OEM Carrier Single Run Capacitor P291-3504 for Model YAC3680YAC106

This OEM single run capacitor (part number P291-3504) is the factory-specified replacement for the Carrier YAC3680YAC106 split-system air conditioner. A single run capacitor provides the continuous electrical charge needed to keep either the compressor or the condenser fan motor running at peak efficiency throughout each cooling cycle. When this capacitor begins to fail, you'll commonly experience symptoms such as a loud humming with no motor movement, intermittent hard starting, a tripped breaker, or a system that short-cycles and shuts down within minutes of startup.

  • Specs: Single run capacitor | Factory-matched MFD and voltage rating | Round or oval case (factory original) | Meets OEM ±3% microfarad tolerance for precise motor protection
  • OEM vs Generic: This is a genuine OEM Carrier part, manufactured to exact factory specifications. Generic alternatives commonly carry a ±10% MFD tolerance, which places added thermal stress on the motor windings and can significantly shorten compressor or fan motor service life.
  • Install Difficulty: 2/5 — Always discharge the capacitor fully before handling any terminals. Recommended tools: 1/4" and 5/16" nut drivers, needle-nose pliers, and a multimeter capable of MFD measurement. Photograph all wiring connections before disconnecting the old capacitor.
  • Warranty: Backed by a 1-year OEM factory warranty. In-stock units ship same business day from our warehouse when ordered before cutoff.

Compatibility: Designed specifically for the Carrier YAC3680YAC106 condenser unit. Always verify the MFD and voltage ratings on your unit's data plate before ordering to confirm fitment. Not sure? Our HVAC parts specialists are available to verify compatibility before you complete your purchase — get it right the first time and avoid costly return shipping.

Frequently Asked Questions

Does this Capacitor fit my Carrier YAC3680YAC106?
Yes. This is the factory-specified OEM capacitor for the Carrier YAC3680YAC106. 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 YAC3680YAC106?
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.
