OEM Carrier Single Run Capacitor 4 MFD 370V for Model PY2PEB042060AA

This OEM single run capacitor is the factory-specified replacement for the Carrier PY2PEB042060AA packaged unit. The run capacitor stays in the circuit continuously while the motor operates, providing the phase-shifted electrical charge needed to keep the fan motor running efficiently and smoothly. When it degrades or fails, symptoms typically include a humming condenser or blower motor that won't spin, the system short-cycling within seconds of startup, or the unit running warm due to a struggling motor drawing excess amperage.

  • Specs: 4 MFD (microfarad) | 370 VAC rated | Oval case | OEM part numbers: P291-0403 (primary), P291-1503 (secondary) | Replaces legacy P/N 97F5704 | Factory-matched tolerance
  • OEM vs Generic: This OEM capacitor is built to Carrier's exact factory specification, including high-grade metallized polypropylene film dielectric and a UL-approved pressure-sensitive interrupter for safe fail-open protection. Generic capacitors often run at wider MFD tolerances, accelerating motor wear and risking premature compressor failure.
  • Install difficulty: 2/5 — Always shut off power at the disconnect and wait 5 minutes for the capacitor to fully discharge before touching any terminals. Tools needed: 1/4" nut driver, insulated needle-nose pliers, multimeter (capacitance mode). Photograph all wiring connections before disconnecting.
  • Warranty: 1-year OEM factory warranty. In-stock and ships same business day from our warehouse.

Compatibility: Engineered as a direct OEM replacement for the Carrier PY2PEB042060AA packaged unit. Always verify the MFD rating and voltage printed on your existing capacitor's label before ordering — substituting a higher voltage (440V) unit of the same MFD is acceptable, but MFD must match exactly.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY2PEB042060AA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY2PEB042060AA. 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 PY2PEB042060AA?
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.
