OEM Carrier Dual Run Capacitor 70+5 MFD 370V for Model PY3GNA048090NA

This OEM-spec dual run capacitor (part number P291-7053RS) is the factory-matched replacement for Carrier model PY3GNA048090NA packaged HVAC systems. The dual run capacitor stores and delivers the electrical charge required to start and sustain both the compressor motor and the condenser fan motor simultaneously from a single round canister. When this capacitor weakens or fails, common symptoms include a loud humming sound with no motor startup, a system that trips on high-pressure lockout within minutes of starting, a condenser fan that spins slowly or not at all, or a compressor that draws high amperage and overheats. Replacing this capacitor promptly protects your compressor — the most expensive component in the system — from premature failure.

  • Specs: 70+5 MFD (microfarad) | 370/440V dual-rated | Round case | ±5% factory tolerance | 50/60 Hz | Replaces P291-7053RS, P291-7054R, C3705R, 27L633, HC98JA071
  • OEM vs Generic: OEM-spec capacitors are wound and sealed to exact factory tolerance. Off-brand capacitors frequently drift beyond ±10% MFD under heat load, accelerating compressor wear and shortening service life — particularly critical on high-demand 4-ton packaged units like the PY3GNA048090NA.
  • Install difficulty: 2/5 — Always discharge the capacitor terminals with an insulated resistor tool before handling. Tools needed: 1/4" nut driver, needle-nose pliers, multimeter (capacitance mode to verify before install). Photograph all wiring connections before disconnecting the old capacitor. Swap terminals one at a time to avoid miswiring HERM, FAN, and COMMON posts.
  • Warranty: 1-year replacement warranty. In-stock and ships same business day from our warehouse.

Compatibility: Verified fit for Carrier model PY3GNA048090NA packaged gas/electric units. Also cross-references Bryant and Payne models sharing the 70+5 MFD 370V specification. Always confirm MFD rating and voltage on your unit's data plate or wiring diagram before ordering. Our parts specialists are available to verify fitment — contact us before you order if you have any questions.

Frequently Asked Questions

Does this Capacitor fit my Carrier PY3GNA048090NA?
Yes. This is the factory-specified OEM capacitor for the Carrier PY3GNA048090NA. 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 PY3GNA048090NA?
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.
