What MFD capacitor do I need for my Goodman AC?

The correct replacement for Goodman model WGHP4660ABA — CAP050800440RTS is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Goodman equipment which lists the model number WGHP4660ABA — CAP050800440RTS.

My AC hums but will not start. What part do I need?

An AC that hums but will not start is the classic symptom of a failed capacitor. The capacitor provides the electrical boost needed to start the compressor and fan motors. When it fails, you hear the hum of the motor trying to start but it cannot overcome inertia. Other symptoms include the fan spinning slowly, the AC cycling on and off rapidly, or a visibly swollen or leaking capacitor. Replacement cost: $15 to $80 for the part, DIY in 30 minutes.

Is this capacitor compatible with Bryant or Payne systems too?

Many Goodman parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

The Goodman CAP050800440RTS is a genuine OEM dual run capacitor engineered for the WGHP4660ABA air conditioner / heat pump and compatible Goodman, Amana, and Janitrol units. It supplies the phase-shifted starting and running torque for both the compressor and the condenser fan motor from a single round can, keeping your system running efficiently and quietly.

A weak or bulging capacitor is one of the most common causes of a unit that hums but won't start, trips the breaker, or short-cycles in hot weather. Installing the correct rated part restores full performance and protects the compressor from overheating.

Specifications

Capacitance: 80/5 MFD (dual run)
Voltage: 440V (compatible with 370V applications)
Tolerance: ±6%
Shape: Round can
Terminals: Quick-connect spade
Fits: Goodman WGHP4660ABA and compatible models

OEM vs. Generic

Our OEM Goodman capacitor is built to factory voltage tolerance and lifecycle ratings for an exact electrical match and long service life. Quality generic equivalents offer the same 80/5 MFD / 440V ratings at lower cost and are a sound choice for budget repairs, though OEM is recommended where warranty or maximum longevity matters.

Installation Difficulty

Easy (DIY-friendly, ~15 minutes). Requires basic hand tools. Warning: capacitors store a lethal charge — always disconnect power and discharge the capacitor with an insulated resistor before handling. If you are not comfortable working around live electrical components, hire a licensed HVAC technician.

Yes. This is the factory-specified OEM capacitor for the Goodman WGHP4660ABA — CAP050800440RTS. 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 Goodman WGHP4660ABA — CAP050800440RTS?

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 Goodman 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 Goodman 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.
