What MFD capacitor do I need for my Goodman AC?

The correct replacement for Goodman model ASZ130181AA — CAP050300440RSS 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 ASZ130181AA — CAP050300440RSS.

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 CAP050300440RSS is a genuine OEM 30/5 MFD, 440-volt dual round run capacitor engineered as a direct-fit replacement for the ASZ130181AA heat pump condensing unit. This capacitor provides the starting torque and continuous run boost for both the compressor and the outdoor condenser fan motor, making it one of the most common failure points in a residential heat pump. A weak or bulging capacitor causes hard starts, humming, tripped breakers, and a unit that fails to cool.

Specifications

Capacitance: 30/5 MFD (µF) dual rating
Voltage: 440 VAC (compatible with 370V applications)
Type: Dual round run capacitor
Terminals: HERM / FAN / C quick-connect
Tolerance: ±6%
Fits: Goodman ASZ130181AA and compatible 1.5-ton heat pumps

OEM vs. Generic

This is the factory-original Goodman part, built to the exact microfarad tolerance and temperature rating specified for your unit. Generic universal capacitors are cheaper but often run wider tolerances and lower cycle-life ratings, which can shorten compressor life. For a critical compressor circuit, we recommend the OEM part.

Installation Difficulty: Easy

A 15-minute repair for a homeowner comfortable with basic tools. Always disconnect power and safely discharge the capacitor before removal. Photograph the wiring first, then transfer leads one terminal at a time (HERM, FAN, C). No refrigerant handling required.

Yes. This is the factory-specified OEM capacitor for the Goodman ASZ130181AA — 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 ASZ130181AA — 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.
