When this part fails, you'll typically see: humming motor that won’t start, hard starting, breaker trips, swollen or leaking capacitor top.

Yes — this part is verified against the manufacturer's parts list for the PH15NA042000BAAA. Have a different model? Search your model number in our store; this part serves other Carrier-family units as well.

Is this an OEM part?

Genuine Carrier Corporation (Payne is a Carrier brand) OEM — the same part your unit was built with, not an aftermarket substitute.

What if it doesn't fit?

We send a prepaid return label and issue a full refund — 30 days, uninstalled parts. Installed or energized parts are non-returnable; manufacturing defects are handled under the manufacturer's warranty.

When will it ship?

Order before 3PM CST and it ships the same business day from Houston, TX.

Can I install it myself?

This part is rated Moderate DIY (15–30 min typical). Comfortable DIYers handle this with basic tools — follow the safety note above.

How do I know the capacitor is the problem and not the motor?

A humming motor that won’t start usually means the capacitor. Test with a multimeter on capacitance mode against the rated µF printed on the label — more than ~6% off means replace it.

Frequently Asked Questions

Does this Capacitor fit my Payne PH15NA042000BAAA — 325437-303?
Yes. This is the factory-specified OEM capacitor for the Payne PH15NA042000BAAA — 325437-303. 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 Payne PH15NA042000BAAA — 325437-303?
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 Payne 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 Payne 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.
