OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY1PPA048120AFBA

This is the OEM-specified single run capacitor for the draft inducer motor assembly on the Carrier PY1PPA048120AFBA packaged unit. Cross-referenced under primary assembly part number HC30GB230 and discrete capacitor part number P291-1003, this capacitor provides the continuous run voltage that keeps the inducer blower motor spinning at proper speed throughout every heating cycle. When this capacitor weakens or fails, the draft inducer motor will hum without starting, run erratically, or cause the furnace to lock out on a pressure switch fault — symptoms often misdiagnosed as a failed motor or faulty pressure switch.

  • Specs: 4 MFD (microfarad) | 370VAC rated | Single run capacitor | Factory-matched tolerance for inducer motor HC30GB230 | OEM part numbers: HC30GB230 (assembly), P291-1003 (capacitor)
  • OEM vs Generic: This OEM capacitor is manufactured to exact Carrier factory tolerances (±3% MFD). Generic capacitors often carry a ±10% tolerance, which can cause the inducer motor to run hot, shorten motor life, and void equipment warranties.
  • Install difficulty: 2/5 — Disconnect power and allow capacitor to discharge fully before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (to verify capacitance). Photograph existing wiring before disconnecting terminals. Always confirm MFD and voltage ratings on the original capacitor before installation.
  • Warranty: 1-year OEM factory warranty on parts. Orders ship same business day from our warehouse when placed before cutoff.

Compatibility: Designed for the Carrier PY1PPA048120AFBA packaged unit equipped with the HC30GB230 draft inducer motor assembly. Verify the 4 MFD and 370V ratings against your existing capacitor's data label before ordering. Not sure it fits? Our HVAC parts specialists will verify fitment before you purchase — no guesswork required.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY1PPA048120AFBA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY1PPA048120AFBA. 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 PY1PPA048120AFBA?
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.
