What MFD capacitor do I need for my Goodman AC?

The correct replacement for Goodman model DSX160601AA — 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 DSX160601AA — 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 Dual Run Capacitor is a genuine OEM component rated 80/5 MFD at 440V for the Goodman DSX160601AA 16 SEER air conditioner. This dual-section capacitor provides the starting and running torque for both the compressor (80 MFD) and the condenser fan motor (5 MFD). A weak or bulging capacitor is the single most common cause of an AC that hums but won't start, trips the breaker, or fails to cool — replacing it with the correct OEM rating restores reliable startup.

OEM vs. Generic

This genuine Goodman capacitor delivers the exact 80/5 MFD rating and 440V tolerance your unit was designed around. While generic dual-run capacitors of matching microfarad values exist, OEM units offer verified ratings, terminal layout, and the higher 440V endurance that extends service life in hot outdoor conditions.

Install Difficulty

Moderate — Capacitors store a dangerous electrical charge even with power off and must be safely discharged before handling. Photograph the HERM / FAN / C terminal wiring before disconnecting. Disconnect power at the breaker first. If you are not experienced with discharging capacitors, hire a licensed HVAC technician.

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.
