OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V for Model PH14NA04800GBAAA

This OEM dual run capacitor is the factory-specified replacement for the Carrier PH14NA04800GBAAA heat pump condenser. The dual run capacitor stores and delivers the electrical charge required to start and sustain both the compressor and condenser fan motor simultaneously. When this component weakens or fails, you'll notice symptoms such as the compressor humming without starting, the condenser fan failing to spin, the system short-cycling, or a complete no-cooling condition. This unit ships under OEM part number P291-7073RS (superseded by P291-7074R), both of which are fully interchangeable on your PH14NA04800GBAAA. The system also uses a companion start capacitor P281-1766 (175–216 MFD, 330V) — if your compressor is struggling to start, replacing both together is best practice and eliminates a second service call.

  • Specs — Dual Run Capacitor (P291-7073RS / P291-7074R): 70+7.5 MFD (microfarad) | 370V rated (440V compatible) | Round case, 2.5" diameter | ±6% tolerance | RoHS Compliant | UL Approved | Castor oil protected, no PCB | Tested to 60,000 service hours
  • OEM vs Generic: OEM Totaline/Carrier capacitors are manufactured to exact factory tolerance (±6%), ensuring proper compressor and fan motor operation. Generic aftermarket capacitors often carry ±10% MFD variance, which accelerates motor winding stress and shortens compressor life — especially critical on a 4-ton heat pump running long cycles.
  • Install difficulty: 2/5 — Always discharge the capacitor before touching any terminals (use an insulated resistor or screwdriver across terminals). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance function). Photograph all wire connections before removal. Takes approximately 20–30 minutes.
  • Warranty & Shipping: 1-year OEM manufacturer warranty against defects. In stock and ships same business day from our warehouse when ordered before 3PM local time.

Compatibility: Fits Carrier model PH14NA04800GBAAA heat pump condensers. OEM part numbers P291-7073RS and its direct successor P291-7074R are fully interchangeable. Also cross-references GE/Genteq C37075R and 27L556. Always verify the MFD and voltage rating on your unit's data plate before ordering — our team is available to confirm fitment. Order today and get your system cooling again by tomorrow.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V — PH14NA04800GBAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V — PH14NA04800GBAAA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the capacitor on my Carrier OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V — PH14NA04800GBAAA?
Difficulty: Easy (20–30 min)
Step 1: Turn off power at breaker. Step 2: Open condensing unit panel. Step 3: Photograph the old capacitor wiring (Common/Herm/Fan). Step 4: Discharge old capacitor with insulated screwdriver. Step 5: Disconnect and remove old capacitor. Step 6: Mount new capacitor, reconnect wires to matching terminals. Step 7: Close panel, restore power, test. Tools: screwdriver, needle-nose pliers.
My AC hums but won’t start. What part do I need?
An AC that hums but won’t start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost to start the compressor. When it fails, you hear humming but the motor can’t overcome inertia. Other symptoms: fan spinning slowly, AC cycling on/off rapidly, or a visibly swollen capacitor. Fix: replace capacitor ($15–$80 DIY, 30 min).
Is this capacitor compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier capacitor?
OEM strongly recommended. OEM capacitors have ±6% MFD tolerance vs aftermarket ±10%. The looser tolerance causes motor winding stress, higher temps, and shorter compressor life. Price difference is only $10–$20 — OEM is the clear value choice.
How fast does National HVAC Parts ship?
Orders placed before 3:00 PM CST ship the same business day. Standard delivery is 2–5 business days anywhere in the continental United States. Express shipping available at checkout. We ship from Houston, TX to all 50 states. 30-day return policy on all parts.
