What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PY1RPA120180ABWB 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 PY1RPA120180ABWB.

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 Capacitor Kit — Dual Run 10/10 MFD & Single Run 4 MFD 370V for Model PY1RPA120180ABWB

This factory-authorized OEM capacitor kit is the correct replacement for the Carrier PY1RPA120180ABWB packaged unit. The kit covers three associated OEM part numbers: HC30GB230 (Draft Inducer Motor w/ Capacitor), P291-1013 (Dual Run Capacitor, 10/10 MFD 370V Oval), and P291-0403 (Single Run Capacitor, 4 MFD 370V Oval). Capacitors store and release the electrical charge needed to start and sustain motor operation — including the compressor, condenser fan, and draft inducer. When a capacitor fails, symptoms typically include a persistent hum with no motor start, the unit short-cycling, or a draft inducer lockout fault code triggered during the ignition sequence.

Specs: P291-1013 — Dual Run, Oval, 10/10 MFD, 370 VAC, 50/60 Hz | P291-0403 — Single Run, Oval, 4 MFD, 370 VAC | HC30GB230 — Draft Inducer Motor Capacitor, 4 MFD 370 VAC | All rated for permanent split-capacitor (PSC) motor applications
OEM vs Generic: Genuine Carrier/Totaline capacitors are reliability-tested to 60,000 service hours with high-grade metallized polypropylene film and a UL-approved pressure-sensitive interrupter. Generic capacitors typically run ±10% MFD tolerance, accelerating motor wear and increasing the risk of premature compressor failure.
Install difficulty: 2/5 — Shut off power and allow 5+ minutes for capacitor discharge before touching terminals. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance setting). Always photograph wiring before disconnecting. Dual run cap terminals are labeled C (common), HERM (compressor), and FAN — ensure each wire returns to its correct terminal.
Warranty: 1-year OEM factory warranty. In-stock units ship same business day from our warehouse.

Compatibility: Engineered for Carrier model PY1RPA120180ABWB. Verify MFD rating, voltage, and capacitor style against your unit's data plate and wiring diagram before ordering. Cross-references include Totaline P291-1013 (superseded by P291-1014), P291-0403 (superseded by P291-0404), and HC30GB230 (superseded by HC30GR231). Not sure which cap you need?

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1RPA120180ABWB?

Yes. This is the factory-specified OEM capacitor for the Carrier PY1RPA120180ABWB. 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 PY1RPA120180ABWB?

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.
