OEM Carrier Dual Run Capacitor 70+7.5 MFD 370V & Start Capacitor Kit for Model PH15NA04800GBAAA

This OEM-specification capacitor kit includes both the dual run capacitor (P291-7073RS / superseded by P291-7074R) and the start capacitor (P281-1766) — the factory-matched pair for the Carrier PH15NA04800GBAAA Comfort 15 heat pump condenser. The dual run capacitor continuously energizes the compressor and condenser fan motor during operation, while the start capacitor delivers the extra voltage surge needed to spin the compressor up from a standstill. When either fails, you'll experience a humming unit that won't start, a compressor that trips on thermal overload, or a system that short-cycles within the first few minutes of operation.

  • Dual Run Capacitor Specs (P291-7073RS → P291-7074R): 70+7.5 MFD | 370V/440V rated | Round case, 2.5" diameter | ±6% tolerance | 50/60 Hz | 10,000 AFC | RoHS compliant | UL approved | Castor oil-filled, no PCB
  • Start Capacitor Specs (P281-1766): 175–216 MFD | 330V | Round case | Factory-specified boost capacitor for compressor hard-start assist
  • OEM vs Generic: OEM Totaline/Carrier capacitors are reliability-tested to 60,000 service hours per United Technologies application parameters with 100% electrical testing at the factory. Generic capacitors frequently run outside ±6% MFD tolerance, accelerating compressor wear and increasing hard-start failures — especially critical on a 4-ton R-410A heat pump compressor.
  • Install Difficulty: 2/5 — Always discharge the run capacitor before touching terminals (use an insulated resistor or discharge tool). Tools needed: 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wiring before disconnecting. Note: P291-7073RS is superseded by P291-7074R — the updated 370/440V dual-rated version is a direct drop-in replacement.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

Compatibility: Factory-matched OEM capacitor kit for the Carrier PH15NA04800GBAAA Comfort 15 4-ton heat pump condenser. Always verify MFD ratings and voltage on your unit's data plate before installing. Not sure if this fits? Our HVAC parts specialists verify fitment before you order — order with confidence and get back to cool faster.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Dual Run & Start Capacitor Kit 70+7.5 MFD 370V — PH15NA048?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Dual Run & Start Capacitor Kit 70+7.5 MFD 370V — PH15NA048. 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 & Start Capacitor Kit 70+7.5 MFD 370V — PH15NA048?
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.
