What MFD capacitor do I need for my Goodman AC?

The correct replacement for Goodman model WGHP4660AAE — 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 WGHP4660AAE — 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.

Restore reliable starting and running performance with the genuine Goodman CAP050800440RTS 80/5 MFD 440V Dual Run Capacitor, built specifically for the Goodman WGHP4660AAE air conditioner. This dual-rated capacitor supplies the phase-shifted current that both the compressor (80 MFD) and the condenser fan motor (5 MFD) need to start and run efficiently. A failing capacitor is the single most common cause of a humming-but-not-starting compressor, a fan that won't spin, or a unit that trips on overload during hot weather.

Specifications

Capacitance: 80/5 MFD (microfarad), dual-rated
Voltage: 440 VAC (also serves 370V applications)
Terminals: HERM (compressor), FAN, and C (common)
Tolerance: ±6%
Shape: Round, oil-filled
OEM part number: CAP050800440RTS
Compatible model: Goodman WGHP4660AAE

OEM vs. Generic

The OEM Goodman CAP050800440RTS is matched to the unit's compressor and fan-motor electrical load, with terminal layout and microfarad ratings the control board expects. Generic capacitors of nominally the same rating can drift out of tolerance faster under high ambient heat, shortening compressor life. The factory part protects your most expensive component.

Install Difficulty

Moderate (2 of 5) — Requires shutting off power at the disconnect and safely discharging the old capacitor before swapping the HERM, FAN, and C leads. A 15-minute job for a tech; DIYers must observe capacitor-discharge safety.

OEM fit guaranteed with fast shipping on in-stock orders.

Frequently Asked Questions

Does this Capacitor fit my Goodman WGHP4660AAE — CAP050800440RTS?

Yes. This is the factory-specified OEM capacitor for the Goodman WGHP4660AAE — 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 WGHP4660AAE — 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.

How fast does National HVAC Parts ship?
