What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PH13NR042000AEAA is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Carrier equipment which lists the model number PH13NR042000AEAA.

My AC hums but will not start. What part do I need?

An AC that hums but will not start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost needed to start the compressor and fan motors. When it fails, you hear the hum of the motor trying to start but it cannot overcome inertia. Other symptoms include the fan spinning slowly, the AC cycling on and off rapidly, or a visibly swollen or leaking capacitor. Replacement cost: $15 to $80 for the part, DIY in 30 minutes.

Is this capacitor compatible with Bryant or Payne systems too?

Many Carrier parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

OEM Carrier Dual Run Capacitor & Start Capacitor Kit for Model PH13NR042000AEAA

This OEM-matched capacitor kit includes both the P291-5573RS Dual Run Capacitor and the P281-8806 Start Capacitor — the factory-specified replacements for the Carrier PH13NR042000AEAA heat pump condenser. The dual run capacitor provides continuous run support to both the compressor and condenser fan motor, while the start capacitor delivers the high-torque electrical boost needed to get the compressor spinning under load. When either fails, symptoms range from a loud hum with no motor movement, to the unit short-cycling, tripping the breaker, or failing to cool or heat entirely.

Included Parts: P291-5573RS Dual Run Capacitor (compressor + fan) | P281-8806 Start Capacitor (compressor hard-start assist) | Factory-matched MFD and voltage ratings | Verify exact specs on your unit data plate before installing
OEM vs Generic: These OEM capacitors meet Carrier's precise factory tolerance (±3% MFD). Generic alternatives commonly run ±10% tolerance, which accelerates compressor wear, shortens motor life, and can void equipment warranties.
Install Difficulty: 3/5 — Always disconnect power at the breaker and discharge the capacitor before handling. Tools needed: 1/4" and 5/16" nut drivers, insulated needle-nose pliers, and a multimeter capable of MFD testing. Photograph all wiring connections before disconnecting. Start capacitor wiring must be routed through the PTCR or hard-start relay if present.
Warranty & Shipping: 1-year OEM factory warranty on both capacitors. Orders placed before 3 PM ship the same business day from our stocked warehouse.

Compatibility: Engineered as direct OEM replacements for the Carrier PH13NR042000AEAA R-410A heat pump condenser. Always cross-reference the MFD rating, voltage rating (370V or 440V), and terminal configuration printed on your existing capacitor's label before finalizing your order. Our HVAC parts specialists are available to verify fitment — contact us before you buy if you have any questions.

Frequently Asked Questions

Does this Capacitor fit my Carrier PH13NR042000AEAA?

Yes. This is the factory-specified OEM capacitor for the Carrier PH13NR042000AEAA. 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 PH13NR042000AEAA?

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.
