What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model OEM Carrier Single Run Capacitor 10 MFD 370/440V — PH1RPA072000ABWA 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 OEM Carrier Single Run Capacitor 10 MFD 370/440V — PH1RPA072000ABWA.

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 Single Run Capacitor 10 MFD 370/440V for Model PH1RPA072000ABWA

This OEM single run capacitor is the factory-specified replacement for the Carrier PH1RPA072000ABWA packaged heat pump unit. The run capacitor maintains the continuous phase-shifted current that keeps the blower motor or compressor motor spinning at correct speed and torque. When it degrades or fails, you'll notice symptoms including weak or no airflow, a humming blower motor that won't spin up, or the system tripping on high-temperature limit — all classic signs of run capacitor failure.

Specs: 10 MFD (microfarad) | 370/440V dual-rated | Oval case form factor | OEM Part # P291-1003 (superseded by P291-1004) | ±5% factory tolerance
OEM vs Generic: This is a genuine Carrier OEM capacitor matched to factory tolerances. Generic aftermarket capacitors often deviate ±10% MFD, causing increased motor winding heat and accelerated wear — shortening blower motor life significantly.
Install Difficulty: 2/5 — Discharge the capacitor fully before handling any terminals. Tools needed: flathead or Torx screwdriver, needle-nose pliers, multimeter (capacitance mode). Always photograph existing wiring connections before removal.
Warranty: 1-year OEM factory warranty. In stock and ships same business day from our warehouse.

Compatibility: Engineered for the Carrier PH1RPA072000ABWA packaged heat pump. Always verify MFD rating and voltage against your unit's data plate before ordering. Need help confirming fitment? Our HVAC parts specialists are ready to verify compatibility before you buy — no guesswork required.

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).

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.
