OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY3PPA060090AA

This is the factory-specified OEM single run capacitor for the Carrier PY3PPA060090AA packaged rooftop unit. The run capacitor stores and releases electrical energy to keep the fan motor running smoothly and efficiently throughout each cooling or heating cycle. When this capacitor weakens or fails, you'll notice symptoms such as a fan motor that hums but won't spin, a motor that overheats and trips on thermal overload, or a unit that short-cycles and fails to maintain setpoint — all signs it's time for an immediate replacement.

  • Specs: 4 MFD (microfarad) | 370 VAC | Oval case | OEM part numbers: P291-0403 / P291-2503 | Also replaces: HC90AA004, HC91CA004, 97F5704
  • OEM Quality Advantage: Built to Carrier factory tolerances with high-grade metallized polypropylene film, UL-approved pressure-sensitive interrupter, and 100% electrical testing. Generic capacitors often run out of spec, accelerating motor wear and voiding equipment warranties.
  • Install Difficulty: 1/5 — One of the easiest HVAC repairs. Shut off power at the disconnect, wait 5 minutes for the capacitor to fully discharge, photograph existing wiring, swap terminals one at a time, and restore power. Tools needed: flathead or 1/4" nut driver, needle-nose pliers, and a multimeter to verify capacitance before and after.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. In stock and ships same business day from our warehouse — order by 3 PM local time to go out today.

Compatibility: Direct OEM replacement for Carrier model PY3PPA060090AA packaged rooftop units. Always verify the MFD rating and voltage on your unit's data plate before ordering — the voltage rating must match or exceed the original specification. Our parts specialists are available to confirm fitment before you purchase.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3PPA060090AA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY3PPA060090AA. 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 PY3PPA060090AA?
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.
