OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1RPA072074ACWA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY1RPA072074ACWA packaged unit. Rated at 4 MFD / 370V in an oval case, it powers the draft inducer motor's permanent split capacitor (PSC) circuit — storing and releasing the precise electrical charge needed to keep the inducer spinning at the correct speed. When this capacitor weakens or fails, the draft inducer motor may hum without turning, run sluggishly, overheat, or trip on thermal overload, resulting in a no-heat lockout condition. Cross-referenced OEM part numbers include HC30GB230 (Draft Inducer Motor w/ Capacitor kit), P291-0403, and P291-1003 (Totaline/Carrier single run capacitors).

  • Specs: 4 MFD (microfarad) | 370V rated | Oval case | ±5% factory tolerance | 50/60 Hz | Rated to 60,000 service hours
  • OEM vs Generic: OEM capacitors are manufactured to exact United Technologies/Carrier specifications with 100% electrical pre-testing and a UL-approved pressure-sensitive interrupter. Generic units often ship with loose tolerances, reducing inducer motor lifespan and risking nuisance lockouts.
  • Install difficulty: 2/5 — Discharge any residual voltage before handling. Disconnect power at the breaker. Tools needed: flathead screwdriver, needle-nose pliers, multimeter (capacitance mode). Always photograph original wiring before disconnecting terminals. Confirm polarity is not required for non-polarized run capacitors.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3 PM local time.

Compatibility: Designed for the Carrier PY1RPA072074ACWA packaged unit draft inducer motor circuit. Verify the 4 MFD and 370V ratings against your unit's data plate before ordering.

Frequently Asked Questions

Does this Capacitor fit my Carrier OEM Carrier Single Run Capacitor 4 MFD 370V — PY1RPA072074ACWA?
Yes. This is the factory-specified OEM capacitor for the Carrier OEM Carrier Single Run Capacitor 4 MFD 370V — PY1RPA072074ACWA. 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 OEM Carrier Single Run Capacitor 4 MFD 370V — PY1RPA072074ACWA?
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?
