OEM Carrier Dual Run & Start Capacitor Kit for Model CA16NA04800GBAAA

This OEM capacitor kit includes both the dual run capacitor (P291-4573RS) and the start capacitor (P281-1766) factory-specified for the Carrier CA16NA04800GBAAA 4-ton split-system air conditioner. Together, these capacitors provide the electrical charge required to start and sustain the compressor and condenser fan motor during every cooling cycle. A failing dual run capacitor typically presents as a humming condenser with no motor movement, short-cycling, or a system that trips the breaker repeatedly. A failed start capacitor prevents the compressor from starting under load, often resulting in a hard-start condition or complete lockout.

  • Specs: P291-4573RS — Dual Run Capacitor, 440V rated, round case, factory-matched ±3% MFD tolerance | P281-1766 — Start Capacitor, high-boost design for compressor hard-start assist | Both units meet original Carrier factory specifications for the CA16NA04800GBAAA platform.
  • OEM vs Generic: OEM capacitors are manufactured to exact factory tolerances. Aftermarket/generic units frequently deviate ±10% MFD or more, which accelerates wear on the compressor windings and condenser fan motor bearings — shortening system lifespan significantly.
  • Install Difficulty: 2/5 — Always discharge capacitors fully before handling — stored voltage can exceed 370V and is dangerous. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter with capacitance mode. Photograph all wiring connections before disconnecting terminals.
  • Warranty: 1-year OEM factory warranty on both components. Orders ship same business day from our climate-controlled warehouse.

Compatibility: This kit is engineered specifically for the Carrier CA16NA04800GBAAA 4-ton (48,000 BTU) single-stage R-410A split-system condenser. Always verify capacitor MFD and voltage ratings against your unit's data plate before installation. If you're unsure of fitment, our HVAC parts specialists are available to confirm compatibility before you order — same-day shipping on all in-stock OEM parts.

Frequently Asked Questions

Does this Capacitor fit my Carrier CA16NA04800GBAAA?
Yes. This is the factory-specified OEM capacitor for the Carrier CA16NA04800GBAAA. 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 CA16NA04800GBAAA?
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.
