The Goodman CAP050300440RSS is a genuine OEM 30/5 MFD, 440-volt dual run capacitor for the WGHP4318AAA packaged air conditioner. This round-can capacitor provides the starting and running torque for both the compressor (30 MFD HERM terminal) and the condenser fan motor (5 MFD FAN terminal) from a single component. A bulging top, weak cooling, or a hard-starting/humming compressor are classic symptoms of a failing capacitor.

  • OEM Part Number: CAP050300440RSS
  • Capacitance: 30/5 MFD (µF) dual rated
  • Voltage: 440 VAC (also compatible in 370V applications)
  • Type: Round can dual run capacitor
  • Terminals: HERM (compressor) + FAN (motor) + C (common)
  • Fits: Goodman WGHP4318AAA package unit

OEM vs. Generic: Generic capacitors are widely available, but tolerance drift and lower-grade dielectric film shorten service life. The 440V rating on this OEM unit gives more thermal headroom than a 370V generic, and the genuine part guarantees the exact MFD split your motors are tuned for.

Install Difficulty: Easy (2/5). A capable tech replaces this in about 10–15 minutes. Disconnect power, discharge the capacitor across its terminals with an insulated resistor before touching it, photograph the HERM/FAN/C wiring, then transfer leads to the matching terminals on the new capacitor.

Frequently Asked Questions

Does this Capacitor fit my Goodman OEM Goodman 30/5 MFD 440V Dual Run Capacitor — CAP050300440RSS?
Yes. This is the factory-specified OEM capacitor for the Goodman OEM Goodman 30/5 MFD 440V Dual Run Capacitor — CAP050300440RSS. 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 OEM Goodman 30/5 MFD 440V Dual Run Capacitor — CAP050300440RSS?
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?
