What MFD capacitor do I need for my Carrier AC?

The correct replacement for Carrier model PY1RPA036074ABWA 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 PY1RPA036074ABWA.

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 4 MFD 370V for Model PY1RPA036074ABWA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1RPA036074ABWA furnace. Sourced directly from the draft inducer motor assembly (OEM part HC30GB230), this 4 MFD 370V oval capacitor supplies the phase-shift current that starts and sustains the inducer motor on every heating cycle. When this capacitor fails, the draft inducer motor will hum without spinning, fail to prove combustion airflow, and trigger a pressure switch lockout — leaving you with no heat. Replacing it early prevents costly motor burnout.

Specs: 4 MFD (microfarad) | 370V rated | Oval case | Factory-matched ±5% tolerance | 50/60Hz | Cross-references: HC30GB230, P291-0403, P291-1003, HC90AA004, HC91CA004, HC90AB004
OEM vs Generic: This is the genuine Carrier/Totaline OEM capacitor — reliability tested to 60,000 service hours with UL-approved pressure-sensitive interrupter. Generic alternatives often carry ±10% MFD tolerance, which accelerates inducer motor winding wear and shortens motor life.
Install difficulty: 2/5 — Disconnect power and verify zero voltage before touching any terminals. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (capacitance mode). Always photograph wiring orientation before disconnecting the old capacitor. Discharge the old capacitor safely through a resistor before handling.
Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for Carrier model PY1RPA036074ABWA furnace units using the HC30GB230 draft inducer motor assembly. Verify the 4 MFD and 370V ratings on your unit's data plate or existing capacitor before ordering. Not sure it's the right fit? Our HVAC parts specialists verify fitment before you buy — just reach out.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1RPA036074ABWA?

Yes. This is the factory-specified OEM capacitor for the Carrier PY1RPA036074ABWA. 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 PY1RPA036074ABWA?

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?
