaches operating speed
• OEM vs Generic: OEM Totaline/Carrier capacitors are built to exact factory tolerance and are 100% electrically tested before leaving the factory. Generic capacitors often drift ±10% MFD over time, placing compressor windings under sustained stress and shortening equipment life significantly.
• Install Difficulty: 2/5 — Always discharge capacitors before touching terminals (residual charge can be lethal). Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode), and a camera or phone to photograph wiring before disconnecting. Label all terminals (HERM, FAN, COM, and start cap leads) prior to removal.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse when ordered by 3 PM local time.

Compatibility: Engineered specifically for the Carrier PH4ANG048000BAAA 4-ton packaged heat pump unit. Always verify MFD ratings and voltage against your unit's data plate before ordering — running mismatched capacitors will void compressor warranties. Our team is available to verify fitment before you buy. Order now — in stock and ships today.
