OEM Carrier Run Capacitor P291-0500R45 for Model CGH12520D

This OEM Carrier P291-0500R45 run capacitor delivers the steady startup torque and continuous voltage your CGH12520D gas package unit needs to keep its condenser fan motor and compressor running efficiently. A weak or bulged capacitor causes hard starts, humming, tripped breakers, and a system that won't cool. This factory-spec dual round capacitor is engineered to the exact microfarad and voltage rating Carrier built into the CGH12520D, so you get reliable operation and full equipment lifespan without guesswork. Installation is straightforward for an experienced DIYer or HVAC tech—discharge the old capacitor, photograph the wiring, swap terminals, and restore power in under 20 minutes. Always shut off power at the disconnect first. Because it's a genuine OEM component, it carries the correct tolerance Carrier requires to protect your motor windings. In stock and ships same-day when you order before 3PM CST. Restore quiet, dependable cooling to your CGH12520D with the part Carrier engineered for it.

Frequently Asked Questions

Does this Run Capacitor fit my Carrier Model CGH12520D?
Yes. This is the factory-specified OEM run capacitor for the Carrier Model CGH12520D. 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 run capacitor on my Carrier Model CGH12520D?
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 run 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 run 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?
