OEM Carrier Dual Round Run Capacitor 440V for PG8UAA048091ADJA

The dual run capacitor keeps the compressor and condenser fan motor running smoothly in your Carrier PG8UAA048091ADJA package unit. It stores and releases energy to maintain the phase shift these single-phase motors need to run efficiently. When it weakens or fails you'll hear a humming compressor that won't start, see the condenser fan spinning slowly or not at all, feel warm air on a cooling call, or trip the breaker — and a bulged or leaking can top is a dead giveaway. This is a dual round run capacitor, typically rated around 45/5 MFD at 440VAC with HERM (compressor) and FAN terminals, held to OEM ±5% tolerance. The correct microfarad rating is critical — measure with a capacitance meter and replace if the reading drifts more than 5% below the printed value. OEM matters enormously for capacitors. Generic aftermarket caps often ship with ±10–15% tolerance and lower-grade dielectric, so they read out of spec when new and degrade fast in the hot package-unit cabinet. A capacitor feeding the wrong MFD forces the compressor to draw excess amperage, overheating and shortening the life of the windings — a cheap part that can destroy an expensive compressor. Install difficulty: 2 of 5. Tools: 1/4" nut driver, needle-nose pliers, and a multimeter. SAFETY — DISCHARGE THE CAPACITOR before touching the terminals: a charged run capacitor holds a dangerous shock even with power off. Bleed it across the terminals through an insulated-handle screwdriver or resistor, and kill the breaker first. Ships same business day from our stocked warehouse on orders placed before 3 PM CST. Backed by a 1-year OEM warranty and 30-day hassle-free returns on uninstalled parts.

Compatibility

This part is compatible with Carrier model PG8UAA048091ADJA. Always verify the part number against your unit's data plate before ordering.

Why Choose OEM?

OEM parts are manufactured to the exact factory specifications for your unit. Generic aftermarket alternatives may fit physically but often use lower-rated components that reduce equipment life and void manufacturer warranties. When the cost difference between OEM and generic is $10-30, the OEM part is always the smarter investment on a system worth $5,000-$15,000.

Shipping & Returns

Same-day shipping on orders before 3 PM CST. Standard delivery 2-5 business days, express options available at checkout. 30-day hassle-free returns on uninstalled parts — free return shipping included. 1-year OEM factory warranty coverage.

Frequently Asked Questions

Does this Capacitor fit my Carrier PG8UAA048091ADJA?
Yes. This is the factory-specified OEM capacitor for the Carrier PG8UAA048091ADJA. 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 PG8UAA048091ADJA?
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.
